In this blog, we’ll look at ICP counters in the information_schema.INNODB_METRICS. This is part two of the Index Condition Pushdown (ICP) counters blog post series.
As mentioned in the previous post, in this blog we will look at how to check on ICP counters on MySQL and Percona Server for MySQL. This also applies to MariaDB, since the INNODB_METRICS table is also available for MariaDB (as opposed to the Handler_icp_% counters being MariaDB-specific). We will use the same table and data set as in the previous post.
For simplicity we’ll show the examples on MySQL 5.7.18, but they …
[Read more]In this tutorial, I will show you step by step to configure MySQL securely for remote connections with SSL. MySQL is an open source relational database system that works on many Operating Systems including Windows, Linux, MacOS and FreeBSD. It is probably the most popular OpenSource RDBMS and a central component of the LAMP and LEMP Stacks.
Kristian Nielsen is working on a new feature for MariaDB 10.3 and he published very interesting results. This feature is MDEV-12179: Per-engine mysql.gtid_slave_pos tables. He writes about replicating twice as fast in the worst case when using two storage engines (InnoDB and MariaRocks in his tests, but could also be InnoDB and TokuDB or TokuDB and MyRocks). I will let you read all the details
In a perfect world, one would upgrade databases one version at a time and not let them get too old. But our databases are where the “crown jewels” are. They must stay up 24×7. When performance is acceptable, it’s acceptable, and sometimes old versions stay around too long. We don’t live in a perfect world. This idea applies to so many things. There’s almost never a perfect data model. There is always some type of resource constraint be it storage, memory, CPU, IOPS, or just plain dollars.
I will bring this concept of not living in a perfect world into a discussion about upgrades.
Ideally there would be…
Long time MySQL users will recognize that there are two varieties of utf8 support in MySQL; utf8mb3 and utf8mb4. Let me dig a little bit deeper in explaining the history between the two:

pt-table-checksum, …MySQL Cloud Service is a new(ish) way to run MySQL in the cloud, without worrying about installing the server yourself and configuring security, performance, or monitoring, because that's all taken care of by the service. This makes it great for setting up quick throwaway instances that you can just as easily tear down, and it's ideal for developers who don't want to get in line to wait for their DBAs to set up a server for them.
If you've got an account with Oracle Public Cloud (or even a trial account) that has MySQL Cloud Service enabled, it's only a few clicks to get an instance set up. Here's a short overview.
When you've got your instance, you can connect to it with several different …
