Overview

License : CPS-1026 Hazelcast Licensing


Hazelcast has two types of distributed objects in terms of their partitioning strategies:

  1. Data structures where each partition stores a part of the instance, namely partitioned data structures.

  2. Data structures where a single partition stores the whole instance, namely non-partitioned data structures.
