Version 3.2.0 by WSO2Category: Siddhi Function Support :
An event table can be backed with an RDBMS event store using the From annotation. This annotation also assigns the data source or the connection instructions to the event table. The RDBMS table name can be different to the event table name defined in Siddhi, and Siddhi always refers to the defined event table name. However the defined event table name cannot be same as an already existing stream name because the Siddhi Query Language considers both to be the same syntactically.
