Hi team, Druid Mysql memory consumption is exponentially increasing till 15.5 GB. Do you think, having the long connections cause this high memory utilization ? I checked the data present in the tables is reasonable. please let me know, if you have any thoughts around this. ?? below is the mysql innodb server status output. FYI (mysql server version 5.7)
