Thanks to all of those who came to the lightning talks this evening. We’ve got the audio posted here and the lyrics below.
Since we announced that TokuDB is now open source, there has been a lot of positive feedback (thanks!) and also some questions about the details. I want to take this opportunity to give a quick high level guide to describe what our repositories on Github are.
Here are the repositories:
I enjoyed Stewart Smith’s MySQL storage engine blog last week. In it he noted “I cannot emphasize how much more interesting TokuDB would be if it were open source.” Well, with our open source announcement yesterday, hopefully we are getting interesting.
We wanted to thank everyone for the great feedback. Here is a sampling from some of the forums where dialogue is occurring:
For me, the biggest news in the last 24 hours so far has been:
Every few months, I get the fun job of announcing what’s new in TokuDB®, but this time is special. With Version 7, TokuDB for MySQL and MariaDB is going open source.
The free Community Edition is fully functional and fully performant. It has all the compression you’ve come to expect from TokuDB. It has hot schema changes: no-down-time column insertion, deletion, renaming, etc., as well as index creation. It has clustering secondary keys. We are also announcing an Enterprise Edition (coming soon) with additional benefits, such as a support package and advanced backup …[Read more...]
If T.S. Eliot were a MySQL DBA, I think he would have been more upbeat about April.
We are gearing up for an incredible second half of April. We will be presenting three separate sessions at the Percona Live: MySQL Conference and Expo 2013, April 22-25, in Santa Clara, CA. In addition, we will be presenting at SkySQL’s MySQL & Cloud Database Solutions Day on Friday, April 26 at …[Read more...]
Earlier, I talked about the transactional semantics we are introducing to MongoDB. As I hinted at the end of the post, we are actually doing more. We are introducing multi-statement transactions. That’s right, multiple queries, updates, deletes, and inserts will be able to run inside of a single transaction. We are working on the details of the semantics as we develop our beta, but at a high level, think of it as having the same semantics as TokuDB and InnoDB’s multi-statement transactions in MySQL.
So how will it …[Read more...]
People claim that MongoDB is not transactional. It actually is, and that’s a good thing.
In MongoDB 2.2, individual operations are Atomic. By having per database locks control reads and writes to collections, write operations on collections are Consistent and Isolated. With journaling on, operations may be made Durable. Put these properties together, and you have basic ACID properties for transactions.
The shortcoming with MongoDB’s …[Read more...]
Last month my colleague Rich Prohaska covered the technical details of our “Fast Update” feature which we added to TokuDB in version 6.6. The message based architecture of Fractal Tree Indexes allows us to defer certain operations while still maintaining the semantics that MySQL users require.
In the case of Fast Updates, TokuDB is avoiding the read-before-write requirement that the …[Read more...]
