![]() ![]() Value = observable.timeout(100, TimeUnit.MILLISECONDS).toBlocking(). Rx.Observable observable = reactiveCommand.get(key) RedisReactiveCommands reactiveCommand = nnect().reactive() Lettuce can be optimized by taking the recommendation from the Cloudflare teams excellent analysis, which is 1. More specifically we should look at Lettuce which is the Redis client being used by Spring Data Redis. RedisClient client = RedisClient.create(uri) The next thing we think of is to enhance the client code which is written in Java. RedisURI uri = RedisURI.create("localhost", 6379) You will need the following entry in pom.xml file. This way, the application for only wait for that time for the response to come back, otherwise it will proceed by throwing a timeout exception. The Redis client library in Java, Lettuce, provides a way for the application to set a timeout on the query. Specifying multiple seed nodes helps to improve resiliency as Lettuce is able to connect the cluster even if a seed node is not available. The full cluster topology view (partitions) is obtained on the first connection so you’re not required to specify all cluster nodes. Normally redis is very fast, and can serve data in a few microseconds(1 microsecond is a thousandth of a millisecond), but it is possible that the network between the redis and the application is slow and it is leading to slow queries. Connecting to a Redis Cluster requires one or more initial seed nodes. In the above scenarios, to make sure that the requests are served as fast as possible, while having a backup plan(how to get the required data in case the timeout happens from redis), it is a good idea to set the timeout. This is particularly important in scenarios like getting the user profiles while writing adservers where the overall response time is expected to be less than 100 ms, and if any component takes more than a few milliseconds, it should be discarded and the flow should continue without it. ![]() the typical none default in several clients). Lettuce Redis library strong consistency using ReadFrom. How to use client consistent hashing with Lettuce Redis client. One of the points being suggested is regarding the socket timeout: Ensure that the socket timeout of the client is set to at least one second (vs. Im using lettuce client version 6.2.0 to connect to a Redis cluster (v 6.2) with 3 masters each having 1 replica. The Lettuce client is a Java-based library and it supports advanced features like. I am trying to follow this guide to increase my services resiliency. Yes, the Redis Lettuce client can connect to an Amazon ElastiCache cluster. While writing applications, sometimes we need to get the data within a particular time, and if the time taken by the redis or the networks is more than a particular time, the application may not want to wait that long for the data to come back and may take some other route. My application uses Lettuce Redis client to connect to AWS Elasticache. ![]()
