Revert "lib/streamaggr: do not flush dedup shards in parallel"
This reverts commit eb40395a1c.

Reason for revert: it has been appeared that the performance gain on multiple CPU cores
wasn't visible because the benchmark was generating incorrect pushSample.key.

lib/streamaggr: properly drop samples on the first incomplete interval
Previously samples were dropped on the first incomplete interval and the next complete interval.
Also make sure that the de-duplication is performed just before flushing the aggregate state.

lib/streamaggr: enable time alignment for aggregate flushed to multiples of interval
For example, if `interval: 1m`, then data flush occurs at the end of every minute,
while `interval: 1h` leads to data flush at the end of every hour.

Add `no_align_flush_to_interval` option, which can be used for disabling the alignment.

lib/promutils: optimize LabelsCompressor.Decompress by using a specialized labelsMap struct instead of sync.Map
The labelsMap struct employs the fact that label indexes are condensed around 0,
so it stores the referred labels in a slice instead of map and uses slice index as label key.
This allows increasing the LabelsCompressor.Decompress performance by up to 3x.
This also reduces the latency of data flush in stream aggregation.

lib/streamaggr: huge pile of changes
- Reduce memory usage by up to 5x when de-duplicating samples across big number of time series.
- Reduce memory usage by up to 5x when aggregating across big number of output time series.
- Add lib/promutils.LabelsCompressor, which is going to be used by other VictoriaMetrics components
  for reducing memory usage for marshaled []prompbmarshal.Label.
- Add `dedup_interval` option at aggregation config, which allows setting individual
  deduplication intervals per each aggregation.
- Add `keep_metric_names` option at aggregation config, which allows keeping the original
  metric names in the output samples.
- Add `unique_samples` output, which counts the number of unique sample values.
- Add `increase_prometheus` and `total_prometheus` outputs, which ignore the first sample
  per each newly encountered time series.
- Use 64-bit hashes instead of marshaled labels as map keys when calculating `count_series` output.
  This makes obsolete https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5579
- Expose various metrics, which may help debugging stream aggregation:
  - vm_streamaggr_dedup_state_size_bytes - the size of data structures responsible for deduplication
  - vm_streamaggr_dedup_state_items_count - the number of items in the deduplication data structures
  - vm_streamaggr_labels_compressor_size_bytes - the size of labels compressor data structures
  - vm_streamaggr_labels_compressor_items_count - the number of entries in the labels compressor
  - vm_streamaggr_flush_duration_seconds - a histogram, which shows the duration of stream aggregation flushes
  - vm_streamaggr_dedup_flush_duration_seconds - a histogram, which shows the duration of deduplication flushes
  - vm_streamaggr_flush_timeouts_total - counter for timed out stream aggregation flushes,
    which took longer than the configured interval
  - vm_streamaggr_dedup_flush_timeouts_total - counter for timed out deduplication flushes,
    which took longer than the configured dedup_interval
- Actualize docs/stream-aggregation.md

The memory usage reduction increases CPU usage during stream aggregation by up to 30%.

app/{vminsert,vmagent}: follow-up after 67a55b89a4
- Document the ability to read OpenTelemetry data from Amazon Firehose at docs/CHANGELOG.md

- Simplify parsing Firehose data. There is no need in trying to optimize the parsing with fastjson
  and byte slice tricks, since OpenTelemetry protocol is really slooow because of over-engineering.
  It is better to write clear code for better maintanability in the future.

- Move Firehose parser from /lib/protoparser/firehose to lib/protoparser/opentelemetry/firehose,
  since it is used only by opentelemetry parser.

lib/{storage,mergeset}: properly fix 'unaligned 64-bit atomic operation' panic on 32-bit architectures
The issue has been introduced in bace9a2501
The improper fix was in the d4c0615dcd ,
since it fixed the issue just by an accident, because Go comiler aligned the rawRowsShards field
by 4-byte boundary inside partition struct.

