Multi-channel replication is one of the  great feature shipped with MySQL 5.7, With allowed the capability of slave to have many masters, having a channel for each master by which they replicate. Each channel id has a unique “channel_name”

Multi-Channel Replication

In the above DB Architecture “channel_1, channel_2 and channel_3” represent the channel_name used for replication from different MySQL servers ( Source ). In this blog we are not going see about configuration of multi_source replication, rather we are going to see about rolling back multi-source replication in MySQL. Recently we were working on a client, where we had deployed multi-channel replication replication from two master onto a single slave, sync was happening very fine Then came the situation to break the replication from …

The schedule of the next edition of the MySQL & Friends Devroom is now on-line also on the official FOSDEM website.

As you can see we by shrinking the last two talks (no break) we were able to add one extra session. The committee selected the next one, which mean I will have the honour to present again at FOSDEM too.

It was a long time ago so I won’t write about the conference (it was good as always), but at least I share the slides of my talk here.

We had a really great session yesterday during the webinar on Amazon Redshift replication, but sadly ran out of time for questions. So as promised, let’s try and answer the questions asked now!

Are you going to support SAP IQ as a target ?

This is the first request we’ve ever received, and so therefore there are no firm plans for supporting it. As a target, SAP IQ supports a JDBC interface, and therefore is not hugely complicated to achieve compared to more complex, customer appliers.

Can you replicate from SAP ASE ?

No, and no current plans.

What about latin1 character ? Is it supported ?

Yes, although the default mode is for us to use UTF-8 for all extract and apply jobs. You can certainly change the character set, although leaving UTF-8 should also work.

Is it a problem not to have primary keys on Redshift ? …

Fill out a quick survey on your cloud data plans.

Today, keeping your enterprise agile and flexible is not just an advantage, it is a requirement. Many of the systems and processes once controlled by businesses onsite are moving offsite to “service” models. This includes Platform as a Service (PaaS), Software as a Service (SaaS), Infrastructure as a Service (IaaS), Database as a Service (DBaaS), etc.

These services are usually referred to as being in the cloud. The enterprise using the service doesn’t maintain or manage the infrastructure of the service in question.

Migrating database workloads to the cloud can be a vital part of improving customer experience, gaining deeper business insights and increasing efficiency. More enterprises are …

In this blog post, we’ll look at how sequence numbers work in Percona XtraDB Cluster.

Introduction

Percona XtraDB Cluster uses multiple sequence numbers (seqno), each having a special role to play. Let’s try to understand the significance of each sequence number.

global_seqno

An active Percona XtraDB Cluster cluster has multiple write-sets (transactions) generated from one or more nodes. These transactions then get replicated to other nodes of the cluster. Each write-set/transaction should have a unique identity across the cluster. global_seqno helps serve this identity. Given write-set will have the same global_seqno on …
