      • HIKARI_MAX_LIFETIME

        static final String HIKARI_MAX_LIFETIME

        Constant Field Values

      • HIKARI_VALIDATION_TIMEOUT

        static final String HIKARI_VALIDATION_TIMEOUT
        The maximum amount of time that a connection will be tested for aliveness. Must be lower than HIKARI_ACQUISITION_TIMEOUT.

        The default is 5000 milliseconds (5 seconds).

        Constant Field Values

      • HIKARI_INITIALIZATION_TIMEOUT

        static final String HIKARI_INITIALIZATION_TIMEOUT
        The maximum amount of time the application thread can wait to attempt to acquire an initial connection. Applied after HIKARI_ACQUISITION_TIMEOUT.

        The default is 1 millisecond.

        See Also:
        Constant Field Values

      • HIKARI_KEEPALIVE_TIME

        static final String HIKARI_KEEPALIVE_TIME
        How often connections will attempt to be kept alive to prevent a timeout.

        The default is 0 milliseconds, resulting in no keep-alive behaviour.

        Constant Field Values

      • HIKARI_INITIAL_SQL

        static final String HIKARI_INITIAL_SQL
        An SQL command to be executed when a connection is created.

        static final String HIKARI_READ_ONLY
        If true, connections obtained from the pool are in read-only mode by default.

        Some databases do not support read-only mode while some will provide query optimizations when a connection is in read-only mode.

        The default is false.
