GenericObjectPool : borrowObject method when machine gets down - redis

Question

I am using below code to create a Redis connection pool
GenericObjectPool<StatefulRedisConnection> poolConnections = ConnectionPoolSupport.createGenericObjectPool(
() -> client.connect(), genericObjectPoolConfig);
System.out.println(new Date()+ "..gettign conn from pool..11")
StatefulRedisConnection connection = poolConnections.borrowObject();
It is working fine. However, in 1 use case when redis machine went down then it take borrowObject takes 10 sec to throw exception. I know it may be due to redis lettuce implementation.

Sun Jul 05 17:35:55 IST 2020Exception in pushInList() : io.lettuce.core.RedisConnectionException: Unable to connect to 10.32.17.242:11896
Any one suggest how to reduce this time. I want it to throw exception in less than 10 sec. Is there any configuration ?

This is most likely the cause of a socket timeout. In the Lettuce documentation here you can see the default connect timeout is 10 seconds.
You can customize this default socket timeout by updating your RedisClient. In the example below I changed the timeout to be one second.
SocketOptions socketOptions = SocketOptions.builder().connectTimeout(Duration.ofSeconds(1)).build();
ClientOptions clientOptions = ClientOptions.builder().socketOptions(socketOptions).build();
RedisClient redisClient = RedisClient.create(DefaultClientResources.builder().build());
redisClient.setOptions(clientOptions);
