Re: Access a cache loaded by DataStreamer with SQL

I guess I am not understanding how to build this for multiple tables in a cache that can be loaded using the datastreamer and are queryable from DBeaver or tableau. I changed the code to be IgniteCache testCache = ignite.getOrCreateCache(new CacheConfiguration<>("MAIN")

Re: Ignite 2.7 Errors

Thank you, IIya! We ended up using cfg.setFailureHandler(new NoOpFailureHandler()); it silenced the errors and no more stack dumps, etc. and it seems to work like in 2.5 and 2.6, with no other changes. I am still curious if in the future I can take that line out if 2.7 is more stable or 2.8.

Re: How to disable replication over multicast for development nodes?

Hi. To disable multicast, you need to change "ipFinder" in "discoverySpi" configuration to "TcpDiscoveryVmIpFinder" and specify the list of node's addresses. Check the link below for the configuration example: https://apacheignite.readme.io/docs/tcpip-discovery#section-static-ip-finder Regards,

Re: How many Ignite nodes per Server + backup behavior

Hello, 1. It's recommended to run 1 Ignite node per server, try to reduce nodes count to 4. 2. In case you're going to use 4 nodes per server, you need to specify backup=1 and also set excludeNeighbors on affinityFunction as described here:

Re: InvalidClassException local class incompatible for custom cache store factory

Ken, Cache store factory is a part of a cache configuration. So, if a cache configuration is stored somewhere, and it's deserialized using a new class, then this exception is thrown. It's possible if you have native persistence enabled, for example. The cache configuration is read from disk when
