[snaury]

Changelog entry

Fix uncommitted changes leak and clean them up on startup.

Changelog category

• Bugfix

Additional information

It was discovered that uncommitted changes are slowly leaking in some workloads, which turned out to be due to writes combined with a broken read-only lock. This patch fixes the issue and adds automatic cleanup on shard startup.

Fixes #13387.
