Hi everyone,
I'm facing a issue with heap size
don't know how to increase it
tried changing the env var in the kube config (using Kubernetes for deployment )
but it struck at applying changes phase
thanks in advance
`circuitBreakingException[[parent] Data too large, data for [internal:index/shard/recovery/prepare_translog] would be [2080236780/1.9gb], which is larger than the limit of [2040109465/1.8gb], real usage: [2080236600/1.9gb], new bytes reserved: [180/180b], usages [request=101392/99kb, fielddata=2205790/2.1mb, in_flight_requests=180/180b, model_inference=0/0b, eql_sequence=0/0b, accounting=44755278/42.6mb]]`
