When using the replication slave stream, or mysql command line client and mysqlbinlog output from a binary/relay log, all statements are executed in a single thread as quickly as possible.

I am seeking a tool to simulate the replay of the binary/relay log for a benchmark at a pace that is more representative to original statements. For a simple example, if the Binary Log has 3 transactions in the first second, 2 transactions in the second second, and 5 transactions in the third second, I am wanting to simulate the replay to take roughly 3 seconds, not as fast as possible (which would be sub-second). The tool should try to wait the remainder of a second before processing SQL statements in the incoming stream.

Does anybody know of a tool that currently provides this type of functionality? Any input appreciated before I create my own.

As promised, this is the final post in a series looking at eventual consistency with MySQL Cluster asynchronous replication. This time I'll describe the transaction dependency tracking used with NDB$EPOCH_TRANS and review some of the implementation properties.

Transaction based conflict handling with NDB$EPOCH_TRANS

NDB$EPOCH_TRANS is almost exactly the same as NDB$EPOCH, except that when a conflict is detected on a row, the whole user transaction which made the conflicting row change is marked as conflicting, along with any dependent transactions. All of these rejected row operations are then handled using inserts to an exceptions table and realignment …

In order to benchmark a Drupal site performance you need to see all the database queries related to your Drupal site.

When Oracle acquired MySQL there was some concern about what would happen with the world's most popular open-source database.  It's clear now that not only is Oracle very serious about continuing the great database but it is expanding the teams working on it and it's related technologies.  I know because I run one of those teams!

I've been working on MySQL and .NET technologies for the past 8 years and I'm very proud to introduce a couple of people who have been and will continue be working on my team.
