Context¶
The large query isolation feature allows you to separately manage large queries. You can isolate query requests that consume a large amount of memory or take a long period of time. If the heap memory usage of a node is too high, the interrupt control program will be triggered. The program will interrupt a large query based on the policies you configured and cancel the running query tasks of the query.
You can also configure a global query timeout duration. Long queries will be intercepted.
Note
Currently, only versions 7.6.2 and 7.10.2 support large query isolation.
