InnoDB holepunch experiments

After excellent blogs by Mark Callaghan (see links below), I decided to use some of my time to experiment how different filesystems behave if the holepunch feature is used in MariaDB 10.1. First of all, MariaDB 10.1 does not use holepunch by default even if a table is page compressed (a term used in MariaDB). The holepunch feature in MariaDB is enabled with the innodb-use-trim=1 configuration variable and naturally requires support of the fallocate system call with the FALLOC_FL_PUNCH_HOLE and FALLOC_FL_KEEP_SIZE parameters. Support for these is checked during the cmake build phase.

I used CentOS Linux release 7.1.1503 (Core) using the 3.10.0-229.el7.x86_64 Linux kernel and few SSD drives in a RAID-0 setup (Intel X25-E Extreme SSDSA2SH032 G1GN 2.5-inch 32GB SATA II SLC Internal Solid State Drive (SSD)). …

MariaDB Connector/J has evolved a lot during the year. In this post I will talk about the failover capabilities in the connector and give some guidance on how to use them in some certain cases. One other important new feature that I’ll cover in a later article is the fact that MariaDB Connector/J can do load balancing over several servers now as well.

To start off with we’ll need the connector itself. Do either of the following to get version 1.2.3 of MariaDB Connector/J which is the newest stable version as of writing:

When you have read my previous blog post about MariaDB 10.1 GA performance, you have probably wondered why I didn’t include any numbers for MySQL 5.7. There are two reasons: first MySQL wasn’t GA at that time and secondly MySQL is not running stable on Power8.

Today I will come up with a comparison benchmark. I have chosen some more down-to-earth hardware for that because that is what the majority of our users will be running. Specifically it’s a SP-64 cloud machine from OVH. It has a 4-core Intel CPU and 64G of RAM. Disks aren’t fancy, but the benchmark is again a simplified read-only OLTP workload that runs from memory. …

MariaDB 10.1 shipped a few days ago, so it’s now a good time to focus on another important event. Last week we had a three day MariaDB developers meeting. It took place in Amsterdam (Oct 13-15). Meetings like this tend to have a great impact on the roadmap of the product. Booking.com was very kind to offer their facilities for the developer meeting.

Thank you Booking.com!

The day before the developer meeting there was a MySQL meetup arranged at eBay’s office in Amsterdam since, naturally, a lot of MariaDB developers were already in town for the developers meeting. …

With the release of 10.1.8, MariaDB takes a next step. MariaDB 10.1 is now considered a stable release.

MariaDB 10.1 has a couple of main themes:

Security
High Availability
Scalability

During the last few years there have been many request for more security features in MariaDB. Actually it’s a trend in general. Since open source software is getting more attractive all the time, more functionality is wanted in areas where proprietary software typically has been leading. This is especially true for databases. In addition data privacy is a very hot topic.

The big new thing in security for MariaDB 10.1 is a complete data at rest encryption solution. …
