How to change indexing_pressure.memory.limit configuration

Elastic Stack Elasticsearch
1

My es version is 7.17.5, single node.
I notice that my fluent-bit return following error log:

{"log":"{\"error\":{\"root_cause\":[{\"type\":\"es_rejected_execution_exception\",\"reason\":\"rejected execution of coordinating operation [coordinating_and_primary_bytes=836343170, replica_bytes=0, all_bytes=836343170, coordinating_operation_bytes=6029, max_coordinating_and_primary_bytes=836344217]\"}],\"type\":\"es_rejected_execution_exception\",\"reason\":\"rejected execution of coordinating operation [coordinating_and_primary_bytes=836343170, replica_bytes=0, all_bytes=836343170, coordinating_operation_bytes=6029, max_coordinating_and_primary_bytes=836344217]\"},\"status\":<mark>429</mark>}

I check the document, I notice that is es JVM heap memory is not enough.
So I add a heap.options under /etc/elasticsearch/jvm.options.d

I'm just curious, how should I adjust indexing_pressure.memory.limit? Is it OK if I append

indexing_pressure.memory.limit: 15%

to /etc/elasticsearch/elasticsearch.yml ?
I can't find any example document under here and here

What is the output of the cluster stats API?

I don't know why you asking me the cluster stats? Is it relevant to how to configure ES?
