A lightweight predecessor to the Extended Decoupler session agent, the Decoupler session agent uses an in-memory queue for queuing up hits for processing and does not queue any hits to disk. If the in-memory queue is filled, hits are dropped. Extended Decoupler session agent is configured to always queue sessions to disk if the in-memory queue is filled.

The configuration settings for Decoupler session agent is a subset of those in Extended Decoupler session agent. You can add the session agent through the Pipeline Editor and adjust the size of the in-memory queue (Max Queue Size).
