The filterMany( <string expressions> ) uses the language parser which
ultimately will we probably remove in ebean 15.x
Code can migrate to filterManyRaw() instead or better yet change to
use the improved query beans filterMany( <closure> ) option that will
be included in this same ebean release.
Query beans also generate a "Assoc" query bean that is used
for the relationships. Previously these were generated into a
.query.assoc package and with this they are generated as an
inner class of the query bean.
This then allows the change where an additional filterMany()
is generated on the "Assoc" bean that takes a closure. This
simplifies the use of query beans for filterMany.
This change to the generated query beans needs a change to the
ebean-agent enhancement.
A parent in the Inheritance hierarchy has @DiscriminatorValue but not the @Inheritance annotation. The bug means the inherited properties are not included on the generated query bean.
The fix is to the querybean-generator to pick up inherited properties for this case.
This is a variation of findEach() that makes it easy to have a batch consumer processing a large result in batches. For example, process in batches of 50 beans.
Note that the last batch consumed/processed will often have less than the batch size.
