The table contains information about in-progress [data part moves](/docs/en/sql-reference/statements/alter/partition#move-partitionpart) of [MergeTree](/docs/en/engines/table-engines/mergetree-family/mergetree.md) tables. Each data part movement is represented by a single row.

-`elapsed` ([Float64](../../sql-reference/data-types/float.md)) — Time elapsed (in seconds) since data part movement started.
-`target_disk_name` ([String](disks.md)) — Name of [disk](/docs/en/operations/system-tables/disks/) to which the data part is moving.
-`target_disk_path` ([String](disks.md)) — Path to the mount point of the [disk](/docs/en/operations/system-tables/disks/) in the file system.
-`part_name` ([String](/docs/en/sql-reference/data-types/string.md)) — Name of the data part being moved.
-`part_size` ([UInt64](../../sql-reference/data-types/int-uint.md)) — Data part size.
