Design Description


Why Use Logical Caches

Logical caches help to minimize overhead brought by Apache Ignite internal data structures that support caches and internals:

  1. Less heap allocated for partition location maps.
  2. Shorter and faster partition map exchanges.
  3. Decreased number open files in case of data persistence.

API Changes

TBD: how to use logical caches

Possible Impacts

TBD: what user should be aware of when using Logical Caches.

Iteration speed?

Updates during rebalancing?

Concurrent updates?
