I've created two containers running each one instance of Art, accessing exactly same database. On front of these containers, I've HaProxy making load balance between requests. The problem is, quite frequently, when one instance change some report metadata (ex: groups that a report belongs to), the other instance did not see this change until restart. Is there any parameter I can set to make ART do not cache (Spring config, Ehcache, etc?) any metadata data? Thanks in advance, ER.

That's insane, man :-) good to know, we may use in future perhaps! At this point, we're already on the process of merging data from PostgreSQL with CockroachDB.

Not yet, but I'm considering to. I think its would add some additional flexibility

Would you have evaluated using cqengine? https://github.com/npgall/cqengine

Uau!!! Thanks, Fred! This is really extensive and valuable information. I'll look at it in details right now. Regards, ER.

Hi! I've re-read all docs, but found not answer for my needs. I do have heterogeneous databases (PostgreSQL, CockroachDB, Cassandra DB) and I have to build a report querying all of them, and then consolidating result in one report. I've been burning my eyebrows, but found no way to do that. Do you have any tips? Thanks in advance, Edson Richter

Actually, I do believe this is more about the library (and eventual breaking changes) than Art itself. IMHO, it is impossible to anticipate the impact. I would recommend you to run a test setup with the new library and check impacts - don't forget to share the results, it would help to update Art libraries in new versions. Regards, Edson
