Hi, i'm seeing this on my aapanel. however i check my database, couldn't find any table which is unindexed. Also i've an another query. Yesterday i upgraded MYSQL 5.7 to MYSQL 8.0, before the update the average load & cpu usage was less than 10%. After the update it is more than 75-80%. My VPS has 8 cores CPU & 32GB of ram. Please help me out ASAP.
This is my mysql configuration.
