=== Logstash 7.9.0 Release Notes
|
||||
|
||||
==== New features and enhancements
|
||||
|
||||
===== ECS support in Elasticsearch output plugin
|
||||
|
||||
This release is the first step toward Elastic Common Schema (ECS) support in
|
||||
{ls}. With 7.9, you can configure the <<plugins-outputs-elasticsearch,{es}
|
||||
output plugin>> to manage index templates that are compatible with the
|
||||
{ecs-ref}[Elastic Common Schema (ECS)]. The
|
||||
<<plugins-outputs-elasticsearch-ecs_compatibility,ECS compatibility setting>>
|
||||
in the {es} output plugin makes this possible.
|
||||
|
||||
See
|
||||
{logstash-ref}/plugins-outputs-elasticsearch.html#_compatibility_with_the_elastic_common_schema_ecs[Compatibility with the Elastic Common Schema (ECS)]
|
||||
in the {es} output plugin docs for more information.
|
||||
|
||||
===== Expanded API key support
|
||||
|
||||
With this release, we've continued expanding support for {es} API keys. Support
|
||||
for API keys in the <<plugins-outputs-elasticsearch,{es} output plugin>> arrived
|
||||
in {ls} 7.8.0. {ls} 7.9.0 introduces support for {es} API keys in the
|
||||
<<plugins-inputs-elasticsearch,{es} input plugin>>, the
|
||||
<<plugins-filters-elasticsearch,{es} filter plugin>>, and {ls}
|
||||
<<ls-api-key-monitor,monitoring>> and <<ls-api-key-man,management>>.
|
||||
|
||||
Check out <<ls-api-keys>> for more information about using API keys with {ls}
|
||||
and {es}.
|
||||
Implementation details are in https://github.com/elastic/logstash/pull/11953[#11953].
|
||||
|
||||
===== ARM64 support (experimental)
|
||||
|
||||
{ls} runs on arm machines! We have tested {ls} against arm64, and we are looking
|
||||
to make docker and other images available soon.
|
||||
|
||||
ARM artifacts are not yet supported for production, and we’re offering them as
|
||||
"experimental" to early adopters.
|
||||
|
||||
===== Improved support in App Search output
|
||||
|
||||
We replaced the deprecated Java client library for the
|
||||
<<plugins-outputs-elastic_app_search,Elastic App Search output plugin>> with the
|
||||
Ruby client library, and expanded integration testing. These changes provide a
|
||||
foundation for expanding App Search integration and quality assurance in future
|
||||
releases.
|
||||
|
||||
===== Improvements to persistent queue (PQ)
|
||||
|
||||
We've enhanced persistent queues to better manage exceptions and error handling
|
||||
which could sometimes result in a `LockException` when the queue file lock was
|
||||
not properly released. Under some conditions, a complex pipeline that is slower
|
||||
to initialize could be recreated when it was not done initializing, causing a
|
||||
`LockException`. Implementation details are in https://github.com/elastic/logstash/pull/12023[#12023].
|
||||
|
||||
These changes result in better stability of persistent queues.
|
||||
|
||||
===== Improvements to pipeline workers error handling
|
||||
|
||||
Worker threads were not correctly monitored for a worker loop exception
|
||||
resulting in a complete logstash crash upon any exception even when multiple
|
||||
pipelines are running. Now only the failed pipeline is terminated. If pipeline
|
||||
reloading is enabled, you can edit the config and have the failed pipeline
|
||||
reloaded.
|
||||
Implementation details are in
|
||||
https://github.com/elastic/logstash/pull/12019[#12019] and
|
||||
https://github.com/elastic/logstash/pull/12038[#12038].
|
||||
|
||||
===== Performance improvement on startup and pipeline restarts
|
||||
|
||||
This release contains several optimizations to pipeline compilation, an
|
||||
essential step of the pipeline initialization process. These changes
|
||||
significantly improve startup and pipeline-restart performance for complex
|
||||
pipelines.
|
||||
(For technical details, check out this PR: https://github.com/elastic/logstash/pull/12060[#12060].)
|
||||
|
||||
From our tests in three different pipelines with eight workers each, we have
|
||||
seen times decrease from 9 - 28 minutes to around 1 minute.
|
||||
|
||||
To aid the development of pipelines, especially the performance impact of
|
||||
compilation, Logstash now reports the time taken to compile each pipeline as a
|
||||
log entry such as:
|
||||
|
||||
[source,sh]
