Hi Shawn, > how to disable off heap completely? You cannot disable off-heap. As of 2.0, Apache Ignite stores all the data outside of java heap.
> does it mean half in on-heap and half in off-heap? On-heap caching allows to get a subset of the data into java heap and can be useful for scenarios when you do a lot of cache reads on server nodes that work with cache entries in the binary form or invoke cache entry deserialization.
