elasticsearch - FIELDDATA Data is too large

Question

I open kibana and do a search and i get the error where shards failed. I looked in the elasticsearch.log file and I saw this error:

org.elasticsearch.common.breaker.CircuitBreakingException: [FIELDDATA] Data too large, data for [@timestamp] would be larger than limit of [622775500/593.9mb]

Is there any way to increase that limit of 593.9mb?

Answer 1

You can try to increase the fielddata circuit breaker limit to 75% (default is 60%) in your elasticsearch.yml config file and restart your cluster:

indices.breaker.fielddata.limit: 75%

Or if you prefer to not restart your cluster you can change the setting dynamically using:

curl -XPUT localhost:9200/_cluster/settings -d '{
  "persistent" : {
    "indices.breaker.fielddata.limit" : "40%" 
  }
}'

Give it a try.
