jedis/lettuce timeout

Lettuce

When we use Lettuce, we don’t need to configure the RedisConnectionFactory. Spring Boot does it for us.

All we have left, then, is to specify a few properties in our application.properties file:

spring.redis.database=0
spring.redis.host=localhost
spring.redis.port=16379
spring.redis.password=mypass
# timeout establishes the connection timeout
spring.redis.timeout=60000

Parameter	Description	Default value	Recommended settings
maxTotal	The maximum number of connections that are supported by the pool.	8	For more information, see Recommended settings.
maxIdle	The maximum number of idle connections in the pool.	8	For more information, see Recommended settings.
minIdle	The minimum number of idle connections in the pool.	0	For more information, see Recommended settings.
blockWhenExhausted	Specifies whether the client must wait when the resource pool is exhausted. Only when this parameter is set to true, the maxWaitMillis parameter takes effect.	true	We recommend that you use the default value.
maxWaitMillis	The maximum number of milliseconds that the client must wait when no connection is available.	A value of -1 specifies that the connection never times out.	We recommend that you do not use the default value.
testOnBorrow	Specifies whether to validate connections by using the PING command before the connections are borrowed from the pool.	Invalid connections are removed from the pool.	false
testOnReturn	Specifies whether to validate connections by using the PING command before the connections are returned to the pool.	Invalid connections are removed from the pool.	false
jmxEnabled	Specifies whether to enable Java Management Extensions (JMX) monitoring.	true	We recommend that you enable JMX monitoring. Take note that you must also enable the feature for your application.
