Lucene's experimental codecs (from the codecs module) do not provide
backwards compatibility and are free to change from release to
release. When they do change, they typically cannot in general read
older indices and the resulting exceptions look like index corruption.
So, we are removing built-in support for them to prevent applications
from choosing one and then seeing strange exceptions on upgrade.
Closes#7566Closes#7604
Enables filtering the actions on both sides - request and response. Also added a base class for filter implementations (cleans up filters that only need to filter one side)
Also refactored the filter & filter chain methods to more intuitive names
BlobContainer used to provide async APIs which are not used
internally. The implementation of these APIs are also not async
by nature and neither is any of the pluggable BlobContainers. This
commit simplifies the API to a simple input / output stream and
reduces the hierarchy of BlobContainer dramatically.
NOTE: This is a breaking change!
Closes#7551
Similar to the one in `TransportMessage`. Added the `ContextHolder` base class where both `TransportMessage` and `RestRequest` derive from
Now next to the known headers, the context is always copied over from the rest request to the transport request (when the injected client is used)
This adds the ability to the Term Vector API to generate term vectors for
artifical documents, that is for documents not present in the index. Following
a similar syntax to the Percolator API, a new 'doc' parameter is used, instead
of '_id', that specifies the document of interest. The parameters '_index' and
'_type' determine the mapping and therefore analyzers to apply to each value
field.
Closes#7530
The get, put and delete indexed script apis map to get, index and delete api and internally create those corresponding requests. We need to make sure that the original headers are handed over to the new request by passing the original request in the constructor when creating the new one.
Also streamlined the support for version and version_type in the REST layer since the parameters were not consistently parsed and set to the internal java API requests.
Modified the REST delete template and delete script actions to make use of a client instead of using the `ScriptService` directly.
Closes#7569
Removed CHM in favour of an OpenHashMap and synchronized accessor/mutator methods. Also, the context is now lazily inititialied (just like we do with the headers)
The useful headers are now stored into a `Set` instead of an array so we can easily deduplicate them. A set is also returned instead of an array by the `usefulHeaders` static getter.
Relates to #6513Closes#7590
Serialization if "index" setting for boost did not work since
the serialization was just true/false instead of valid options
"no"/"not_analyzed"/"analyzed".
closes#7557
`GetIndexedScriptRequest` now extends `ActionRequest` instead of `SingleShardOperationRequest`, as the index field that was provided with the previous base class is not needed (hardcoded).
Closes#7553
Aggregations are collection-wide statistics, which is incompatible with the
collection mode of search_type=SCAN since it doesn't collect all matches on
calls to the search API.
Close#7429
Aggregations are collection-wide statistics so they would always be the same.
In order to save CPU/bandwidth, we can just return them on the first page.
Same as #1642 but for aggregations.
After a node fails to respond to a ping correctly (master or node fault detection), they are removed from the cluster state through an UpdateTask. When a node is removed, a background task is scheduled using the generic threadpool to actually disconnect the node. However, in the case of temporary node failures (for example) it may be that the node was re-added by the time the task get executed, causing an untimely disconnect call. Disconnect is cheep and should be done during the UpdateTask.
Closes#7543
Enable lucene verification of checksums on segments before merging them.
This prevents corruption from existing segments from silently slipping into
newer merged segments.
