More Cores or Higher Clock Speed?
+0 Vote Up -0Vote Down

This is a little quiz (could be a discussion). I know what we tend to prefer (and why), but we’re interested in hearing additional and other opinions!

Given the way MySQL/MariaDB is architected, what would you prefer to see in a new server, more cores or higher clock speed? (presuming other factors such as CPU caches and memory access speed are identical).

For example, you might have a choice between

  • 2x 2.4GHz 6 core, or
  • 2x 3.0GHz 4 core

which option would you pick for a (dedicated) MySQL/MariaDB server, and why?

And, do you regard the “total speed” (N cores * GHz) as relevant in the decision process? If so, when and to what degree?

For this release, there are 4 “Functionality Added or Changed” items:

  • Functionality Added/Changed: CMake support was updated to handle CMake version 3.1.

MySQL 5.5.43 was recently released (it is the latest MySQL 5.5, is GA), and is available for download here:

http://dev.mysql.com/downloads/mysql/5.5.html

This release, similar to the last 5.5 release, is mostly uneventful.

There were only 2 “Functionality Added or Changed” items this time, and 10 additional bugs fixed.

Out of the 10 bugs, there was 1 InnoDB bug, 1 replication bug, and 6 crashing bugs, all of which seemed rather minor or obscure. Here are the ones worth noting:

  • Functionality Changed: CMake support was …

Keep your MySQL data in sync when using Tungsten Replicator
+1 Vote Up -0Vote Down

MySQL replication isn’t perfect and sometimes our data gets out of sync, either by a failure in replication or human intervention. We are all familiar with Percona Toolkit’s pt-table-checksum and pt-table-sync to help us check and fix data inconsistencies – but imagine the following scenario where we mix regular replication with the Tungsten Replicator:

We have regular replication going from master (db1) to 4 slaves (db2, db3, …
