Code I\'v

Answer 1

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

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

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

Partitioned Hazelcast data structures persistence data to local file system is not supported,need a centralized system that is accessible from all hazelcast members,like mysql or mongodb.

You can get code from hazelcast-code-samples.

Answer 2

Yes, you can use MapStore and MapLoader to persist file to local storage. Read official documentation here.
