Contains information about maximums for all intervals of all quotas. Any number of rows or zero can correspond to one quota.
Columns:
- `quota_name` ([String](../../sql-reference/data-types/string.md)) — Quota name.
- `duration` ([UInt32](../../sql-reference/data-types/int-uint.md)) — Length of the time interval for calculating resource consumption, in seconds.
- `is_randomized_interval` ([UInt8](../../sql-reference/data-types/int-uint.md#uint-ranges)) — Logical value. It shows whether the interval is randomized. Interval always starts at the same time if it is not randomized. For example, an interval of 1 minute always starts at an integer number of minutes (i.e. it can start at 11:20:00, but it never starts at 11:20:01), an interval of one day always starts at midnight UTC. If interval is randomized, the very first interval starts at random time, and subsequent intervals starts one by one. Values:
- `0` — Interval is not randomized.
- `1` — Interval is randomized.
- `max_queries` ([Nullable](../../sql-reference/data-types/nullable.md)([UInt64](../../sql-reference/data-types/int-uint.md))) — Maximum number of queries.
- `max_query_selects` ([Nullable](../../sql-reference/data-types/nullable.md)([UInt64](../../sql-reference/data-types/int-uint.md))) — Maximum number of select queries.
- `max_query_inserts` ([Nullable](../../sql-reference/data-types/nullable.md)([UInt64](../../sql-reference/data-types/int-uint.md))) — Maximum number of insert queries.
- `max_errors` ([Nullable](../../sql-reference/data-types/nullable.md)([UInt64](../../sql-reference/data-types/int-uint.md))) — Maximum number of errors.
- `max_result_rows` ([Nullable](../../sql-reference/data-types/nullable.md)([UInt64](../../sql-reference/data-types/int-uint.md))) — Maximum number of result rows.
- `max_result_bytes` ([Nullable](../../sql-reference/data-types/nullable.md)([UInt64](../../sql-reference/data-types/int-uint.md))) — Maximum number of RAM volume in bytes used to store a queries result.
- `max_read_rows` ([Nullable](../../sql-reference/data-types/nullable.md)([UInt64](../../sql-reference/data-types/int-uint.md))) — Maximum number of rows read from all tables and table functions participated in queries.
- `max_read_bytes` ([Nullable](../../sql-reference/data-types/nullable.md)([UInt64](../../sql-reference/data-types/int-uint.md))) — Maximum number of bytes read from all tables and table functions participated in queries.
- `max_execution_time` ([Nullable](../../sql-reference/data-types/nullable.md)([Float64](../../sql-reference/data-types/float.md))) — Maximum of the query execution time, in seconds.
