The current logic for doing recovery from a source to a target shourd is tightly coupled with the underlying network pipes. This changes decouple the two, making it easier to add unit tests for shard recovery that doesn't involve the node and network environment.
On top that, RecoveryTarget is renamed to RecoveryTargetService leaving space to renaming RecoveryStatus to RecoveryTarget (and thus avoid the confusion we have today with RecoveryState).
Correspondingly RecoverySource is renamed to RecoverySourceService.
Closes#16605
The `keyword` field is intended to replace `not_analyzed` string fields. It is
indexed and has doc values by default, and doesn't support enabling term
vectors.
Although it doesn't support setting an analyzer for now, there are plans for
it to support basic normalization in the future such as case folding.
2.x has show so far that running with security manager is the way to go.
This commit make this non-optional. Users that need to pass their own rules
can still do this via the system configuration for the security manager. They
can even opt out of all security that way.
This commit moves IndicesRequestCache into o.e.indics and makes all API in this
class package private. All references to SearchReqeust, SearchContext etc. have been factored
out and relevant glue code has been added to IndicesService. The IndicesRequestCache is not a
simple class without any hard dependencies on ThreadPool nor SearchService or IndexShard. This now
allows to add unittests.
This commit also removes two settings `indices.requests.cache.clean_interval` and `indices.fielddata.cache.clean_interval`
in favor of `indices.cache.clean_interval` which cleans both caches.
Some bw incompatible setting changes:
http.netty.http.blocking_server -> http.tcp.blocking_server
http.netty.host (removed, we just have http.host)
http.netty.bind_host (removed, we just have http.bind_host)
http.netty.publish_host (removed, we just have http.publish_host)
http.netty.tcp_no_delay -> http.tcp.no_delay
http.netty.tcp_keep_alive -> http.tcp.keep_alive
http.netty.reuse_address -> http.txp.reuse_address
http.netty.tcp_send_buffer_size -> http.tcp.send_buffer_size
http.netty.tcp_receive_buffer_size -> http.tcp.receive_buffer_size
Closes#16531
this is a minor cleanup that detaches `IndicesRequestCache` and `IndicesQueryCache`
from guice and moves it into `IndicesService`. It also decouples the `IndexShard` and `IndexService`
from these caches which are unnecessary dependencies.
QueryBuilders today do all their heavy lifting in toQuery() which
can be too late for several operations. For instance if we want to fetch geo shapes
on the coordinating node we need to do all this before we create the actual lucene query
which happens on the shard itself. Also optimizations for request caching need to be done
to the query builder rather than the query which then in-turn needs to be serialized again.
This commit adds the basic infrastructure for query rewriting and moves the heavy lifting into
the rewrite method for the following queries:
* `WrapperQueryBuilder`
* `GeoShapeQueryBuilder`
* `TermsQueryBuilder`
* `TemplateQueryBuilder`
Other queries like `MoreLikeThisQueryBuilder` still need to be fixed / converted. The nice
sideeffect of this is that queries like template queries will now also match the request cache
if their non-template equivalent has been cached befoore. In the future this will allow to
add optimizataion like rewriting time-based queries into primitives like `match_all_docs` or `match_no_docs`
based on the currents shards bounds. This is especially appealing for indices that are read-only ie. never change.
In the testCanFetchIndexStatus the task check can occur before the indexing process is started making the test to fail. This commit adds an additional lock to make sure we check tasks only after at least one of the tasks is registered.
This groups like projects together which is nice. It creates two weirdly
named projects:
1. buildSrc - its still just called buildSrc and it doesn't match. I don't
see why we import it into Eclipse anyway. Its groovy and easier to just edit
in vim or whatever.
2. elasticsearch - this is the name of the root project. It's also not
particularly useful to import into eclipse but we've always named it this way
and the name ':' was even more confusing so we just kept the name.
This commit removes bootstrap support for Java Service Wrapper. The
implementation of this has been moved to its own repository where it was
deprecated, does not work with Elasticsearch 2.x, and is untested and
therefore unmaintained.
Closes#16580
This commit handles the scenario where a replication action fails on a
replica shard, the primary shard attempts to fail the replica shard
but the primary shard is notified of demotion by the master. In this
scenario, the demoted primary shard must be failed, and then the
request rerouted again to the new primary shard.
Closes#16415, closes#14252
