Volatile Storage

Overview

Ignite Volatile storage is designed to provide a quick and responsive storage without guarantees of data persistence.

When it is enabled for the data region, Ignite stores all data in the data region in RAM. Data will be lost on cluster shutdown, so make sure to have a separate data region for persistent storage.
