74ace9340d lib/storage: periodically reset prefetchedMetricIDs cache in order to limit its size under high churn rate 2021-07-07 10:59:39 +03:00

a846febc89 Revert "lib/uint64set: allow reusing bucket16 structs inside uint64set.Set via uint64set.Release method" 
This reverts commit 7c6d3981bf.

Reason for revert: high contention at bucket16Pool on systems with big number of CPU cores.
This slows down query processing significantly.

b805a675f3 lib/{mergeset,storage}: switch from sync.Pool to chan-based pool for inmemoryPart objects 
This should reduce memory usage on systems with big number of CPU cores,
since every inmemoryPart object occupies at least 64KB of memory and sync.Pool maintains
a separate pool inmemoryPart objects per each CPU core.

Though the new scheme for the pool worsens per-cpu cache locality, this should be amortized
by big sizes of inmemoryPart objects.

21abf487c3 lib/workingsetcache: properly update stats for requests and cache misses 
Previously the stats for cache misses could be improperly counted, because it had inflated cache misses
if the entry was missing in the curr cache, but was existing in the prev cache.

The same applies to cache requests - they were inflated if the entry was missing in the curr cache.

f12f97daa1 lib/{storage,mergeset}: increase cache timeout for data and index blocks from a minute to two minutes

bced9ee666 lib/{mergeset,storage}: reduce the maximum lifetime for cached indexdb and data blocks from 2 minutes to a minute 
This should reduce memory usage on a system with high number of active time series and a high churn rate.
One minute is enough for caching the blocks needed for repeated queries (e.g. alerting rules, recording rules and dashboard refreshes).

a22f37599b lib/storage: tune tag filters search logic 
Tune the logic according to the logs provided at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338#issuecomment-864293624

The previous logic had a race when multiple concurrent queries execute the same tag filter without prior stats.
This could result in incorrectly stored stats for such tag filter, which then could result in non-optimal sorting of tag filters
for further queries.

0efd37cec1 lib/{mergeset,storage}: reduce the number of fsync calls on data ingestion path on systems with many cpu cores 
VictoriaMetrics maintains a buffer per CPU core for the ingested data. These buffers are flushed to disk every second.
These buffers are flushed to disk in parallel starting from the commit 56b6b893ce .
This resulted in increased write disk IO usage on systems with many cpu cores
as described at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338#issuecomment-863046999 .

This commit merges the per-CPU buffers into bigger in-memory buffers before flushing them to disk.
This should reduce the rate of fsync syscalls and, consequently, the write disk IO on systems with many CPU cores.

This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338

b133de1e37 lib/storage: move deletedMetricIDs set from indexDB to Storage 
This makes consitent the list of deleted metricIDs when it is used from both the current indexDB and the previous indexDB (aka extDB).
This should fix the issue, which could lead to storing new samples under deleted metricIDs after indexDB rotation.
See more details at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1347#issuecomment-861232136 .

Thanks to @tangqipengleoo for the initial analysis and the pull request - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

This commit resolves the issue in more generic way compared to https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

The downside of the commit is the deletedMetricIDs set isn't cleaned from the metricIDs outside the retention. It needs app restart.
This should be OK in most cases.
