Understanding elasticsearch circuit_breaking_exception
Let us see what we have here, step by step:
[parent] Data too large, data for [<http_request>]gives the name of the circuit breaker
would be [1031753160/983.9mb], says, how the heap size will look, when the request would be executed
which is larger than the limit of [986932838/941.2mb],tells us the current setting of the circuit breaker above
real usage: [1002052432/955.6mb],this is the real usage of the heap
new bytes reserved: [29700728/28.3mb],actually an estimatiom, what impact the request will have (the size of the data structures which needs to be created in order to process the request). Your ~10MB file will probably consume 28.3MB.
usages [ request=0/0b, fielddata=0/0b, in_flight_requests=29700728/28.3mb, accounting=202042/197.3kb]This last line tells us how the estmation is being calculated.
