> We recently evaluated JDBC connections pools for Java SE and were impressed by the connection validation algorithm implemented by [HikariCP|https://github.com/brettwooldridge/HikariCP]. We would like to see something similar implemented by Agroal.
> HikariCP implements validate-on-borrow using {{java.sql.Connection.isValid(int)}} (Java 1.6/JDBC 4.0). However if the connection has been successfully used in the past 500ms then this check is bypassed. To quote the author
> {quote}Generally speaking, in an active application or process, this avoids nearly all validation, while providing confidence that the connections returned by the pool are actually alive.{quote}
> Discussion is here https://groups.google.com/forum/#!searchin/hikari-cp/batch%7Csort:date/hikari-cp/6XOI8_x9YeU/G3k6g9otAAAJ
