Introduce minimal thread scheduler as a base class for `ThreadPool`. Such a class can be used from the `BulkProcessor` to schedule retries and the flush task. This allows to remove the `ThreadPool` dependency from `BulkProcessor`, which requires to provide settings that contain `node.name` and also needed log4j for logging. Instead, it needs now a `Scheduler` that is much lighter and gets automatically created and shut down on close.
Closes#26028
The current "Building Queries" and "Building Aggregations" pages are
located under the "Supported Apis" section because they are linked to
the "Search API" page.
It should instead be in a dedicated section: this commit adds a new
"Using Java Builders" section and renames few filenames in favor of
more meaningful names.
By making RestHighLevelClient Closeable, its close method will close the internal low-level REST client instance by default, which simplifies the way most users interact with the high-level client.
Its constructor accepts now a RestClientBuilder, which clarifies that the low-level REST client is internally created and managed.
It is still possible to provide an already built `RestClient` instance, but that can only be done by subclassing `RestHighLevelClient` and calling the protected constructor that accepts a `RestClient`. In such case a consumer has also to be provided, which controls what has to be done when the high-level client gets done.
Closes#26086
When using the High Level Rest Client 6.0.0-beta1, we are missing some transitive dependencies for Lucene as Lucene 7 has not been released yet. See the following `pom.xml`:
```xml
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-client</artifactId>
<version>6.0.0-beta1</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>6.0.0-beta1</version>
</dependency>
```
It gives:
```
[ERROR] Failed to execute goal on project fscrawler: Could not resolve dependencies for project fr.pilato.elasticsearch.crawler:fscrawler:jar:2.4-SNAPSHOT: The following artifacts could not be resolved: org.apache.lucene:lucene-analyzers-common:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-backward-codecs:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-grouping:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-highlighter:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-join:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-memory:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-misc:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-queries:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-queryparser:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-sandbox:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-spatial:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-spatial-extras:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-spatial3d:jar:7.0.0-snapshot-00142c9, org.apache.lucene:lucene-suggest:jar:7.0.0-snapshot-00142c9: Failure to find org.apache.lucene:lucene-analyzers-common:jar:7.0.0-snapshot-00142c9 in https://artifacts.elastic.co/maven/ was cached in the local repository, resolution will not be reattempted until the update interval of elastic-download-service has elapsed or updates are forced -
```
We need to add some temporary documentation on how to add the missing repository to a gradle or maven project:
```xml
<repository>
<id>elastic-lucene-snapshots</id>
<name>Elastic Lucene Snapshots</name>
<url>http://s3.amazonaws.com/download.elasticsearch.org/lucenesnapshots/00142c9</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>false</enabled></snapshots>
</repository>
```
This also applies to the transport client.
Closes#26106.
We publish javadocs to artifacts.elastic.co (and snapshots.elastic.co) for a while. This commit adds the link to them to the transport client, low level REST client, sniffer and high level REST client pages.
Closes#23761
The alpha2 docs is built out of master which may make users think that the high level client was already released as part of alpha2 which it was not. This note should clarify that the client will be released with 6.0.0-beta1
This adds a section about how to add aggregations to the SearchSourceBuilder and how
to retrieve them from a SearchRepsonse to the documentation for the high level rest client.
It was brought up that our current client artifacts have generic names like 'rest' that may cause conflicts with other artifacts.
This commit renames:
- rest -> elasticsearch-rest-client
- sniffer -> elasticsearch-rest-client-sniffer
- rest-high-level -> elasticsearch-rest-high-level-client
A couple of small changes are also preparing the high level client for its first release.
Closes#20248
This commit converts the low level client and high level client chapters into two parts, which allows each high level client supported api to be on a separate page and show up in the index on the right.
The REST Client is split into 2 parts:
* Low level
* High level
The High level client has a main common section and the document delete API documentation as a start.
