Jerome Blanchard created UNOMI-924:
--------------------------------------
Summary: Impossible to call healthcheck concurrently
Key: UNOMI-924
URL: https://issues.apache.org/jira/browse/UNOMI-924
Project: Apache Unomi
Issue Type: Bug
Reporter: Jerome Blanchard
To avoid heavy load for healthcheck, a lock has been placed to raise an
exception when a healthcheck is already running.
This strategy seems good at the beginning but in production we are facing
concurrent calls to healthcheck from multiple HA Proxy nodes. As the lock
generated an HTTP error 500, HAProxy mark the unomi node as failing.
The goal is to fix that behavior by allowing concurrent calls but having only
one thread calculating healthcheck and a caching strategy.
