Partitiond Near Cache size and Offheap Eviction policy

asked by anil halil

Hi,

As i understant from docs near cache size is only meaningfull when we have partitioned cache. But i dont understant layering when i have partitioned cache with memory mode ONHEAP_TIERED. Does it have nearcache->localheap->offheap data layering in this case?

Actually, the answer is No, it has on-heap partitioned -> off-heap partitioned. The near cache is mostly a client-side cache with most recently accessed data. It is generally not very big and can be always kept on-heap.

You can think about Near cache as a client-side caching layer which sits in front of the partitioned cache.

Hope this makes sense.
