Contains information about currently running background fetches.

Columns:

- `database` ([String](../../sql-reference/data-types/string.md)) — Name of the database.

- `table` ([String](../../sql-reference/data-types/string.md)) — Name of the table.

- `elapsed` ([Float64](../../sql-reference/data-types/float.md)) — The time elapsed (in seconds) since showing currently running background fetches started.

- `progress` ([Float64](../../sql-reference/data-types/float.md)) — The percentage of completed work from 0 to 1.

- `result_part_name` ([String](../../sql-reference/data-types/string.md)) — The name of the part that will be formed as the result of showing currently running background fetches.

- `result_part_path` ([String](../../sql-reference/data-types/string.md)) — Absolute path to the part that will be formed as the result of showing currently running background fetches.

- `partition_id` ([String](../../sql-reference/data-types/string.md)) — ID of the partition.

- `total_size_bytes_compressed` ([UInt64](../../sql-reference/data-types/int-uint.md)) — The total size (in bytes) of the compressed data in the result part.

- `bytes_read_compressed` ([UInt64](../../sql-reference/data-types/int-uint.md)) — The number of compressed bytes read from the result part.

- `source_replica_path` ([String](../../sql-reference/data-types/string.md)) — Absolute path to the source replica.

- `source_replica_hostname` ([String](../../sql-reference/data-types/string.md)) — Hostname of the source replica.
