Upgrading from 4.0.x to 4.1.x
This section describes breaking changes from version 4.0.x to 4.1.x and how removed features can be replaced by new introduced features.
Deprecations
It is possible to define a property of en entity as the id property by naming it either id or document.
This behaviour is now deprecated and will produce a warning.
Please use the @Id annotation to mark a property as being the id property.
In the ReactiveElasticsearchClient.Indices interface the updateMapping methods are deprecated in favour of the putMapping methods.
They do the same, but putMapping is consistent with the naming in the Elasticsearch API:
In the IndexOperations interface the methods addAlias(AliasQuery), removeAlias(AliasQuery) and queryForAlias() have been deprecated.
The new methods alias(AliasAction), getAliases(String…) and getAliasesForIndex(String…) offer more functionality and a cleaner API.
Usage of a parent-id has been removed from Elasticsearch since version 6. We now deprecate the corresponding fields and methods.
Removals
The type mappings parameters of the @Document annotation and the IndexCoordinates object were removed.
They had been deprecated in Spring Data Elasticsearch 4.0 and their values weren’t used anymore.
Breaking Changes
Return types of ReactiveElasticsearchClient.Indices methods
The methods in the ReactiveElasticsearchClient.Indices were not used up to now.
With the introduction of the ReactiveIndexOperations it became necessary to change some of the return types:
-
the
createIndexvariants now return aMono<Boolean>instead of aMono<Void>to signal successful index creation. -
the
updateMappingvariants now return aMono<Boolean>instead of aMono<Void>to signal successful mappings storage.
