+2 Vote Up -0Vote Down

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:

  • ft-index. This repository is the “magic”. It contains the Fractal Tree data structures we have been talking about for years. This is also the main piece that was previously closed source. Here are some …

MySQL Applier For Hadoop: Real time data export from MySQL to HDFS
Employee +2 Vote Up -0Vote Down


MySQL replication enables data to be replicated from one MySQL database server (the master) to one or more MySQL database servers (the slaves). However, imagine the number of use cases being served if the slave (to which data is replicated) isn't restricted to be a MySQL server; but it can be any other database server or platform with replication events applied in real-time! 
This is what the new Hadoop Applier empowers you to do.
An example of such a slave could be a data warehouse system such as …

Announcing TokuDB v7: Open Source and More
+3 Vote Up -0Vote Down

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 …

Deploying Cloudera Impala on EC2 with Example Live Demo
+0 Vote Up -0Vote Down

A little while ago I blogged about (and open sourced) an Impala-powered soccer visualization demo, designed to demonstrate just how responsive Impala queries can be. Since not everyone has the time or resources to run the project themselves, we’ve decided to host it ourselves on an EC2 instance. You can try the visualization; we’ve also opened up the Impala web interface, where you can see query …

They say: "Relational Databases Aren't Dead"
+2 Vote Up -0Vote Down

This is a good read, claiming: "Relational Databases Aren't Dead. Heck, They're Not Even Sleeping", http://readwrite.com/2013/03/26/relational-databases-far-from-dead. A key quote:

There were 2 parts in the statement about NoSQL's uses. I'll start with the latter:


"data that does not easily fit within uniform …

We had the opportunity to do a CUBE interview with Wikibon analyst Jeff Kelly at last week’s Strata Conference in Santa Clara. In the first part of our conversation, we discuss how our success in integrating Tokutek’s Fractal Tree® technology into MySQL has led us to another popular database, MongoDB. We explain the results of our recent benchmarking tests with MongoDB, which indicate that adding indexing can also …
