Extensions for io.vertx.redis.sentinel.RedisSentinel

ckquorumAwait

suspend fun RedisSentinel.ckquorumAwait(name: String): String

Check if the current Sentinel configuration is able to reach the quorum needed to failover a master, and the majority needed to authorize the failover. This command should be used in monitoring systems to check if a Sentinel deployment is ok.

closeAwait

suspend fun RedisSentinel.closeAwait(): Unit

Close the client - when it is fully closed the handler will be called.

failoverAwait

suspend fun RedisSentinel.failoverAwait(name: String): String

Force a failover as if the master was not reachable, and without asking for agreement to other Sentinels (however a new version of the configuration will be published so that the other Sentinels will update their configurations)

flushConfigAwait

suspend fun RedisSentinel.flushConfigAwait(): Unit

Force Sentinel to rewrite its configuration on disk, including the current Sentinel state. Normally Sentinel rewrites the configuration every time something changes in its state (in the context of the subset of the state which is persisted on disk across restart). However sometimes it is possible that the configuration file is lost because of operation errors, disk failures, package upgrade scripts or configuration managers. In those cases a way to to force Sentinel to rewrite the configuration file is handy. This command works even if the previous configuration file is completely missing.

getMasterAddrByNameAwait

suspend fun RedisSentinel.getMasterAddrByNameAwait(name: String): JsonArray

Return the ip and port number of the master with that name. If a failover is in progress or terminated successfully for this master it returns the address and port of the promoted slave

masterAwait

suspend fun RedisSentinel.masterAwait(name: String): JsonArray

Show the state and info of the specified master

mastersAwait

suspend fun RedisSentinel.mastersAwait(): JsonArray

Show a list of monitored masters and their state

resetAwait

suspend fun RedisSentinel.resetAwait(pattern: String): Unit

Reset all the masters with matching name. The pattern argument is a glob-style pattern. The reset process clears any previous state in a master (including a failover in pro

sentinelsAwait

suspend fun RedisSentinel.sentinelsAwait(name: String): JsonArray

Show a list of sentinel instances for this master, and their state

slavesAwait

suspend fun RedisSentinel.slavesAwait(name: String): JsonArray

Show a list of slaves for this master, and their state
