Apache IGNITE 2.3

Putting aside the regular bug fixes and performance optimizations, the Apache Ignite 2.3 release brings new SQL capabilities and Ignite persistence improvements that are worth mentioning.

Ignite Persistence

Before Ignite version 2.3, the persistence could be enabled globally only. Now, it's up to you to decide which data to persist and which to store in RAM only. The persistence can be configured via data regions.
