(Marcelo Altmann) I’m the kind of DBA that prefers to keep everything simple, BUT, sometimes it’s not possible. Few days ago I’ve faced an issue where none of the collations shipped by default with MySQL would guarantee integrity of my database, and to avoid a massive re-write of application code, w

(Stephane Combaudon) I have heard this question quite often: “At busy times, our replicas start lagging quite frequently. We are using N schemas, so which performance boost could we expect from MySQL 5.6 parallel replication?” Here is a quick way to give you a rough estimate of the potential benefit

(Giuseppe Maxia) In all-masters P2P topologies, we have seen that we have a way of deploying a topology where all nodes are masters, and achieve better efficiency and stability than ring topologies. That method comes at the price of a complex setup, which requires, for a N-node cluster, N*(N-1) conn

(Sunny Bains) Astute readers will note that InnoDB already had compression since the MySQL 5.1 plugin. We are using the terminology of ‘Page Compression’ to describe the new offering that will ship with MySQL 5.7, and ‘InnoDB Compression’ for the earlier offering.

(Giuseppe Maxia) In the previous article, we saw the basics of establishing replication from multiple origins to the same destination. By extending that concept, we can deploy more complex topologies, such as the point-to-point (P2P) all-masters topology, a robust and fast way of moving data.

(Shahriyar Rzayev) Today’s topic is related primarily to compiling MySQL from source using CMAKE and what kind of issues we encounter during this task.
