- elapsed(Float64) — Time elapsed (in seconds) since data part movement started.
- target_disk_name(String) — Name of disk to which the data part is moving.
- target_disk_path(String) — Path to the mount point of the disk in the file system.
- part_name(String) — Name of the data part being moved.
- part_size(UInt64) — Data part size.
- thread_id(UInt64) — Identifier of a thread performing the movement.
