Oracle’s website shows End of life for MySQL 5.5 as of Jan 20th of 2019, so hurry up and upgrade!

I am working building some demos for Cloud SQL and one of the requirements I had was to run MySQL 5.7 and WordPress as my sample application. The demo consisted on migrating from a single VM environment with WordPress and MySQL running alongside. The narrative: the site got popular and the database became the bottle neck because of all the shared resources between them and the application. The proposed solution? A minimal downtime migration to Cloud SQL, moving the data layer to a dedicated server.

I am going to be doing this demo a lot of times, so I needed some way to automate it. I thought of doing through Docker. I am not Docker proficient, and to begin with I asked …

Recently we had a customer who came to us for help with monitoring their InnoDB cluster setup. They run a 5.7 InnoDB cluster and suffered from a network outage that split up their cluster leaving it with no writeable primaries. As part of their incident followup, they asked us for methods to monitor this cluster.

I had tested before with InnoDB clusters (in both 8.0 and 5.7 variants) and I was confident that we could parse the cluster node “role” (read-write aka primary vs. read-only aka secondary) from the performance_schema tables. As it turned out, this feature is not in 5.7 but only 8.0. However, the docs on this are wrong for 5.7 as these docs suggest that the performance_schema.group_replication_members table would show PRIMARY and SECONDARY role of each cluster node. I have submitted a …

The post MySQL With DevOps 1 – Automate Database Archive appeared first on SQLgossip.

This is my next blog series. Im going to write about how I automated many complex tasks in MySQL with Rundeck. In my last series, I have explained RunDeck basics. You can find those articles here. In this blog Im writing about how I automated MySQL archive for multiple tables in one Rundeck job.

Challeange with Replication:

My MySQL database setup has 1 Master 4 Read Replica and the 3’rd replica is an intermediate Master for Replica 4. I don’t want to archive this data on Replica 3 and 4. Because these replicas are using for generating historical reports also some internal application.

Disable Log-Bin:

To prevent archive data on Replica 3 and 4, I decided to disable binlog on my archive session. But another challenge is, it won’t replicate to Replica 1 and 2. So my final solution is Archive the data on Master, then execute the …

Dear MySQL users,

MySQL Connector/Node.js is a new Node.js driver for use with the X
DevAPI. This release, v8.0.15, is a maintenance release of the
MySQL Connector/Node.js 8.0 series.

The X DevAPI enables application developers to write code that combines
the strengths of the relational and document models using a modern,
NoSQL-like syntax that does not assume previous experience writing
traditional SQL.

MySQL Connector/Node.js can be downloaded through npm (see
https://www.npmjs.com/package/@mysql/xdevapi for details) or from
https://dev.mysql.com/downloads/connector/nodejs/.

To learn more about how to write applications using the X DevAPI, see
