// 'acquireTimeoutMillis' is the number of milliseconds before a timeout occurs when acquiring a
// connection from the pool. This is slightly different from connectionTimeout, because acquiring
// a pool connection does not always involve making a new connection, and may include multiple retries.
// when making a connection
config.pool.acquireTimeoutMillis = 60000; // 60 seconds
// 'createTimeoutMillis` is the maximum number of milliseconds to wait trying to establish an
// initial connection before retrying.
// After acquireTimeoutMillis has passed, a timeout exception will be thrown.
config.pool.createTimeoutMillis = 30000; // 30 seconds
// 'idleTimeoutMillis' is the number of milliseconds a connection must sit idle in the pool
// and not be checked out before it is automatically closed.
config.pool.idleTimeoutMillis = 600000; // 10 minutes
