This patch fixes a bug where the memory monitor wouldn't reclaim the memory allocated to events corresponding to unwatched column families for a changefeed that targets only a subset of a table's families. Release note (bug fix): A bug where a changefeed targeting only a subset of a table's column families could become stuck has been fixed.

Thanks for opening a backport. Before merging, please confirm that the change does not break backwards compatibility and otherwise complies with the backport policy. Include a brief release justification in the PR description explaining why the backport is appropriate. All backports must be reviewed by the TL for the owning area. While the stricter LTS policy does not yet apply, please exercise judgment and consider gating non-critical changes behind a disabled-by-default feature flag when appropriate. |
