Columns:
- `event_date` ([Date](../../sql-reference/data-types/date.md)) — The date when the event happened.
- `event_time` ([DateTime64](../../sql-reference/data-types/datetime64.md)) — The date and time when the event happened.
- `event_time` ([DateTime](../../sql-reference/data-types/datetime.md)) — The date and time when the event happened.
- `event_time_microseconds` ([DateTime64](../../sql-reference/data-types/datetime64.md)) — The date and time with microseconds precision when the event happened.
- `id` ([UInt64](../../sql-reference/data-types/int-uint.md)) — ID of processor
- `parent_ids` ([Array(UInt64)](../../sql-reference/data-types/array.md)) — Parent processors IDs
- `plan_step` ([UInt64](../../sql-reference/data-types/int-uint.md)) — ID of the query plan step which created this processor. The value is zero if the processor was not added from any step.
- `plan_group` ([UInt64](../../sql-reference/data-types/int-uint.md)) — Group of the processor if it was created by query plan step. A group is a logical partitioning of processors added from the same query plan step. Group is used only for beautifying the result of EXPLAIN PIPELINE result.
- `initial_query_id` ([String](../../sql-reference/data-types/string.md)) — ID of the initial query (for distributed query execution).
- `query_id` ([String](../../sql-reference/data-types/string.md)) — ID of the query
- `name` ([LowCardinality(String)](../../sql-reference/data-types/lowcardinality.md)) — Name of the processor.
- `elapsed_us` ([UInt64](../../sql-reference/data-types/int-uint.md)) — Number of microseconds this processor was executed.
- `input_wait_elapsed_us` ([UInt64](../../sql-reference/data-types/int-uint.md)) — Number of microseconds this processor was waiting for data (from other processor).
- `output_wait_elapsed_us` ([UInt64](../../sql-reference/data-types/int-uint.md)) — Number of microseconds this processor was waiting because output port was full.
- `plan_step` ([UInt64](../../sql-reference/data-types/int-uint.md)) — ID of the query plan step which created this processor. The value is zero if the processor was not added from any step.
- `plan_group` ([UInt64](../../sql-reference/data-types/int-uint.md)) — Group of the processor if it was created by query plan step. A group is a logical partitioning of processors added from the same query plan step. Group is used only for beautifying the result of EXPLAIN PIPELINE result.
- `input_rows` ([UInt64](../../sql-reference/data-types/int-uint.md)) — The number of rows consumed by processor.
- `input_bytes` ([UInt64](../../sql-reference/data-types/int-uint.md)) — The number of bytes consumed by processor.
- `output_rows` ([UInt64](../../sql-reference/data-types/int-uint.md)) — The number of rows generated by processor.
