Semen Boikov commented on IGNITE-1232:
--------------------------------------
Progress update:
- added more tests
- fixed minor issues in GridH2CollocationModel with union parsing
- found out that if REPLICATED cache is in the middle of join (P -> R -> P)
then result may contain duplicates, to aovid this cost caclulcation in
GridH2CollocationModel was modified so that optimizer will always place
replicated caches at the end
- added checks that distributed join condition uses index and cache
partiticpated in join query does not have custom affinity mapper, otherwise
query throws an exception
- found issue in H2 code related to batch joins (reproduced by
IgniteCacheDistributedJoinQueryConditionsTest.testJoinQuery6), Sergi promised
to take a look
> Support distributed SQL JOIN
