I have installed HazelCast 2.5. I want to persist my records into disk. I learned that MapStore does this job. However i'm not sure how to implement MapStore.

Code I've written so far:

public class MyMaps implements MapStore {

public static Map mapCustomers = Hazelcast.getMap("customers");

public static void main(String[] args) {

{

mapCustomers.put(1, "Ram");

mapCustomers.put(2, "David");

mapCustomers.put(3, "Arun");

}

}

}

How do i put all these entries into disk.

Is it necessary to have a back-end like MySQL or PostgreSQL to use this class?

I believe the following function can be used:

public void delete(String arg0);

public void deleteAll(String arg0);

public void store(String arg0);

public void storeAll(String arg0);

I need a sample snippet of how to implement MapStore.

Please provide me with sample code.

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.
