Read this article on my new blog As part of my on-boarding/training at RedisLabs I continue to play with the product, and I have decided today to install a local 3 nodes cluster of Redis Enterprise Server (RS); and show how easy is to move from a single node/shard database to a multi nodes highly available one. Once your cluster is up & running, you will kill some containers to see how Tug Grallhttp://www.blogger.com/profile/12028480831632266604noreply@blogger.com0

Read this article on my new blog As you may have seen, I have joined Redis Labs a month ago; one of the first task as a new hire is to learn more about Redis. So I learned, and I am still learning. This is when I discovered Redis Streams. I am a big fan of streaming-based applications so it is natural that I start with a small blog post explaining how to use Redis Streams and Java.

This is different from the automatic and intra-cluster replication that copies the data into different physical nodes for high availability and prevent data loss.
