MySQL Enterprise and MySQL HeatWave now support writing stored functions and procedures using JavaScript. In this post we show how to debug JavaScript code used to create stored functions.

Recently, I have written extensively about using JavaScript to create stored functions in MySQL. I have talked about searching, filtering, and sorting JSON array data. I have discussed using top-level JavaScript objects such as Intl and Math. Today, I will talk about debugging stored functions written in JavaScript. The Problem Debugging MySQL stored functions, even those written in SQL, can be arduous. […]

If you were to ask me the question, “Would it be possible to set up a replicate filter within the Percona XtraDB Cluster?” my immediate response would be to question you right back. Why would you even want the cluster nodes to have different data when you’re using a synchronous replication cluster? That’s because, instinctively, […]

 This is the fourth article in our series about MySQL NDB Cluster replication. We’ve now got so far into the details that data can not only be replicated from one cluster to the other but also back to the first again, we call this circular replication and it enables locating clusters in disparate places to […]

Learn about the two different strategies for setting up multi-primary bidirectional replication between MySQL NDB clusters. This functionality is commonly used for highly available (HA) clusters that requires continuous online operation and disaster protection.
