Fast Updates : Coming Soon in TokuMX v2.0

 | September 29, 2014 |  Posted In: Tokutek, TokuView

Coming in TokuMX v2.0 is a feature we’re calling “Fast Updates”. Fast updates permit certain update operations to bypass the read-modify-write behavior that most databases require (including MongoDB and the current release of TokuMX). In this blog I’ll cover how Fast Updates work by describing a simple schema and workload, plus I’ll measure the performance […]

TokuDB Read Free Replication : Details and Use Cases

 | September 25, 2014 |  Posted In: Tokutek, TokuView

The biggest innovation in TokuDB v7.5 is Read Free Replication (RFR). I blogged a few days ago posting a benchmark showing how much additional throughput can be achieved on a replication slave, while at the same time lowering the read IO operations to almost zero. The official documentation on the feature is available here. In […]

TokuDB v7.5 Read Free Replication : The Benchmark

 | September 23, 2014 |  Posted In: Tokutek, TokuView

New to TokuDB® v7.5 is a feature we’re calling “Read Free Replication” (RFR). RFR allows TokuDB replication slaves to process insert, update, and delete statements with almost no read IO. As a result, the slave can easily keep up with the master (no lag) as well as brings all the read IO capacity of the […]

Why TokuMX Changed MongoDB’s Oplog Format for Operations

 | June 5, 2014 |  Posted In: Tokutek, TokuView

Over several posts, I’ve explained the differences between TokuMX replication and MongoDB replication, and why they are completely incompatible. In this (belated) post, I explain one last difference: the oplog format for operations. Specifically, TokuMX and MongoDB log updates and deletes differently. Suppose we have a collection foo, with the following element:

We perform […]

Thoughts on Small Datum – Part 1

 | April 18, 2014 |  Posted In: Tokutek, TokuView

A little background… When I ventured into sales and marketing (I’m an engineer by education) I learned I would often have to interpret and simply summarize the business value that is sometimes hidden in benchmarks. Simply put, the people who approve the purchase of products like TokuDB® and TokuMX™ appreciate the executive summary. Therefore, I plan […]

Why TokuMX Replication Differs from MongoDB Replication

 | March 24, 2014 |  Posted In: Tokutek, TokuView

MongoDB replication has some great features. As I discussed in my last post, MongoDB’s crash safety design is very elegant. In addition to that, MongoDB has automatic failover, parallel slave replication, and prefetch threads on secondaries. The latter, as Mark Callaghan points out, is similar to “InnoDB fake changes”, a feature that has helped Facebook […]
