Re: Apache Ignite with Caching : How do I sure that cache(s) has all datas?

If you want to make sure all your data had been copied into backup nodes then you need to change synchronization mode to FULL_SYNC [1] Thanks, Amir [1] https://apacheignite.readme.io/docs/primary-and-backup-copies#section-synchronous-and-asynchronous-backups On Sat, Jul 7, 2018 at 8:14 AM monste

Re: Apache Ignite with Caching : How do I sure that cache(s) has all datas?

Rebalancing is a process when a node joins or leaves (in case backup is turned on) a cluster, data will be rebalanced within a cluster to make a fair distribution. It's applicable only for partitioned caches. But you have replicated cache and it's out of your case. Thanks, Amir On Jul 8, 2018 4:0

Hi Mikael, 1. This is just a warning informing you that Ignite's object serialization will differ from yours Externalizable implementation. By default Ignite will serialize all fields in object and if you want to customize then you need implement Binarylizable interface or set custom serializer as

You need to register a bean as follow Please check the link a sent you earlier it has tests with all required configurations. It can serve as a good example.

Re: Get all data of one cache in Ignite without creating a new ignite node

Hi Rick, In Ignite cache name is used as a database schema and a cache value type as a table name. So, in your case you should execute select * from "igniteCache".STRING to get your cache data. I would recomend you to run your Ignite instance with -DIGNITE_H2_DEBUG_CONSOLE=true parameter so you c

Hi, I think the answer to your question is no rather than yes. @QuerySqlField has a field target type and a field in interface is public, static and final. Thanks, Amir
