Defaults to 2. The value must be smaller than auth\_cache\_ttl and ttl else Router won't start. * auth\_cache\_ttl | int Default: -1 Time (in seconds) until the cache becomes invalid if not refreshed. Defaults to -1 (infinite). The value must be larger than auth\_cache\_refresh\_interval else Router won't start. * base-port | int Default: 3306 Base port number for RW interface. RO, xRW and xRO will increment from base\_port. * debug | boolean Enable debug logging * max\_connections | int Default: 1024 If mysql router version < 8.0.27, this option will be set as max\_connections in the config. Else will be max\_total\_connections. The max\_connections is maximum number of connections to allow in direction to each MySQL routing sessions, with one for the RW unit and another one for the RO units of the MySQL innodb cluster. A valid range is between 1 and 65535. The max\_total\_connections is the maximum number of client connections handled by Router, to help prevent running out of the file descriptors. A valid range is between 1 and 9223372036854775807. * source | string Default: distro Repository from which to install. May be one of the following: distro (default), ppa:somecustom/ppa, a deb url sources entry, or a supported Ubuntu Cloud Archive e.g. . cloud:- cloud:-/updates cloud:-/staging cloud:-/proposed . See https://wiki.ubuntu.com/OpenStack/CloudArchive for info on which cloud archives are available and supported. * ssl\_ca | string TLS CA to use to communicate with other components in a deployment. . \_\_NOTE\_\_: This configuration option will take precedence over any certificates received over the ``certificates`` relation. * ssl\_cert | string TLS certificate to install and use for any listening services. . \_\_NOTE\_\_: This configuration option will take precedence over any certificates received over the ``certificates`` relation. * ssl\_key | string TLS key to use with certificate specified as ``ssl\_cert``. . \_\_NOTE\_\_: This configuration option will take precedence over any certificates received over the ``certificates`` relation. * ttl | float Default: 0.5 Time to live (in seconds) of information in the metadata cache. Accepts either an integer or a floating point value. The granularity is limited to milliseconds, where 0.001 equates to one millisecond. Precision is truncated to the supported range; for example ttl=0.0119 is treated as 11 milliseconds. The value 0 means that the metadata cache module queries the metadata continuously in a tight loop. * use-syslog | boolean Setting this to True will allow supporting services to log to syslog. * use\_gr\_notifications | boolean Enables Group Replication notifications. When enabled, the mysql router is asynchronously notified about most cluster changes. This allows for a higher ttl value, as periodic metadata refreshes serve as an additional safeguard rather than the primary method of keeping cluster state information up to date. When disabled, a low ttl value (such as 0.5s, the default) is recommended to reduce the cache misalignment window between routers and mysql clusters.
