We had a great webinar on Wednesday looking at how we can use Tungsten Replicator for moving data into Elasticsearch, whether that’s for analytics, searching, or reporting.

You can ahead and watch the video recording of that session here

We had one question on that session, which I wanted to answer in full:

Can UPDATE and DELETE be converted to INSERT?

One of the interesting issues with replicating databases between databases is that we don’t always want the information in the same format when it goes over another side. Typically when replicating within a homogeneous environment the reason we are using replication is that we want an identical copy over on the other side of the process. In heterogeneous, especially when we move the data out to an analytics environment like Elasticsearch, we might not. That covers a whole range of …

I think the biggest news from last week was from cPanel – if you haven’t already read the post, please do – on Being a Good Open Source Community Member: Why we hesitated on MySQL 5.7. cPanel anticipated MariaDB being the eventual replacement for MySQL, based on movements from Red Hat, Wikipedia and Google. The advantage focused on transparency around security disclosure, and the added features/improvements. Today though, “MySQL now consistently matches or outpaces MariaDB when it comes to development and releases, which in turn is increasing the demand on us for providing those upgraded versions of MySQL by our users.” And …
