   Configuration information for the connection pool.

   Configuration information for the connection pool.

   url

   The JDBC connection string.

   poolSize

   The size of the pool.

   connectionTimeout

   Maximum number of milliseconds that a client will wait for a connection from the pool. If this time is exceeded without a connection becoming available, a SQLException will be thrown from javax.sql.DataSource.getConnection().

   idleTimeout

   This property controls the maximum amount of time (in milliseconds) that a connection is allowed to sit idle in the pool. Whether a connection is retired as idle or not is subject to a maximum variation of +30 seconds, and average variation of +15 seconds. A connection will never be retired as idle before this timeout. A value of 0 means that idle connections are never removed from the pool.

   initializationFailTimeout

   the number of milliseconds before the pool initialization fails, or 0 to validate connection setup but continue with pool start, or less than zero to skip all initialization checks and start the pool without delay.

   maxLifetime

   This property controls the maximum lifetime of a connection in the pool. When a connection reaches this timeout, even if recently used, it will be retired from the pool. An in-use connection will never be retired, only when it is idle will it be removed. Should be bigger then 30000

   minimumIdle

   The property controls the minimum number of idle connections that HikariCP tries to maintain in the pool, including both idle and in-use connections. If the idle connections dip below this value, HikariCP will make a best effort to restore them quickly and efficiently.

   connectionInitSql

   the SQL to execute on new connections Set the SQL string that will be executed on all new connections when they are created, before they are added to the pool. If this query fails, it will be treated as a failed connection attempt.
