Why Aren't All Data Immutable?

Over the last few years there has been an increasing interest in immutable data management. This is a big change from the traditional update-in-place approach many database systems use today, where new values delete old values, which are then lost. With immutable data you record everything, generally using methods that append data from successive transactions rather than replacing them.  In some DBMS types you can access the older values, while in others the system transparently uses the old values to solve useful problems like implementing eventual consistency.

Baron Schwartz recently pointed out that it can be hard to get decent transaction processing performance based on append-only methods like append-only B-trees.  This is not a very strong argument against immutable data per se. …

Replicate from Oracle to Oracle, Oracle to MySQL, and Oracle to Analytics

Oracle is the most powerful DBMS in the world. However, Oracle's expensive and complex replication makes it difficult to build highly available applications or move data in real-time to data warehouses and popular databases like MySQL. In this webinar-on-demand you will learn how Continuent Tungsten solves problems with Oracle replication at a fraction of the cost of other solutions and with less

Tungsten University: Load a Vertica data warehouse with MySQL data


Continuent Tungsten offers real-time replication from MySQL to a variety of DBMS types including Vertica. In this Tungsten University webcast we will show you the details of setting up MySQL-to-Vertica replication, including the following topics:

Tungsten University

We have started a new series of webinars at Continuent that we call Tungsten University.  They provide education on Tungsten clustering and replication in handy one-hour chunks.  These are not sales pitches.  Our goal is to provide accessible education about setting up and operating Tungsten without any marketing fluff.

The first Tungsten University webinar entitled "Configure & provision Tungsten clusters" will take place on Thursday January 17th at 10:00 PST.  It will show you how to set up a cluster in Amazon EC2.  There will be a repeat on January 22nd at 15:00 GMT.  We usually record webinars, so you can look at them later as well. 
You do not have to be a customer to attend these …

Slides from Percona Live London and a Request

Percona hosted another excellent Percona Live conference this past December 3-4 in London.  It was my pleasure to deliver 3 talks including the first keynote following Peter Zaitsev.  Percona does a great job of organizing these conferences--this year's London conference was well attended and in an excellent location in Kensington.  My thanks to the entire Percona team for putting this together.

Here are the slides for my talks in case you would like to see them.

Typical “Big” Data Architecture

Here is the typical “Big” data architecture, that covers most components involved in the data pipeline. More or less, we have the same architecture in production in number of places[...]

MySQL to Vertica Replication, Part 2: Setup and Operation

As described in the first article of this series, Tungsten Replicator can replicate data from MySQL to Vertica in real-time.  We use a new batch loading feature that applies transactions to data warehouses in very large blocks using COPY or LOAD DATA INFILE commands.  This second and concluding article walks through the details of setting up and testing MySQL to Vertica replication.

To keep the article reasonably short, I assume that readers are conversant with MySQL, Tungsten, and Vertica.  Basic replication setup is not hard if you follow all the steps described here, but of course there are variations in every setup.  For more information on Tungsten check out the Tungsten Replicator project at site well as …

MySQL to Vertica Replication, Part 1: Enabling Real-Time Analytics with Tungsten

Real-time analytics allow companies to react rapidly to changing business conditions.   Online ad services process click-through data to maximize ad impressions.  Retailers analyze sales patterns to identify micro-trends and move inventory to meet them.  The common theme is speed: moving lots of information without delay from operational systems to fast data warehouses that can feed reports back to users as quickly as possible.

Real-time data publishing is a classic example of a big data replication problem.  In this two-part article I will describe recent work on Tungsten Replicator to move data out of MySQL into Vertica at high speed with minimal load on DBMS servers.  This feature …