The proper fix is to use atomic.Int64 field - this guarantees that the access to this field
won't result in unaligned 64-bit atomic operation. See https://github.com/golang/go/issues/50860
and https://github.com/golang/go/issues/19057

lib/{mergeset,storage}: convert bufferred items to searchable parts more optimally
Do not convert shard items to part when a shard becomes full. Instead, collect multiple
full shards and then convert them to a searchable part at once. This reduces
the number of searchable parts, which, in turn, should increase query performance,
since queries need to scan smaller number of parts.

lib/storage: handle common case when the number of rows passed to flushRowsToInmemoryParts() doesnt exceed maxRawRowsPerShard 2024-02-23 01:12:18 +02:00

8669584e9f
lib/{storage,mergeset}: convert beffered items into searchable in-memory parts exactly once per the given flush interval
Previously the interval between item addition and its conversion to searchable in-memory part
could vary significantly because of too coarse per-second precision. Switch from fasttime.UnixTimestamp()
to time.Now().UnixMilli() for millisecond precision. It is OK to use time.Now() for tracking
the time when buffered items must be converted to searchable in-memory parts, since time.Now()
calls aren't located in hot paths.

Increase the flush interval for converting buffered samples to searchable in-memory parts
from one second to two seconds. This should reduce the number of blocks, which are needed
to be processed during high-frequency alerting queries. This, in turn, should reduce CPU usage.

While at it, hardcode the maximum size of rawRows shard to 8Mb, since this size gives the optimal
data ingestion pefromance according to load tests. This reduces memory usage and CPU usage on systems
with big amounts of RAM under high data ingestion rate.

lib/storage: do not pool rawRowsBlock when flushing rawRows to in-memory blocks
The pooled rawRowsBlock objects occupies big amounts of memory between flushes,
and the flushes are relatively rare. So it is better to don't use the pool
and to allocate rawRow blocks on demand. This should reduce the average
memory usage between flushes.

lib/storage: do not keep rawRows buffer across flush() calls
The buffer can be quite big under high ingestion rate (e.g. more than 100MB).
This leads to increased memory usage between buffer flushes.
So it is better to re-create the buffer on every flush in order to reduce memory usage
between buffer flushes.

app/vlselect: follow-up for 451d2abf50
- Consistently return the first `limit` log entries if the total size of found log entries doesn't exceed 1Mb.
  See app/vlselect/logsql/sort_writer.go . Previously random log entries could be returned with each request.
- Document the change at docs/VictoriaLogs/CHANGELOG.md
- Document the `limit` query arg at docs/VictoriaLogs/querying/README.md
- Make the change less intrusive.

lib/httpserver: do not close client connections every 2 minutes by default
Closing client connections every 2 minutes doesn't help load balancing -
this just leads to "jumpy" connections between multiple backend servers,

between the servers every 2 minutes.

It is still possible periodically closing client connections by specifying non-zero -http.connTimeout command-line flag.

lib/promscrape: use the standard net/http.Client instead of fasthttp.Client for scraping targets in non-streaming mode
While fasthttp.Client uses less CPU and RAM when scraping targets with small responses (up to 10K metrics),
it doesn't work well when scraping targets with big responses such as kube-state-metrics.
In this case it could use big amounts of additional memory comparing to net/http.Client,
since fasthttp.Client reads the full response in memory and then tries re-using the large buffer
for further scrapes.

Additionally, fasthttp.Client-based scraping had various issues with proxying, redirects
and scrape timeouts like the following ones:

- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1945
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5425
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2794
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1017

This should help reducing memory usage for the case when target returns big response
and this response is scraped by fasthttp.Client at first before switching to stream parsing mode
for subsequent scrapes. Now the switch to stream parsing mode is performed on the first scrape
after reading the response body in memory and noticing that its size exceeds the value passed
to -promscrape.minResponseSizeForStreamParse command-line flag.

lib/storage: do not check the limit for -search.maxUniqueTimeseries when performing /api/v1/labels and /api/v1/label/.../values requests
This limit has little sense for these APIs, since:

- Thses APIs frequently result in scanning of all the time series on the given time range.
  For example, if extra_filters={datacenter="some_dc"} .

- Users expect these APIs shouldn't hit the -search.maxUniqueTimeseries limit,
  which is intended for limiting resource usage at /api/v1/query and /api/v1/query_range requests.

