Compact data of each TiKV manually

Use the compact command to manually compact data of each TiKV.

• Use the --from and --to options to sepecify the compact range in the form of escaped raw key. If not set, the whole range will be compacted.

• Use the --region option to compact range of a specific region. If set, --from and --to will be ignored.

• Use the --db option to specify the RocksDB that performs compaction. The optional values are kv and raft.

• Use the --threads option allows you to specify the concurrency for the TiKV compaction and its default value is 8. Generally, a higher concurrency comes with a faster compaction speed, which might yet affect the service. You need to choose an appropriate concurrency count based on your scenario.

• Use the --bottommost option to include or exclude the bottommost files when TiKV performs compaction. The value options are default, skip, and force. The default value is default.

  • default means that the bottommost files are included only when the Compaction Filter feature is enabled.
  • skip means that the bottommost files are excluded when TiKV performs compaction.
  • force means that the bottommost files are always included when TiKV performs compaction.

• For local mode
  {{< copyable "shell-regular" >}}

$ tikv-ctl --data-dir /path/to/tikv compact --db kv
success!

• For remote mode
  {{< copyable "shell-regular" >}}

$ tikv-ctl --host ip:port compact --db kv
success!
