A page memory configuration for an Apache Ignite node. The page memory is a manageable off-heap based memory architecture that divides all continuously allocated memory regions into pages of fixed size. An individual page can store one or many cache key-value entries that allows reusing the memory in the most efficient way and avoid memory fragmentation issues. More...

By default, the page memory allocates a single continuous memory region. All the caches that will be configured in an application will be mapped to this memory region by default, thus, all the cache data will reside in that memory region.
If initial size of the default memory region doesn't satisfy requirements or it's required to have multiple memory regions with different properties then MemoryPolicyConfiguration can be used for both scenarios. For instance, using memory policies you can define memory regions of different maximum size, eviction policies, swapping options, etc. Once you define a new memory region you can bind particular Ignite caches to it.
To learn more about memory policies refer to MemoryPolicyConfiguration documentation.
