- Properly decode protobuf-encoded Loki request if it has no Content-Encoding header.
Protobuf Loki message is snappy-encoded by default, so snappy decoding must be used
when Content-Encoding header is missing.
- Return back the previous signatures of parseJSONRequest and parseProtobufRequest functions.
This eliminates the churn in tests for these functions. This also fixes broken
benchmarks BenchmarkParseJSONRequest and BenchmarkParseProtobufRequest, which consume
the whole request body on the first iteration and do nothing on subsequent iterations.
- Put the CHANGELOG entries into correct places, since they were incorrectly put into already released
versions of VictoriaMetrics and VictoriaLogs.
- Add support for reading zstd-compressed data ingestion requests into the remaining protocols
at VictoriaLogs and VictoriaMetrics.
- Remove the `encoding` arg from PutUncompressedReader() - it has enough information about
the passed reader arg in order to properly deal with it.
- Add ReadUncompressedData to lib/protoparser/common for reading uncompressed data from the reader until EOF.
This allows removing repeated code across request-based protocol parsers without streaming mode.
- Consistently limit data ingestion request sizes, which can be read by ReadUncompressedData function.
Previously this wasn't the case for all the supported protocols.

The `ignore_fields` HTTTP query args can contain prefixes ending with '*'.
For example, `ignore_fields=foo.*,bar` skips all the fields starting with `foo.`
during data ingestion.
Loki doesn't support well high-cardinality log fields (e.g. fields with big number of unique values).
That's why Promtail, Grafana Agent and Grafana Alloy encode such fields into a JSON and push them
as a plaintext log message to the remote storage. This isn't an efficient way to store high-cardinality
log fields in VictoriaLogs, since it is optimized for storing and querying such fields when they are stored
distinctly as a regular log fields according to VictoriaLogs data model ( https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model ).
This commit enables automatic parsing of JSON-encoded log fields at plaintext log message received over Loki protocol
and storing them as a separate log fields. This should improve data compression ratio and reduce disk space usage.
This should also improve query performance when the parsed log fields are used in queries for filtering and aggregation.
The old behaviour can be restored by passing -loki.disableMessageParsing command-line flag to VictoriaLogs.

This chapter is needed for referring from Github issues when CPU or memory profiles are needed to be collected
in order to investigate issues with high CPU and/or RAM usage at VictoriaLogs.
- The --delete option is needed to be passed to rsync during backups,
Since otherwise the backup may contain superfluous files after the second run of rsync,
because these files can be already removed at the source because of background merge
- the --delete option is needed when restoring from backup in order to remove superfluous files
from the destination directory. Otherwise these files may lead to inconsistent data at VictoriaLogs.
In this case the _msg field is set to the value specified in the -defaultMsgValue command-line flag.
This should simplify first-time migration to VictoriaLogs from other systems.
### Describe Your Changes
Fixed VictoriaLogs HA examples references in docs

It has been appeared that there are VictoriaMetrics users, who rely on the fact that
VictoriaMetrics components were closing incoming connections to -httpListenAddr every 2 minutes
by default. So let's return back this value by default in order to fix the breaking change
made at d8c1db7953 .
