🎯API Stability
Long-TermThis API is stable and will remain supported across versions with minimal breaking changes.

Summary

The updateFdrFeedControl() mutation updates administrator controls for an FDR feed in a LogScale repository. Adjust polling node limits and per-node file download parallelism after the feed is created. To update the feed configuration itself (name, credentials, and so on), use updateFdrFeed() instead.

Syntax

graphql
updateFdrFeedControl(
      input: UpdateFdrFeedControl!
   ): FdrFeedControl!

The mutation accepts a single required input argument of type UpdateFdrFeedControl!. The input includes the repository name, FDR feed ID, and control settings to update. The mutation returns a non-null FdrFeedControl! object.

The returned FdrFeedControl! object reflects the updated control settings.

Input parameters

Provide the repository name, the FDR feed ID, and the control values to update. To find the feed ID, use the repository() query shown in the Related section.
