How to delete memory cache automatically once I have Out of Memory Error with Field Data breaker?

Elastic Stack Elasticsearch
1

Hello,

I am using Field data circuit breaker in order to define cache size for queries that we do during the day. And each night I am launching a script that deletes the memory cache but sometimes I have out of memory error during the day since they have been lots of queries launched so I need to clear the cache myself.

My question is, do we have any option for elasticsearch that cares about the cache clearing once out of memory error is received ?

Thank you

No, you need to do this manually at the moment.

Just like an electrical circuit breaker, if it is constantly tripping, this
indicates an overload condition.

Rather than try to empty out the fielddata memory, perhaps you should use
doc_values for the fields which are in the queries that are tripping the
circuit breaker.
