IGNITE-28651 Document Calcite SQL memory quotas in Ignite 2.x documentation#13113
Merged
Conversation
| The Calcite-based SQL engine can track and limit heap memory accounted by Calcite query execution operators. | ||
| This is useful for protecting a server node from a single large query or from many concurrent memory-heavy queries. | ||
|
|
||
| Two quotas can be configured in `CalciteQueryEngineConfiguration`: |
|
|
||
| Both quotas are disabled by default (`0`). | ||
| The quota values are specified in bytes. | ||
| If a quota is exceeded, the query fails with an `IgniteSQLException`. |
