Channels (Web) Service response spike during release deployment
The Support Team here have noticed high spikes in response times whenever there is product jar deployment for a Business As usual change in production.
Also to add, these spikes are observed on all nodes which are configured to run the Web services.
Steps to Reproduce
Import rules which include a change in the Application rule which consists in referencing different ruleset version.
This issue was determined to be a product enhancement request FDBK-17676.
Here’s the explanation for the reported behavior:
As the Application rule is changed, the ruleset list is also changed.
The rule resolution cache is associated to a particular ruleset list.
So this has to be rebuilt hence a spike in response time for the time this cache gets rebuilt.
