Yes it sounds like we agree about HSEARCH-2164 being a blocker. But will we regret this? what if we later decide that supporting multiple Elasticsearch clusters is both of low value and too problematic? Not sure if we're yet in a position to be aware of all implications; I guess I shouldn't worry too much as this is still experimental, yet I think it would be good to go through our list of features via the reference documentation and try thinking ahead of what problems that will introduce. I didn't find any point which wouldn't be easy to dismiss but a second pair of brains would be nice on this ;) Thanks, Sanne > > > --Gunnar > > 2016-03-08 12:55 GMT+01:00 Sanne Grinovero <sa...@hibernate.org>: >> Today our experiments are assuming we're connecting to a single >> Elasticsearch cluster: one hostname to configure, etc.. >> >> I think this is an acceptable limitation for version 5.6 (our first >> stable milestone to support this integration) but I'm wondering if we >> should document it as a temporary limitation or as an intentional >> design. >> >> I think that eventually we should allow having different entities >> (indexes) to be stored on different ES clusters; this shouldn't be too >> hard to manage as the codebase is already structured around this >> capability of having different types in different "indexes"; so while >> a single Elasticsearch cluster can manage multiple indexes (that's a >> bit of a novel concept) I see no reason to not allow different indexes >> to be mapped on different clusters. >> >> = Am I missing some strong reason to not allow this? >> >> = While this will (likely) not be supported in 5.6, should the public >> API and configuration properties allow for this to be configured >> per-index already?
