Hi, 1. see: https://apacheignite.readme.io/docs/memory-configuration and: https://apacheignite.readme.io/docs/cache-configuration In some use cases dividing memory region is warranted: https://apacheignite.readme.io/docs/memory-architecture#memory-segment https://apacheignite.readme.io/docs/durable-memory-tuning#share-ram
2. This looks like a network error. Your client disconnected. see: https://apacheignite.readme.io/docs/thin-clients example: https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/client/ClientPutGetExample.java Thanks, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
