InnoDB file per table dilemma
+0 Vote Up -0Vote Down

I have recently decided I would like to take advantage of the benefits of InnoDB file-per-table. Namely, that OPTIMIZE TABLE benefits-- defragmentation (Grazr does a lot of writes, both INSERT and DELETE), .ibd files being able to shrink if optimized, etc.

So, the next question is how to convert a ton of data to this setup. What I have tried is this:

1. Add innodb_file_per_table to my.cnf
2. Restart MySQL
3. Alter all InnoDB tables engine=InnoDB

This works great... except, my two 10GB tablespace files remain. I would like to make them smaller, but there is no way of doing this.

Also, there is no trick where you …

The new kid on the block - Drizzle
+0 Vote Up -0Vote Down

Before today, Drizzle was known as a light form of rain found in Seattle (among other places). Not any more. If you have not read the news already today, Drizzle, Clouds, “What If?” is the new kid on the RDBMS bock.

Faster, leaner and designed with the original goals of ease-of-use, reliability and performance, Drizzle will make an impact in those organizations that are seeking a viable database storage solution for large scalable applications. The key to Drizzle is several fold. First, the crud has been removed. The first part of Drizzle development is to remove bloat or …

The pursuit of a synchronous world
+0 Vote Up -0Vote Down

Well at least your MySQL database world.

As Paul eluded to, PrimeBase Technologies has a project to provide synchronous replication for MySQL in a High Availability environment. It is more then an idea, there is a plan.

Is it possible?
What are the use cases?
How can you use it?
Would you use it?

Some input to date. We need these questions and more, and we seeking more input for discussion.

Unfortunately the opportunity to hear any input during a presentation is left to the last day of the conference, so we have created a BoF …

Storage Engines at the MySQL Conference
+0 Vote Up -0Vote Down

I’ll be following closely the progression of Storage Engines available in the MySQL Database server, well soon to be available when 5.1 gets to GA (hopefully by end of Q2 which is what we have been told). Tick, Tick, time is running out.

PrimeBase XT (PBXT) and Blob Streaming is obviously my clear focus, actually now working for PrimeBase Technologies, the company which I want to note for people is an Open Source company, committed at providing an open source alternative to the other commercial players. You also have at the …

FederatedX Pluggable Storage Engine Released!
+0 Vote Up -0Vote Down

The initial release of the FederatedX Pluggable Storage Engine for MySQL is now
available. I developed the Federated Storage Engine when I worked at MySQL,
and really saw a lot of potential with it. However, there were many other
projects that I had to give attention to, and many features and bug fixes that
users wanted didn't come into fruition because of the busy schedule. I left
MySQL a year ago to pursue an opportunity with Grazr what has kept me equally
busy. However, I have made a resolution this year to give some projects that I
have wanted to improve the attention that they need. I still see a lot of
potential with the …

Building a Storage Engine: Reading Data
+0 Vote Up -0Vote Down

Now that you can load an engine, we are going to look at reading data. For this we will need to implement three methods. We will also need the following schema:

CREATE TABLE `services` (
`a` varchar(125) NOT NULL DEFAULT '',
`b` text

Storage engines provide "handler" objects that are used to read/write/update tables. They inherit from the handler class defined in sql/handler.h.
The file holds the implementation of the handler for the Skeleton engine. Once a handler object is created it is cached and can be used for different tables that a particular storage …

Archive Storage Engine and Reporting
+0 Vote Up -0Vote Down

So I’ve been looking into the Archive Storage Engine. What I would really like to do with it is get data in realtime, because (of course) the higher-ups want reports on realtime data — that is, they are not satisfied with a report that is run regularly, they want all the data up until “now”.

It is inadvisable to replicate from one storage engine type to another. I have not yet played with it, but since an Archive table doesn’t allow updates and deletes, replicating from a MyISAM or InnoDB table to an Archive one is a bad idea.

Most folks probably run a batch job; but I wonder if it can be done in real-time. Or rather, ‘what is the best way to run it real-time?’ One …
