While working on a recent support issue as a Percona Support Engineer, I got one question from a customer asking how to monitor ALTER TABLE progress. Actually, for MySQL 5.5 and prior versions, it’s quite difficult to ALTER the table in a running production environment especially for large tables (with millions records). Because it will rebuild and lock the table affecting the performance as well as our users.
I’ve mentioned InfiniDB before in a previous post titled, “Star Schema Bechmark: InfoBright, InfiniDB and LucidDB,” but it’s been 4 years since that was published. Recently I evaluated column-storage solutions for Percona Cloud Tools and took another look at InfiniDB 4. There was the release of version 4, which I think is worth attention.
Percona is glad to announce the release of Percona Toolkit 2.2.7 on February 24th, 2014 (Downloads are available here and from the Percona Software Repositories). This release is the current GA (Generally Available) stable release in the 2.2 series. This release fixes one security bug. An upgrade is recommended.
In my previous post I pointed out that the existing
ARCHIVE storage engine in MySQL may not be the one that will satisfy your needs when it comes to effectively storing large and/or old data. But are there any good alternatives? As the primary purpose of this engine is to store rarely accessed data in disk space efficient way, I will focus here on data compression abilities rather then on performance.
In the last few years of my career, I’ve increasingly been involved in meeting
people. This often involves requests or offers for recommendations,
introductions, and so forth.
I’ve learned to be very careful about making or accepting such offers or
requests, and I’d like to share my current thoughts about that with you, because
a lot of trouble can come of a seemingly innocent request or offer.
Many startups depend on MySQL. Check out the list of keynote speakers from past and present MySQL User Conferences. There are things to make better and new features to add like better support for dynamic schemas (documents) and auto-sharding. But existing deployments aren't in crisis mode and it is being used for new deployments. Maybe I have an agenda in writing this but anyone writing the opposite is likely to have their own agenda.
Percona is glad to announce the new release of Percona XtraDB Cluster 5.6 on February 20th 2014.
