This changes the default ranking behaviour of single-term queries on numeric fields to use the usual Lucene TermQuery scoring logic rather than a constant-scoring wrapper.
Closes#10628
We have some duplication in TransportIndexAction/TransportShardBulkAction due
to the fact that we have totally different branches for INDEX and CREATE
operations. This commit tries to share the logic better between these two cases.
Adds support for calculating and sending diffs instead of full cluster state of the most frequently changing elements - cluster state, meta data and routing table.
Closes#6295
Whenever a transport client executes a request, it uses a built-in
RetryListener which tries to execute the request on another node.
However, if a connection error occurs, the onFailure() callback of
the listener is triggered, the netty I/O thread might still be used
to whatever failure has been added.
This commit offloads the onFailure handling to the generic thread pool.
the translog might be reused across engines which is currently a problem
in the design such that we have to allow calls to `close` more than once.
This moves the closed check for snapshot on the actual file to exit the loop.
Relates to #10807
If the translog is closed while a snapshot opertion is in progress
we must fail the snapshot operation otherwise we end up in an endless
loop.
Closes#10807
Internal: Change BigArrays to not extend AbstractComponent
In order to avoid the getLogger(getClass()) calls in the
AbstractComponent constructor.
Seems like BigArrays used to be a Singleton but it actually
no longer is one. Every time a SearchContext is created a
new BigArrays instance is created via the
withCircuitBreaking call.

In order to avoid the ``getLogger(getClass())`` calls in the

``withCircuitBreaking`` call.
Due to timing issues, mappings that are required to index a document might not
be available on the replica at indexing time. In that case the replica starts
listening to cluster state changes and re-parses the document until no dynamic
mappings updates are generated.
MergeContext currently exists to store conflicts, and providing
a mechanism to add dynamic fields. MergeResults store the same
conflicts. This change merges the two classes together, as well
as removes the MergeFlags construct.
This is in preparation for simplifying the callback structures
to dynamically add fields, which will require storing the mapping
updates in the results, instead of having a sneaky callback to
the DocumentMapper instance. It also just makes more sense that
the "results" of a merge are conflicts that occurred, along with
updates that may have occurred. For MergeFlags, any future needs
for parameterizing the merge (which seems unlikely) can just be
added directly to the MergeResults as simlulate is with this change.
This refactoring and cleanup is that each request handler ends up
implementing too many methods that can be provided when the request handler itself
is registered, including a prototype like class that can be used to instantiate
new request instances for streaming.

Today we have a lot of bloat in the IndexStore and related classes. THe IndexStore interface
is unneeded as we always subclass AbstractIndexStore and it hides circular dependencies
that are problematic when added. Guice proxies them if you have an interface which is bad in
general. This commit removes most of the bloat classes and unifies all the classes we have
into a single one since they all just structural and don't encode any functionality.
Refactor TransportShardReplicationOperationAction state management into clear separate Primary phase and Replication phase. The primary phase is responsible for routing the request to the node holding the primary, validating it and performing the operation on the primary. The Replication phase is responsible for sending the request to the replicas and managing their responses.
This also adds unit test infrastructure for this class, and some basic tests. We can extend later as we continue developing.
Closes#10749
This commit adds support for structural errors / failures / exceptions
on the elasticsearch REST layer. Exceptions are rendering with at least
a `type` and a `reason` corresponding to the exception name and the message.
Some expcetions like the ones associated with an index or a shard will have
additional information about the index the exception was triggered on or the
shard respectivly.
Each rendered response will also contain a list of root causes which is a list
of distinct shard level errors returned for the request. Root causes are the lowest
level elasticsearch exception found per shard response and are intended to be displayed
to the user to indicate the soruce of the exception.
Shard level response are by-default grouped by their type and reason to reduce the amount
of duplicates retunred. Yet, the same exception retunred from different indices will not be
grouped.
Closes#3303
Disabling doc values or trying to index hash values are not
correct uses of this the murmur3 field type, and just cause
problems. This disallows changing doc values or index options
for 2.0+.
