Invocation counts can be used to help judge the selectivity of individual query components in the context of the entire query. E.g. a query may not look selective when run by itself (matches most of the index), but when run in context of a full search request, is evaluated only rarely due to execution order
Since this is modifying the base timing class, it'll enrich both query and agg profiles (as well as future profile results)
Today `node.mode` and `node.local` serve almost the same purpose, they
are a shortcut for `discovery.type` and `transport.type`. If `node.local: true`
or `node.mode: local` is set elasticsearch will start in _local_ mode which means
only nodes within the same JVM are discovered and a non-network based transport
is used. The _local_ mode it only really used in tests or if nodes are embedded.
For both, embedding and tests explicit configuration via `discovery.type` and `transport.type`
should be preferred.
This change removes all the usage of these settings and by-default doesn't
configure a default transport implemenation since netty is now a module. Yet, to make
the user expericence flawless, plugins or modules can set a `http.type.default` and
`transport.type.default`. Plugins set this via `PluginService#additionalSettings()`
which enforces _set-once_ which prevents node startup if set multiple times. This means
that our distributions will just startup with netty transport since it's packaged as a
module unless `transport.type` or `http.transport.type` is explicitly set.
This change also found a bunch of bugs since several NamedWriteables were not registered if a
transport client is used. Now that we don't rely on the `node.mode` leniency which is inherited
instead of using explicit settings, `TransportClient` uses `AssertingLocalTransport` which detects these problems since it serializes all messages.
Closes#16234
The Java API supports this while mostly used for tests it can also be useful in
production environments. For instance if something is automated like a settings change
and we execute some health right after it the settings update might have some consequences
like a reroute which hasn't been fully applied since the preconditions are not fulfilled yet.
For instance if not all shards started the settings update is applied but the reroute won't move
currently initializing shards like in the shrink API test. Sure this could be done by waiting for
green before but if the cluster moves shards due to some side-effects waiting for all events is
still useful. I also took the chance to add unittests to Priority.java
Closes#19419
This adds an extra method, registerWithDeprecatedHandler, to register both a normal handler and a deprecated handler at the same time. This helps with renaming methods as opposed to _just_ deprecated methods.
Today we assert that the tmp files are present but if the recovery
was canceled this might not be the case while still a valid state.
This chance only throws the AssertionError if the recovery is still active.
This moves all netty related code into modules/transport-netty the module is build as a zip file as well as a JAR to serve as a dependency for transport client. For the time being this is required otherwise we have no network based impl. for transport client users. This might be subject to change given that we move forward http client.
* Clean up the generics around significant terms aggregation results
* Reduce code duplicated between `SignificantLongTerms` and
`SignificantStringTerms` by creating `InternalMappedSignificantTerms`
and moving common things there where possible.
* Migrate to `NamedWriteable`
* Line length fixes while I was there
This commit removes support for properties syntax and config files:
- removed support for elasticsearch.properties
- removed support for logging.properties
- removed support for properties content detection in REST APIs
- removed support for properties content detection in Java API

Some tests still start http implicitly or miss configuring the transport clients correctly.
This commit fixes all remaining tests and adds a depdenceny to `transport-netty` from
`qa/smoke-test-http` and `modules/reindex` since they need an http server running on the nodes.
This also moves all required permissions for netty into it's module and out of core.
If a nested, has_child or has_parent query's inner query gets rewritten then the InnerHitBuilder should use that rewritten form too, otherwise this can cause exceptions in a later phase.
Also fixes a bug that HasChildQueryBuilder's rewrite method overwrites max_children with min_children value.
Closes#19353
That exception is currently serialized as its current base class IllegalStateException which confuses code supposed to deal with the stepping down of a master. This is an important exception and we should be able to serialize it correctly. This commit fixes it by moving the exception to inherit from ElasticsearchException and properly register it.
As a bonus I adapted CapturingTransport to properly simulate serialized exceptions.
Switches most search behavior extensions from push (`onModule(SearchModule)`)
to pull (`implements SearchPlugin`). This effort in general gives plugin
authors a much cleaner view of how to extend Elasticsearch and starts to
set up portions of Elasticsearch as "the plugin API". This commit in
particular does that for search-time behavior like customized suggesters,
highlighters, score functions, and significance heuristics.
It also switches most such customization to being done at search module
construction time which is much, much easier to reason about from a testing
perspective. It also helps significantly in the process of de-guice-ing
Elasticsearch's startup.
There are at least two major search time extensions that aren't covered in
this commit that will simply have to wait for the next commit on the topic
because this one has already grown large: custom aggregations and custom
queries. These will likely live in the same SearchPlugin interface as well.
This change adds a createComponents() method to Plugin implementations
which they can use to return already constructed componenents/services.
Eventually this should be just services ("components" don't really do
anything), but for now it allows any object so that preconstructed
instances by plugins can still be bound to guice. Over time we should
add basic services as arguments to this method, but for now I have left
it empty so as to not presume what is a necessary service.
this commit moves the most of the http related integ tests out into it's own
`qa/smoke-test-http` project where most of the test can run against the external cluster.
Today when a node is removed the cluster (it leaves or it fails), we
submit a cluster state update task. These cluster state update tasks are
processed serially on the master. When nodes are removed en masse (e.g.,
a rack is taken down or otherwise becomes unavailable), the master will
be slow to process these failures because of the resulting reroutes and
publishing of each subsequent cluster state. We improve this in this
commit by processing the node removals using the cluster state update
task batch processing framework.

Today we have a bunch of tests that use netty transport for several reasons
these tests use it because they need to run some tcp based transport. Yet, this
couples our tests tightly to the netty implementation which should be tested on it's own.
This change adds a plain socket based blocking TcpTransport implementation that is used by
default in tests if local transport is suppressed or if network is selected.
It also adds another tcp network implementation as a showcase how the interface works.
Lucene IndexWriter asserts on files existing on the filesystem but
some tests throw IOException explicitly on those operatiosn such that
some tests trip asserts. We had this before on InternalEngine#ctor
and added some logic there to catch only a specific assertions based
on some excepition stack analysis. This change applies the same logic
to the IndexWriter#commit part of the engine since it can hit the same
issue.
This also fixes a self-suppression issue in Store.java.
