Update the PerFieldFormatSupplier so that new standard indices use the
Lucene101PostingsFormat instead of the current default ES812PostingsFormat.
Currently, use of the new codec is gated behind a feature flag.
This feature flag controls whether synthetic recovery source is enabled by default when the source mode is synthetic.
The synthetic recovery source feature itself is already available via the index.recovery.use_synthetic_source index setting and can be enabled by anyone using synthetic source.
The default value of index.recovery.use_synthetic_source setting defaults to true when index.mapping.source.mode is enabled. The index.mapping.source.mode default to true if index.mode is logsdb or time_series.
In other words, with this change synthetic recovery source will be enabled by default for logsdb and tsdb.
Closes#116726
This PR extends the work done in #121751 by enabling a sparse doc values index for the @timestamp field in LogsDB.
Similar to the previous PR, the setting index.mapping.use_doc_values_skipper will override the index mapping parameter when all of the following conditions are met:
* The index mode is LogsDB.
* The field name is @timestamp.
* Index sorting is configured on @timestamp (regardless of whether it is a primary sort field or not).
* Doc values are enabled.
This ensures that only one index structure is defined on the @timestamp field:
* If the conditions above are met, the inverted index is replaced with a sparse doc values index.
* This prevents both the inverted index and sparse doc values index from being enabled together, reducing unnecessary storage overhead.
This change aligns with our goal of optimizing LogsDB for storage efficiency while possibly maintaining reasonable query latency performance. It will enable us to run benchmarks and evaluate the impact of sparse indexing on the @timestamp field as well.
We experimented with using synthetic source for recovery and observed quite positive impact
on indexing throughput by means of our nightly Rally benchmarks. As a result, here we enable
it by default when synthetic source is used. To be more precise, if `index.mapping.source.mode`
setting is `synthetic` we enable recovery source by means of synthetic source.
Moreover, enabling synthetic source recovery is done behind a feature flag. That would allow us
to enable it in snapshot builds which in turn will allow us to see performance results in Rally nightly
benchmarks.
To simplify the migration away from version based skip checks in YAML specs,
this PR adds a synthetic version feature `gte_vX.Y.Z` for any version at or before 8.14.0.
New test specs for 8.14 or later are expected to use respective new cluster features,
or a test-only feature supplied via ESRestTestCase#createAdditionalFeatureSpecifications
if sufficient.
* Make the ShardsAvailabilityIndicator pluggable
This commit makes the `ShardsAvailabilityIndicator` pluggable. It currently provides the existing `ShardsAvailabilityHealthIndicatorService` (without moving it) for the `shards_availability` output in the health report API.
This will allow us in the future to provide a separate `shards_availability` plugin to override the way that health is reported for shards.
This makes the data stream lifecycle generally available. This will allow
data streams to take advantage of a native simplified and resilient
lifecycle implementation.
This introduces an endpoint to reset the desired balance.
It could be used if computed balance diverged from the actual one a lot
to start a new computation from the current state.
This commit adds a new test framework for configuring and orchestrating
test clusters for both Java and YAML REST testing. This will eventually
replace the existing "test-clusters" Gradle plugin and the build-time
cluster orchestration.
This adds a new sampling aggregation that performs a background sampling over all documents in an index.
The syntax is as follows:
```
{
"aggregations": {
"sampling": {
"random_sampler": {
"probability": 0.1
},
"aggs": {
"price_percentiles": {
"percentiles": {
"field": "taxful_total_price"
}
}
}
}
}
}
```
This aggregation provides fast random sampling over the entire document set in order to speed up costly aggregations.
Testing this over a variety of aggregations and data sets, the median speed up when sampling at `0.001` over millions of documents is around 70X speed improvement.
Relative error rate does rely on the size of the data and the aggregation kind. Here are some typically expected numbers when sampling over 10s of millions of documents. `p` is the configured probability and `n` is the number of documents matched by your provided filter query.
Lucene issues that resulted in elasticsearch changes:
LUCENE-9820 Separate logic for reading the BKD index from logic to intersecting it.
LUCENE-10377: Replace 'sortPos' with 'enableSkipping' in SortField.getComparator()
LUCENE-10301: make the test-framework a proper module by moving all test
classes to org.apache.lucene.tests
LUCENE-10300: rewrite how resources are read in ukrainian morfologik analyzer:
LUCENE-10054 Make HnswGraph hierarchical
Make `index.time_series.start_time` and `index.time_series.end_time` settings as required settings in tsdb indices.
It will change many tests, among which a time_series index is created, and it will add the `index.time_series.start_time` and `index.time_series.end_time` settings
* Route documents to the correct shards in tsdb
This causes elasticsearch to land documents from the same time series on
the same shard. It does so by adding a new index setting `routing_path`
which must be set when an index is in `mode: time_series` and may not be
set outside of that mode. That setting contains a list of patterns to
extract from the `_source` document that are hashed into the routing
value.

We do want to reject these documents but let's sae that for a follow up

This adds a setting to enable time series mode that is hidden by the
`es.index_mode_feature_flag_registered` feature flag. All it does right
now is make sure you haven't configured index sorting and partitioning.
This gives us a place to "hang" all of our further work on time series
mode.
Time series mode will entirely take over index sorting. We don't believe
you'll ever be able to configure sorting yourself when you are in time
series mode. We don't expect time series mode to support index
partitioning when we first build it but we'd like to get there.
Extract usage of internal API from TestClustersPlugin and PluginBuildPlugin and related plugins and build logic
This includes a refactoring of ElasticsearchDistribution to handle types
better in a way we can differentiate between supported Elasticsearch
Distribution types supported in TestCkustersPlugin and types only supported
in internal plugins.
It also introduces a set of internal versions of public plugins.
As part of this we also generate the plugin descriptors now.
As a follow up on this we can actually move these public used classes into
an extra project (declared as included build)
We keep LoggedExec and VersionProperties effectively public And workaround for RestTestBase
* Warn users if security is implicitly disabled
Elasticsearch has security features implicitly disabled by default for
Basic and Trial licenses, unless explicitly set in the configuration
file.
This may be good for onboarding, but it also lead to unintended insecure
clusters.
This change introduces clear warnings when security features are
implicitly disabled.
- a warning header in each REST response if security is implicitly
disabled;
- a log message during cluster boot.
As per the new licensing change for Elasticsearch and Kibana this commit
moves existing Apache 2.0 licensed source code to the new dual license
SSPL+Elastic license 2.0. In addition, existing x-pack code now uses
the new version 2.0 of the Elastic license. Full changes include:
- Updating LICENSE and NOTICE files throughout the code base, as well
as those packaged in our published artifacts
- Update IDE integration to now use the new license header on newly
created source files
- Remove references to the "OSS" distribution from our documentation
- Update build time verification checks to no longer allow Apache 2.0
license header in Elasticsearch source code
- Replace all existing Apache 2.0 license headers for non-xpack code
with updated header (vendored code with Apache 2.0 headers obviously
remains the same).
- Replace all Elastic license 1.0 headers with new 2.0 header in xpack.
This ports the majority of the rest integ tests tasks to use the task avoidance api.
- There are some edge cases left that we need to investigate, but we can do that separately.
