-   `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.

-   `source_replica_port` ([UInt16](../../sql-reference/data-types/int-uint.md)) — Port number of the source replica.

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

-   `URI` ([String](../../sql-reference/data-types/string.md)) — Uniform resource identifier.

-   `to_detached` ([UInt8](../../sql-reference/data-types/int-uint.md)) — The flag indicates whether the currently running background fetch is being performed using the `TO DETACHED` expression.

-   `thread_id` ([UInt64](../../sql-reference/data-types/int-uint.md)) — Thread identifier.
