Hi, First, ignite will take all space that is configured in a data region. if there's more data then data region can store it will write data to a disk. However, it's about off-heap memory only, it doesn't use the heap for data storing(at least by default). How to configure data region size you can read here: https://apacheignite.readme.io/docs/memory-configuration
So you need to sum jvm heap size, off-heap size and memory for OS and tools and this sum must be < total memory your box has. Thanks, Mike. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
