Hi team, another question: does Druid automatically drop a connection after it has been idle for some time (like 10 min)? Basically, we are using Hikari connection pool from a spring-boot based microservice API to connect to druid router, and maintains a size=15 connection pool at all times. We observe that after idling for about 10 min, the API cannot connect to Druid (the error is: AvaticaClientRunTimeException: Remote driver error null; Error 1 (00000) ERROR. Thanks in advance!
