How Clustrix does distributed SQL (It's impressive) (opens in new tab)

For anyone else interested in Clustra: Sun used to have decent HADB docs and whitepapers on bigadmin, but I can't find them any more in the new Oracle world. The two Sun projects that used HADB were Glassfish (clustered fault-tolerant app server, used HADB for session persistence data) and Honeycomb (clustered fault-tolerant archival storage, used HADB for metadata). Examples of how these systems used Clustra are on the web; in both cases the database size was small.

You mean the Clustra that was acquired by Sun and renamed HADB? I used it, and as far as I can remember, the HADB fault-tolerant story was that each node has a mirror that takes over if the first fails; and it's basically all in-memory. The Clustrix redundancy granularity is much finer, and everything is on disk.

As far as I know, no has a system like ours that can actually scale OLTP workloads. Warehousing/Analytics databases are very different beast. Can you point me at an OLTP system that I can expand without taking any loss of availability? How about supporting online schema changes?

Infiniband ports cost less than 10GE right now. There's really nothing that ties our architecture to IB. It's all about price/performance. When a better/cheaper technology becomes more available, we'll switch to that.

And we're always looking to hire good engineers with skills in distributed systems development.
