Can I use ElastiCache as a database?

You can use ElastiCache for caching, which accelerates application and database performance, or as a primary data store for use cases that don't require durability like session stores, gaming leaderboards, streaming, and analytics.

Which Java client is supported by Redis?

In this tutorial, we'll introduce Jedis, a client library in Java for Redis. This popular in-memory data structure store can persist on a disk as well.

What is Redis client?

Redis has a client-server architecture and uses a request-response model. Applications send requests to the Redis server, which processes them and returns responses for each. The role of a Redis client library is to act as an intermediary between your application and the Redis server.

What is the use of Redis client?

The CLIENT Command

The Redis CLIENT command allows you to inspect the state of every connected client, to kill a specific client, and to name connections. It is a very powerful debugging tool if you use Redis at scale. In the above example two clients are connected to the Redis server.

What is Amazon ElastiCache used for?

Amazon ElastiCache improves the performance of web applications by allowing you to retrieve information from a fast, managed, in-memory system, instead of relying entirely on slower disk-based databases.

Can you cache data in Lambda?

There are a few ways in which we can cache within the lambda itself: 🔵 Cache within the Lambda runtime environment (in memory). 🔵 Cache within the /tmp folder on the Lambda. 🔵 Caching of secrets using the AppConfig Lambda Layer.

Why do we use Redis in Java?

Redis enables you to write traditionally complex code with fewer, simpler lines. With Redis, you write fewer lines of code to store, access, and use data in your applications. The difference is that developers who use Redis can use a simple command structure as opposed to the query languages of traditional databases.
