Introduction to using the MemoryStore
Data that the MemoryStore stores must be one of the following types: boolean, float, integer or string.
To use the MemoryStore, you add the MemoryStore Plugin bundle to your Apama project. This lets you create instances of MemoryStore events and then call actions on those events. Available actions include the following:
Creating stores that contain tables
Defining the schema for the rows in a table
Creating tables and associating a schema with each table
Storing, retrieving, updating, and committing rows of data
Copying tables to disk to make the data persistent
Making stored data available in data views for use by dashboards
You can use the MemoryStore in parallel applications. You can use the MemoryStore in a persistent monitor in a persistence-enabled correlator. See
Using the MemoryStore when persistence is enabled.
For information on using the MemoryStore in a distributed fashion, see
Using the distributed MemoryStore.
