# system.quota_limits

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) — Quota name.
- `duration` (UInt32) — Length of the time interval for calculating resource consumption, in seconds.
- `is_randomized_interval` (UInt8) — 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(UInt64)) — Maximum number of queries.
- `max_query_selects` (Nullable(UInt64)) — Maximum number of select queries.
- `max_query_inserts` (Nullable(UInt64)) — Maximum number of insert queries.
- `max_errors` (Nullable(UInt64)) — Maximum number of errors.
- `max_result_rows` (Nullable(UInt64)) — Maximum number of result rows.
- `max_result_bytes` (Nullable(UInt64)) — Maximum number of RAM volume in bytes used to store a queries result.
- `max_read_rows` (Nullable(UInt64)) — Maximum number of rows read from all tables and table functions participated in queries.
- `max_read_bytes` (Nullable(UInt64)) — Maximum number of bytes read from all tables and table functions participated in queries.
- `max_execution_time` (Nullable(Float64)) — Maximum of the query execution time, in seconds.
