Infinispan 14 indexing & query news

Hibernate annotations are going to be replaced with the new Infinispan indexing annotations, that will be used in the same exact way for both embedded and remote queries.

Here is an example of two annotated POJOs:

Indexed fields without any special string/text transformation will be annotated as @Basic. If we need to apply a normalizer to a String field, we will opt for a @Keyword annotation. If we need to apply an analyzer to a String field, we will opt for a @Text annotation.

The new annotations allow setting with the same annotation if the field should be sortable, or projectable, or its normalizer or its analyzer. However, not all the combinations will be possible, for instance the attribute sortable is not present on the @Text annotation, since an analyzed field cannot be used to sort the result set.

indexNullAs attribute allow now to define a default value to use on index in case the corresponding entity values was null.

Embedded indexes are defined using the @Embedded annotation, and it is possible to choose between the NESTED structure which preserves the original object relationship structure and FLATTENED structure which makes the leaf fields multi-valued fields of the parent entity.
