Steps for using the MemoryStore
To use the MemoryStore, you must first add the MemoryStore bundle to your project, unless you are using the distributed MemoryStore. (If you are using the distributed MemoryStore, instead of adding the MemoryStore bundle, you need to add the Distributed MemoryStore adapter. For more information on this, see
Adding distributed MemoryStore support to a project.) After you add the MemoryStore bundle, you write EPL that does the following:
1. Prepare and then open a store that will contain one or more tables.
2. Define the data schema for the rows that will belong to the table.
3. Prepare and then open a table in a store.
4. For applications that will access data in a distributed store, if the underlying third-party distributed cache provider supports notifications, optionally subscribe to the table in order to receive notifications when data has changed. For see further information,
Notifications.
5. Get a new or existing row from the table.
6. Modify the row.
7. Commit the modified row to the table.
8. Repeat the three previous steps as often as needed.
9. Optionally, use an iterator to step through all rows in the table.
10. Optionally, store the in-memory table on disk.
