MariaDB and MySQL. Are they syntactically similar? Where do these two query languages differ? Why would I use one over the other?

MariaDB is on the path of gradually diverging from MySQL. One obvious example is the internal data …

AWS recently announced the release of MariaDB 10.2 for RDS. One of customer needs this release for GIS indexing .The recent encounter on a Replication issue with RDS MariaDB 10.2 is briefed here .

Problem Statement:

After the upgrade of replicas to MariaDB 10.2 on RDS, Once replication is stopped manually through “call mysql.rds_stop_replication;” or replication failed due to some error. Replication cannot be started back using “call mysql.rds_start_replication;” and there is no straightforward way or documented process to start the replication back. Also, most of the replication related RDS commands like skip errors etc will not work. This is due to the implementation of replication handling in RDS.

Summary:

On Jan 5, 2018, RDS announced support for MariaDB 10.2.  …

Much is still being talked about the Meltdown/Spectre CPU security vulnerabilities. There’s an interesting Twitter thread showing performance impact on Kafka brokers. Jaime Crespo also writes about how it affects MariaDB Server 10.1.30 – Finding out the MySQL performance regression due to kernel mitigation for Meltdown CPU vulnerability. It’s worth checking out the thread for PostgreSQL too.

Something else worth thinking about, …

Happy New Year. Here’s to 2018 being a great year in the open source database world. What is in store for us? Probably: MySQL 8.0 and MariaDB Server 10.3 as generally available. What will we see in the rest of the space? Clouds? All I know is that we move fast, and it’s going to be fun to see what unfolds.

The biggest news this week may not necessarily be database related; it focused on CPU security vulnerabilities and the potential slowdowns of your servers once the updates are applied. Please do read Meltdown and Spectre: CPU Security Vulnerabilities. Peter Zaitsev himself, got quoted in …

Update: I included the results for when PCID is disabled, for comparison, as a worse case scenario.

After learning about Meltdown and Spectre, I waited patiently to get a fix from my OS vendor. However, there were several reports of performance impact due to the kernel mitigation- for example on the PostgresQL developers mailing list there was reports of up to 23% throughput loss; Red Hat engineers report a regression range of 1-20%, but setting OLTP systems as the worse type of workload. As it will be highly dependent on the hardware and workload, I decided of doing some test myself for the …

The end of the year is upon us, and this column is being penned a little earlier than usual as I enjoy a quick bout of wrapping up for the year.

We’ve had a lot of things happen in the database world. It’s clear that open source is everywhere, the cloud is large, and we’ve seen a lot of interesting movements in our MySQL world, from the standpoint of corporate contributions too. GitHub continues to enhance Orchestrator, and gh-ost keeps on getting better; Facebook has ensured MyRocks is now mainstream in both MariaDB Server and Percona Server for MySQL distributions; Alibaba Cloud and Tencent have been contributing to make MariaDB Server better. …
