We are using an AWS RDS managed MySQL db.m4.2xlarge instance with db engine 5.7.30, we upgraded from 5.6 two days ago and have high CPU since - generally 10-15% higher reaching 100% at peek. Please can you help us understand the reason for this? N.B. noticeable drop in load over weekend expected.
The highest SQL load by waits are admin queries so this does not seem to be down to a badly optimised SQL:
We are using mysql-connector-java 8.0.21 to connect to the database and heavily use connection pooling, could this be a reason for this high usage selecting transaction isolation? N.B. this usage was high, but not as high, before the upgrade.
