“[circuit_breaking_exception] [parent]” Data too large, data for “[]” would be error

After some more research finally, I found a solution for this i.e

  1. We should not disable circuit breaker as it might result in OOM error and eventually might crash elasticsearch.
  2. dynamically increasing circuit breaker memory percentage is good but it is also a temporary solution because at the end after solution increased percentage might also fill up.
  3. Finally, we have a third option i.e increase overall JVM heap size which is 1GB by default but as recommended it should be around 30-32 GB on production, also it should be less than 50% of available total memory.

For more info check this for good JVM memory configurations of elasticsearch on production, Heap: Sizing and Swapping
