How to Deal with Triggers in Your Mysql Database When Using Tungsten Replicator

Overview

Over the past few days we have been working with a number of customers on the best way to handle Triggers within their MySQL environment when combined with Tungsten Replicator. We looked at situations where Tungsten Replicator was either part of a Tungsten Clustering installation or a standalone replication pipeline.

This blog dives head first into the minefield of Triggers and Replication.

Summary and Recommendations

The conclusion was that there is no easy one-answer-fits-all solution – It really depends on the complexity of your environment and the amount of flexibility you have in being able to adjust. Our top level summary and recommendations are as follows:

If using Tungsten Clustering and you need to use Triggers:

Comparing MySQL to Vertica Replication under MemCloud, AWS and Bare Metal

Back in December, I did a detailed analysis for getting data into Vertica from MySQL using Tungsten Replicator, all within the Kodiak MemCloud.

I got some good numbers towards the end – 1.9 million rows/minute into Vertica. I did this using a standard replicator deployment, plus some tweaks to the Vertica environment. In particular:

  • Integer hash for a partition for both the staging and base tables
  • Some tweaks to the queries to ensure that we used the partitions in the most efficient manner
  • Optimized the batching within the applier to hit the right numbers for the transaction counts

That last one is a bit of a cheat because in a real-world situation it’s much harder to be able to identify those transaction sizes and row counts, but for testing, we’re trying to get the best performance!

Next what I wanted to do was set up some bare metal and AWS servers that were of an …

MariaDB to Hadoop in Spanish

Nicolas Tobias has written an awesome guide to setting up replication from MariaDB to Hadoop/HDFS using Tungsten Replicator, in Spanish! He’s planning more of these so if you like what you see, please let him know!

Semana santa y yo con nuevas batallas que contar.
Me hayaba yo en el trabajo, pensando en que iba a invertir la calma que acompa;a a los dias de vacaciones que libremente podemos elegir trabajar y pense: No seria bueno terminar esa sincronizacion entre los servidores de mariaDB y HIVE?

Ya habia buscado algo de info al respecto en Enero hasta tenia una PoC montada con unas VM que volvi a encender, pero estaba todo podrido: no arrancaba, no funcionba ni siquiera me acordaba como lo habia hecho y el history de la shell er un galimatias. Decidi que si lo rehacia todo desde cero iba a poder dejarlo escrito en un playbook y ademas, aprenderlo y automatizarlo hasta el limite de poder desplegar de forma automatica on …

Tungsten Clustering 6.0 and Tungsten Replicator 6.0 are now available!

Continuent is very pleased and excited to announce that the new Tungsten Clustering 6.0 and Tungsten Replicator 6.0 are now available for download by our customers. The 6.0 release is the culmination of over a years work within our clustering product in order to improve the functionality and manageability of what we now call our ‘Multimaster Clustering’ solution. This is the replacement for what we called the multi-site, multi-master (MSMM) clustering functionality in earlier releases. The multimaster clustering allows for multiple clusters, in multiple locations, to be linked together into a single composite cluster. Because it’s a composite cluster, you gain all of the functionality that’s already available in a cluster, such as:

  • High availability
  • Failover
  • Automated recovery
  • Read-write split
  • Maintenance without downtime

But it’s now applied to the …

Analytical Replication Performance from MySQL to Vertica on MemCloud

I’ve recently been trying to improve the performance of the Vertica replicator, particularly in the form of the of the new single schema replication. We’ve done a lot in the new Tungsten Replicator 5.3.0 release to improve (and ultimately support) the new single schema model.

As part of that, I’ve also been personally looking to Kodiak MemCloud as a deployment platform. The people at Kodiak have been really helpful (disclaimer: I’ve worked with some of them in the past). MemCloud is a high-performance cloud platform that is based on hardware with high speed (and volume) RAM, SSD and fast Ethernet connections. This means that even without any adjustment and tuning you’ve got a fast platform to work on.

However, if you are willing to put in some extra time, you can tune things further. Once you have a super quick …