Also limit the concurrency for /api/v1/labels, /api/v1/label/.../values
and /api/v1/series requests in order to limit the maximum memory usage and CPU usage for these API.
This limit shouldn't affect typical use cases for these APIs:

- Grafana dashboard load when dashboard labels should be loaded
- Auto-suggestion list load when editing the query in Grafana or vmui

lib/{mergeset,storage}: make background merge more responsive and scalable
- Maintain a separate worker pool per each part type (in-memory, file, big and small).
  Previously a shared pool was used for merging all the part types.
  A single merge worker could merge parts with mixed types at once. For example,
  it could merge simultaneously an in-memory part plus a big file part.
  Such a merge could take hours for big file part. During the duration of this merge
  the in-memory part was pinned in memory and couldn't be persisted to disk
  under the configured -inmemoryDataFlushInterval .

  Another common issue, which could happen when parts with mixed types are merged,
  is uncontrolled growth of in-memory parts or small parts when all the merge workers
  were busy with merging big files. Such growth could lead to significant performance
  degradataion for queries, since every query needs to check ever growing list of parts.
  This could also slow down the registration of new time series, since VictoriaMetrics
  searches for the internal series_id in the indexdb for every new time series.

  The third issue is graceful shutdown duration, which could be very long when a background
  merge is running on in-memory parts plus big file parts. This merge couldn't be interrupted,
  since it merges in-memory parts.

  A separate pool of merge workers per every part type elegantly resolves both issues:
  - In-memory parts are merged to file-based parts in a timely manner, since the maximum
    size of in-memory parts is limited.
  - Long-running merges for big parts do not block merges for in-memory parts and small parts.
  - Graceful shutdown duration is now limited by the time needed for flushing in-memory parts to files.
    Merging for file parts is instantly canceled on graceful shutdown now.

- Deprecate -smallMergeConcurrency command-line flag, since the new background merge algorithm
  should automatically self-tune according to the number of available CPU cores.

- Deprecate -finalMergeDelay command-line flag, since it wasn't working correctly.
  It is better to run forced merge when needed - https://docs.victoriametrics.com/#forced-merge

- Tune the number of shards for pending rows and items before the data goes to in-memory parts
  and becomes visible for search. This improves the maximum data ingestion rate and the maximum rate
  for registration of new time series. This should reduce the duration of data ingestion slowdown
  in VictoriaMetrics cluster on e.g. re-routing events, when some of vmstorage nodes become temporarily
  unavailable.

- Prevent from possible "sync: WaitGroup misuse" panic on graceful shutdown.

This is a follow-up for fa566c68a6 .

lib/mergeset: really limit the number of in-memory parts to 15
It has been appeared that the registration of new time series slows down linearly
with the number of indexdb parts, since VictoriaMetrics needs to check every indexdb part
when it searches for TSID by newly ingested metric name.

The number of in-memory parts grows when new time series are registered
at high rate. The number of in-memory parts grows faster on systems with big number
of CPU cores, because the mergeset maintains per-CPU buffers with newly added entries
for the indexdb, and every such entry is transformed eventually into a separate in-memory part.

The solution has been suggested in https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5212
by @misutoth - to limit the number of in-memory parts with buffered channel.
This solution is implemented in this commit. Additionally, this commit merges per-CPU parts
into a single part before adding it to the list of in-memory parts. This reduces CPU load
when searching for TSID by newly ingested metric name.

The https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5212 recommends setting the limit on the number
of in-memory parts to 100, but my internal testing shows that much lower limit 15 works with the same efficiency
on a system with 16 CPU cores while reducing memory usage for `indexdb/dataBlocks` cache by up to 50%.

lib/filestream: do not measure read / write duration from / to in-memory buffers
Measuring read / write duration from / to in-memory buffers has little sense,
since it will be always fast. It is better to measure read / write duration from / to
real files at vm_filestream_write_duration_seconds_total and vm_filestream_read_duration_seconds_total metrics.
This also reduces overhead on time.Now() and Histogram.UpdateDuration() calls
per each filestream.Reader.Read() and filestream.Writer.Write() call when the data is read / written from / to in-memory buffers.

Respect `0` value for `series_limit` param in `scrape_config`
even if global limit was set via `-promscrape.seriesLimitPerTarget`.
Previously, `0` value will be ignored in favor of `-promscrape.seriesLimitPerTarget`.

