Migrating/importing NDB to Cluster Manager w/ version upgrade.

I’ve had some questions from people using MySQL Cluster GPL and wanting to move to using MySQL Cluster Carrier Grade Edition, i.e., they want to use MySQL Cluster Manager, MCM, to make their lives much easier, in particular, upgrading (as well as config change ease and backup history).

All I want to do here is to share with you my personal experience on migrating what’s considered a ‘wild’ NDB Cluster to a MCM managed cluster. It’s just as simple to follow the manual chapter Importing a Cluster into MySQL Cluster Manager so at least you can see how I did it, and it might help someone.

[ If you’re not migrating but just looking for further information on NDB Cluster, and came across this post, please please PLEASE look at the …

Kafka Replication from MySQL and Oracle

Hello again everybody.

Well, I promised it a couple of weeks ago, and I’m sorry it has been so long (I’ve been working on other fun stuff in addition to this). But I’m pleased to say that we now have a fully working applier that takes data from an incoming THL stream, whether that is Oracle or MySQL, and converts that into a JSON document and message for distribution over a Kafka topic.

Currently, the configuration is organised with the following parameters:

  • The topic name is set according to the incoming schema and table. You can optionally add a prefix. So, for example, if you have a table ‘invoices’ in the schema ‘sales’, your Kafka topic will be sales_invoices, or if you’ve added a prefix, ‘myprefix_schema_table’.
  • Data is marshalled into a JSON document as part of the message, and the structure is to have a bunch of metadata and then an embedded record. You’ll see an …
