Description

Is your feature request related to a problem? Please describe.
Changing any part of the data prepper pipeline configuration requires restarting the entire data prepper node / cluster. This creates downtime for the service.

Describe the solution you'd like
Data Prepper does not require reloading for updates to processors, sink configurations or to add a new node to a cluster.

Describe alternatives you've considered (Optional)

  • A separate endpoint to update configurations

Additional context
I am open to alternatives and other ideas to make the management of data prepper pipelines easier.

Research direction

The issue names no files, tests, or entry points. Start by locating pipeline configuration loading and lifecycle management in the Java codebase, then clarify the reload mechanism and its scope with maintainers. Done would mean pipeline configuration changes, including processors, sinks, or new nodes, can be applied without restarting the Data Prepper service.
