Use-Cases for Cassandra-Esper

Cassandra-Eser was built to provide access to a distributed key-value store for the Esper complex event processing engine. We assume that you have static data that you want to access from Esper.

When is Cassandra-Esper the right choice?

• you need to setup Esper in a distributed environment.
• your background data does not fit into main memory.
• your do not want to reload data when the background data changed.

When is Cassandra-Esper not the right choice?

• your static data fits easily into main memory.
• your static data is stored in a relational database management system (in that case you should use Esper's built-in support for SQL)