This behavior aligns with possibility to override `series_limit` value via

lib/storage: reduce the contention on dateMetricIDCache mutex when new time series are registered at high rate
The dateMetricIDCache puts recently registered (date, metricID) entries into mutable cache protected by the mutex.
The dateMetricIDCache.Has() checks for the entry in the mutable cache when it isn't found in the immutable cache.
Access to the mutable cache is protected by the mutex. This means this access is slow on systems with many CPU cores.
The mutabe cache was merged into immutable cache every 10 seconds in order to avoid slow access to mutable cache.
This means that ingestion of new time series to VictoriaMetrics could result in significant slowdown for up to 10 seconds
because of bottleneck at the mutex.

Fix this by merging the mutable cache into immutable cache after len(cacheItems) / 2
cache hits under the mutex, e.g. when the entry is found in the mutable cache.
This should automatically adjust intervals between merges depending on the addition rate
for new time series (aka churn rate):

- The interval will be much smaller than 10 seconds under high churn rate.
  This should reduce the mutex contention for mutable cache.
- The interval will be bigger than 10 seconds under low churn rate.
  This should reduce the uneeded work on merging of mutable cache into immutable cache.

Revert "lib/promscrape: do not store last scrape response when stale markers … (#5577)"
This reverts commit cfec258803.

Reason for revert: the original code already doesn't store the last scrape response when stale markers are disabled.
The scrapeWork.areIdenticalSeries() function always returns true is stale markers are disabled.
This prevents from storing the last response at scrapeWork.processScrapedData().

It looks like the reverted commit could also return back the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3660

* lib/promscrape/kubernetes: prevent from stopping groupWatcher when there are in-flight apiWatcher.mustStart() calls

groupWatcher is stopped if it has zero registered apiWatchers during 14 seconds.
But such a groupWatcher can be still in use if apiWatcher for `role: endpoints` or `role: endpointslice`
is being registered and the discovery of the associated `pod` and/or `service` objects takes longer
than 14 seconds - see the beginning of groupWatcher.startWatchersForRole() function for details.

Track the number of in-flight calls to apiWatcher.mustStart() and prevent from stopping the associated groupWatcher
if the number of in-flight calls is non-zero.

P.S. postponing the discovery of `pod` and/or `service` objects associated with `endpoints` or `endpointslice` roles
isn't the best solution, since it slows down initial discovery of `endpoints` and `endpointslice` targets.

* typo fix

  This shouldn't worsen code scalability too much on busy systems with many CPU cores,
  since the code executed under the lock is quite small and fast.
  This allows removing cloning of prefetchedMetricIDs struct every time
  new metric names are pre-fetched. This should reduce load on Go GC,
  since the cloning of uin64set.Set struct allocates many new objects.

lib/protoparser/opentelemetry: allow ingesting metrics without resource labels
Some clients may ingest samples via OpenTelemetry protocol without Resource labels.
Previously VictoriaMetrics was silently dropping such samples.

The commit 317834f876 added vm_protoparser_rows_dropped_total{type="opentelemetry",reason="resource_not_set"}
counter for tracking of such dropped samples. See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5459

It is better from usability PoV to accept such samples instead of dropping them and incrementing the corresponding counter.

e.g. if this target is scraped by other vmagent instances in the cluster.

Show also the reason why every target is dropped at /service-discovery page.
This should improve debuging why particular targets are dropped.

While at it, do not remove dropped targets from the list at /service-discovery page
until the total number of targets exceeds the limit passed to -promscrape.maxDroppedTargets .
Previously the list was cleaned up every 10 minutes from the entries, which weren't updated
for the last minute. This could complicate debugging of dropped targets.

lib/backup: consistently use path.Join() when constructing paths for s3, gs and azblob
E.g. replace `fs.Dir + filePath` with `path.Join(fs.Dir, filePath)`

The fs.Dir is guaranteed to end with slash - see Init() functions.
The filePath may start with slash. If it starts with slash, then `fs.Dir + filePath` constructs
an incorrect path with double slashes.
path.Join() properly substitutes duplicate slashes with a single slash in this case.

While at it, also substitute incorrect usage of filepath.Join() with path.Join()
for constructing paths to object storage systems, which expect forward slashes in paths.
filepath.Join() substittues forward slashes with backslashes on Windows, so this may break
creating or managing backups from Windows.

- Add Try* prefix to functions, which return bool result in order to improve readability and reduce the probability of missing check
  for the result returned from these functions.

- Call the adjustSampleValues() only once on input samples. Previously it was called on every attempt to flush data to peristent queue.

