When ingesting samples with the same labels(duplicated samples or
samples with the same labels after `by` or `without` options). They
could register different entries for the same labelset in
LabelsCompressor.
For example, both index 99 and 100 can be assigned to label `foo=1` in
two concurrent pushes. Then due to differing label indexes in encoded
keys, the samples will appear as distinct in aggrState, resulting in
duplicated results after decompressing the label indexes.
fbde238cdc/lib/streamaggr/streamaggr.go (L933)
In this pull request, since we need to store `idxToLabel` first to
ensure the idx can be searched after `lc.labelToIdxStore`,
the `lc.idxToLabel` still could contain a duplicated entries
[100]="foo=1". But given the low likelihood of this issue and the size
of idxToLabel, it should be fine.
### Describe Your Changes
Introduce the `-search.maxDeleteSeries` flag that limits the number of
time series that can be deleted with a single
`/api/v1/admin/tsdb/delete_series` call.
Currently, any number can be deleted and if the number is big (millions)
then the operation may result in unaccounted CPU and memory usage spikes
which in some cases may result in OOM kill (see #7027). The flag limits
the number to 30k by default and the users may override it if needed at
the vmstorage start time.

Current doc is using per-url deduplication, and users might use this example
when they have more than 1 remoteWrite URL. Which would result into extra resource usage.
Changing the example to use global dedup, as it makes more sense.

Previous commit 201fd6de1e removed
trailing space trim from data read from file. But common practice is to
remove such trailing space. And it leaded to the authorization errors
for the major group of users.
In first place, this change must help to mitigate an issue with
kubernetes. When authorization information was read from Secret content.
Changes to the operator was made to mitigate such problem at commit
1cf64358c8
We could introduce later optional flag for VictoriaMetrics to disable
trim space behavior.

encoding.GetUint64s() returns uninitialized slice, which may contain arbitrary values.
So values in this slice must be reset to zero before using it for counting hits in `uniq` and `top` pipes.
This allows executing queries with `stats` pipe, which calculate multiple results with the same functions,
but with different `if (...)` conditions. For example:
_time:5m | count(), count() if (error)
Previously such queries couldn't be executed becasue automatically generated name for the second result
didn't include `if (error)`, so names for both results were identical - `count(*)`.
Now the following queries are equivalents:
_time:5s | sort by (_time)
_time:5s | order by (_time)
This is needed for convenience, since `order by` is commonly used in other query languages such as SQL.

Previously only logs inside the selected time range could be returned by stream_context pipe.
For example, the following query could return up to 10 surrounding logs only for the last 5 minutes,
while most users expect this query should return up to 10 surrounding logs without restrictions on the time range.
_time:5m panic | stream_context before 10
This enables the ability to implement stream context feature at VictoriaLogs web UI: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7063 .
Reduce memory usage when returning stream context over big log streams with millions of entries.
The new logic scans over all the log messages for the selected log stream, while keeping in memory only
the given number of surrounding logs. Previously all the logs for the given log stream on the selected time range
were loaded in memory before selecting the needed surrounding logs.
This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6730 .
Reduce the scan performance for big log streams by fetching only the requested fields. For example, the following
query should be executed much faster than before if logs contain many fields other than _stream, _msg and _time:
panic | stream_context after 30 | fields _stream, _msg, _time
Use local timezone of the host server in this case. The timezone can be overridden
with TZ environment variable if needed.
While at it, allow using whitespace instead of T as a delimiter between data and time
in the ingested _time field. For example, '2024-09-20 10:20:30' is now accepted
during data ingestion. This is valid ISO8601 format, which is used by some log shippers,
so it should be supported. This format is also known as SQL datetime format.
Also assume local time zone when time without timezone information is passed to querying APIs.
Previously such a time was parsed in UTC timezone. Add `Z` to the end of the time string
if the old behaviour is preferred.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6721
### Describe Your Changes
VictoriaLogs allows logs without `_msg` field or `_msg` field is empty.
This lead to incorrect search result. See:
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6785
This pull request search for non-empty `_msg` field before log entry is
added to `LogRows`.
New counter `vl_rows_dropped_total{reason="msg_not_exist"}` is
introduced.
Example log output:
```
2024-09-23T02:33:19.719Z warn app/vlinsert/insertutils/common_params.go:189 dropping log line without _msg field; [{@timestamp 2024-09-18T13:42:16.600000000Z} {Attributes.array.attribute ["many","values"]} {Attributes.boolean.attribute true} {Attributes.double.attribute 637.704} {Attributes.int.attribute 10} {Attributes.map.attribute.some.map.key some value} {Attributes.string.attribute some string} {Body Example ddddddddddlog record} {Resource.service.name my.service} {Scope.my.scope.attribute some scope attribute} {Scope.name my.library} {Scope.version 1.0.0} {SeverityNumber 10} {SeverityText Information} {SpanId eee19b7ec3c1b174} {TraceFlags 0} {TraceId 5b8efff798038103d269b633813fc60c}]
