Introduction

IEP has a SaveStream operator which can be used to store a stream of events to a database table. SaveStream is initially supported only on StreamInput. So a StreamInput can be connected to SaveStream operator to save it to a database table. Save and Replay Stream are explained in detail here

Now we have enabled SaveStream to be able to save data from any operator whose output is a stream. For example SaveStream now can be added to StreamProjectionAndFilter, InsertStream etc.

Following is the admin command to dynamically add SaveStream operator to any operator whose output is a stream:

addss ,addSaveStream {plan_name operator_name jndi_name tableName isGlobal<Optional>}: Add a save stream to an input stream operator.

rss ,removeSaveStream {plan_name save_operator_name}: Removes the save stream operator.
