0.13.0
Release Notes:
Breaking changes:
- Change single operation shard hashing to only use id, and not id and type (#472)
- Create specific
data location for indices (move from work) (#473)
- Mapping: Rename _attributes to _meta (#518)
New features:
- Write Consistency Level for index/delete/delete_by_query/bulk with one/quorum/all. Defaults to quorum. (#444)
- When on linux, force it not to swap elasticsearch process (jvm) (#464)
- API: Allow to control document shard routing, and search shard routing (#470)
- Indices API: Add open and close index (#447)
- Mapper:
- Ip Type Support (ipv4), auto detection with dynamic mapping (#461)
- Add
path_match for full object navigation path matching (#476)
- An analyzer mapper allowing to control the index analyzer of a document based on a document field (#485)
- Query DSL: Allow to provide pattern field names when using query_string query (#511)
- Routing:
- When specify in the mapping _routing required, a delete without explicit routing value should automatically be broadcasted to all shards (#522)
- Allow to define
path on the _routing mapping, to automatically extract the routing from it (#524)
- Transport Thrift: Upgrade to thrift 0.5.0 (#457)
Enhancements:
- Reduce multiple indices overhead, don’t create Indices data on nodes that don’t hold any shard for an index (#441)
- Improve performance when searching across multiple types (#478)
- Add an option to display max_open_files, by setting -Des.max-open-files to
true (#483)
- Cluster health API should return RED status (on applicable levels) when an index has not recovered from the gateway (#507)
- Analysis: Allow to alias analyzers (#486)
- Fs Gateway: Add (native) file lock to ensure two nodes in a split brain are not updating same gateway (#481)
- Get Action: Allow to pass refresh forcing getting latest (#488)
- Histogram Facet: Allow to define a key field and value script (#517)
- Index: Move compound format setting to
index.compound_format (old setting still supported) (#463)
- Index Merge: Change default
index.merge.scheduler.max_thread_count from @ to be adaptive based on processor count (#469)
- Mapper:
- Store the routing (if provided) under a
_routing field (#515)
date type to also allow providing values in numeric (milliseconds since epoch) (#516)
- Mapping: add threshold to _source field compression (#506)
- Query DSL:
- Add
exists and missing filters to filter documents where a field either has a value or not in them. (#445)
- Query String missing and exists syntax (#446)
term, term, prefix, and range filter are now weakly cached, for more strong caching, set _cache to true. (#450)constant_score and filtered queries cache filters by default, remove it (#449)term filter to have _cache set to true by default (#453)- Revert back and have range, terms, and prefix filter _cache set to true (#456)
- Add
field_masking_span query (#471)
- Allow to control (globally) the max clause count for
bool query (defaults to 1024) (#482)
- Rivers: Add a _status doc for each river (#468)
- Routing: Allow to specify on the
_routing mapping that its required, and fail index operations that do not provide one (#520)
- Search: Change default operation threading to
thread_per_shard from single_thread (#455)
- Cluster Health API: add number of data nodes (commit)
Bug fixes:
- “geo_distance” parsing bugs (#454)
- On full cluster restart, replicas transaction logs are not getting cleaned (#465)
- Possible (rare) shard index corruption / different doc count on recovery (gateway / shard) (#466)
- constant_score query might apply deletes wrongly (#477)
- document level analyzer (analyzer, index_analyzer, search_analyzer) are not serialized (and not maintained across restarts) (#484)
- Parsing a deeply nested json might fail (#494)
- Histogram Facet: keys are wrongly ordered (#521)
- Query: match_all query (also in query_string: :) is very slow (#451)
- Thrift: Response might get corrupted with extra data (#452)
- (?) fix expected setting, had an additional
_ by mistake (commit)