- Properly restore the initial state of WriteRequest passed to tryPushWriteRequest() before returning from this function
  after unsuccessful push to persistent queue. Previously a part of WriteRequest samples may be lost in such case.

- Add -remoteWrite.dropSamplesOnOverload command-line flag, which can be used for dropping incoming samples instead
  of returning 429 Too Many Requests error to the client when -remoteWrite.disableOnDiskQueue is set and the remote storage
  cannot keep up with the data ingestion rate.

- Add vmagent_remotewrite_samples_dropped_total metric, which counts the number of dropped samples.

- Add vmagent_remotewrite_push_failures_total metric, which counts the number of unsuccessful attempts to push
  data to persistent queue when -remoteWrite.disableOnDiskQueue is set.

- Remove vmagent_remotewrite_aggregation_metrics_dropped_total and vm_promscrape_push_samples_dropped_total metrics,
  because they are replaced with vmagent_remotewrite_samples_dropped_total metric.

- Update 'Disabling on-disk persistence' docs at docs/vmagent.md

app/vmagent: allow to disabled on-disk persistence (#5088)
* app/vmagent: allow to disabled on-disk queue
Previously, it wasn't possible to build data processing pipeline with a
chain of vmagents. In case when remoteWrite for the last vmagent in the
chain wasn't accessible, it persisted data only when it has enough disk
capacity. If disk queue is full, it started to silently drop ingested
metrics.

New flags allows to disable on-disk persistent and immediatly return an
error if remoteWrite is not accessible anymore. It blocks any writes and
notify client, that data ingestion isn't possible.

Main use case for this feature - use external queue such as kafka for
data persistence.

lib/protoparser: decrease import.maxLineLen from 100MB to 10MB (#5364)
Tests showed that importing a single line with 70MB size takes 5.3GiB
RSS memory for VictoriaMetrics single-node.
In the scenario when user exports and imports data from one VM to another,
it could possibly lead to OOM exception for destination VM.

Importing a single line with 16MB size taks 1.3GiB RSS memory.
Hence, the limit for `import.maxLineLen` was decreased from 100MB to 10MB
to improve reliability of VictoriaMetrics during imports.

lib/protoparser/promremotewrite: fall back to zstd decoding if Snappy-decoding fails (#5344)
This case is possible after the following steps:
1. vmagent successfully performed handshake with the -remoteWrite.url and the remote storage supports zstd-compressed data.
2. remote storage became unavailable or slow to ingest data, vmagent compressed the collected data into blocks with zstd and puts these blocks to persistent queue on disk.
3. vmagent restarts and the remote storage is unavailable during the handshake, then vmagent falls back to Snappy compression.
4. vmagent starts sending zstd-compressed data from persistent queue to the remote storage, while falsely advertizing it sends Snappy-compressed data.
5. The remote storage receives zstd-compressed data and fails unpacking it with Snappy.

The solution is the same as 12cd32fd75, just fall back to zstd decompression if Snappy decompression fails.

lib/regexutil: properly handle alternate regexps surrounded by .+ or .*
Previously the following regexps were improperly handled:

  .+foo|bar.+
  .*foo|bar.*

This could lead to unexpected regexp match results.

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5297

Thanks to @Haleygo for the initial attempt to fix the issue at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5308

lib/stringsutil: fix failing test (#5313)
We have failed test on master branch.

```
--- FAIL: TestFormatLogMessage (0.00s)
    logger_test.go:24: unexpected result; got
        "foo: abcde, \"foo bar baz\", xx"
        want
        "foo: a..e, \"f..z\", xx"
```
if failed because maxArgs maxLen <= 4 in the  `LimitStringLen` in that case we always will return the income string
but in the test we limit the maxLen by value 4
```
f("foo: %s, %q, %s", []interface{}{"abcde", fmt.Errorf("foo bar baz"), "xx"}, 4, `foo: a..e, "f..z", xx`)

lib/blockcache: do not cache entries, which were attempted to be accessed 1 or 2 times
Previously entries which were accessed only 1 time weren't cached.
It has been appeared that some rarely executed heavy queries may read indexdb block twice
in a row instead of once. There is no need in caching such a block then.
This change should eliminate cache size spikes for indexdb/dataBlocks when such heavy queries are executed.

Expose -blockcache.missesBeforeCaching command-line flag, which can be used for fine-tuning
the number of cache misses needed before storing the block in the caching.
