Pierre Villard created NIFI-4143:
------------------------------------
Summary: Make configurable maximum number of concurrent requests
Key: NIFI-4143
URL: https://issues.apache.org/jira/browse/NIFI-4143
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Reporter: Pierre Villard
At the moment, the maximum number of concurrent requests is hard coded in
{{ThreadPoolRequestReplicator}}
https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-framework-cluster/src/main/java/org/apache/nifi/cluster/coordination/http/replication/ThreadPoolRequestReplicator.java
The value is equal to 100.
In some situations where multiple factors are combined (large cluster, S2S to
load balance data in the cluster, multiple users accessing the UI), the limit
can be reached and the UI may become intermittently unavailable with the
message: "There are too many outstanding HTTP requests with a total 100
outstanding requests".
This value should be configurable in nifi.properties allowing users to increase
the value.
