Improved Keeper performance by moving changelog files between disks in a background thread instead of blocking the entire service during the operation.
Why it matters
Previously, moving Keeper changelog files to a different disk would block the entire Keeper service until the move completed, causing performance degradation especially during long operations like moving to an S3 disk. This improvement allows these moves to happen asynchronously, reducing service interruptions and improving overall stability and responsiveness.How to use it
No special user action is required. The movement of changelog files between disks by Keeper is now handled automatically in a background thread, transparently improving performance during disk changes.
