The reason for that has a rather long story, but I will try to shorten it as much as possible. There is one application that uses Elasticsearch for performing different search operations. I will call it “Search App” below in text. Current application was migrated...

Here is the screen for AWS CloudWatch how it looked. While analyzing release by itself, I found a lot of changes related with...
