I talked today with Andy Astor, CEO of EnterpriseDB, and he confirmed that your view of their plans is inaccurate. Or maybe it’s your view of Greenplum that in my opinion is inaccurate. It will be a looooong time before EnterpriseDB supports more than the occasional data warehouse with >10 terabytes of user data. By way of contrast, the sweet spot of the data warehouse appliance market now is 5-30 Tb, and headed up quickly by another factor of 5.

Some vendors already aren’t very competitive below 30-50 Tb or so.

Though not all base their code on postgres.
We have 100% our own code base here at Scimore.com, with some intriguing features. E.g. horizontal scale out.

Anyone have an exhaustive list of the new rdbms up comers?

Please look at resources such as http://www.dbms2.com/2006/09/20/myths-datallegro-ingres-open-source/ or, perhaps even more to the point, Stuart Frost’s second comment on http://www.dbms2.com/2006/07/03/datallegro%E2%80%99s-technical-strategy/

DATAllegro doesn’t use the Ingres optimizer. DATAllegro query execution leaves Ingres multiple times during a typical query (because the Ingres instances run on single nodes only). There is no Ingres subsystem to DATAllegro’s software of which one can correctly say “Oh, Ingres is doing all the DBMSy parts, and what’s around is something other than a DBMS.” Any definition of “DBMS” under which Ingres is “the” DBMS on the DATAllegro appliance is not one I would endorse, and I suspect I’m in the large majority in using the term that way.

If it doesn’t build and execute the query plans, it’s not a DBMS to me. Ingres doesn’t do all of that for DATAllegro, so it’s not the whole DBMS.

Is this now clearer?

See http://datallegro.com/images/v3_node_large.jpg . Ingres is the DBMS on the DATAllegro appliance.

According to a Feb 2007 press release, “DATAllegro has used the Ingres open source database in its data warehouse appliance since 2004″: http://datallegro.com/pr/2_20_07_datallegro_ingres.asp .

Bizgres MPP is what Greenplum DB used to be called. That’s on all supported platforms: Linux and OSX in addition to Solaris. The company changed the name of their only commercial product to match the company’s own name. The company actually used to be known as Metapa and their product was originally called Metapa Cluster Database.

Look again at the DATAllegro technology.

And when you say “formerly known a Bizgres MPP”, are you talking about sales in conjunction with Sun, or something else?

- Netezza’s DBMS is a PostgreSQL fork.

- DATAllegro, to be precise, is an appliance rather than a DBMS, and Ingres is the DBMS on the appliance. Similarly, for precision’s sake: Infobright has created an engine that plugs into the MySQL framework, essentially an alternative to the MyISAM engine, which was formerly the best choice for analytical work.

- Greenplum appears to be doing quite well, with significant growth in paid customers for their Greenplum DB (formerly known as Bizgres MPP).

- EnterpriseDB has some intentions of rivaling Greenplum as an enhancement of PostgreSQL for data warehousing. They’d do this by integrating PostgreSQL MPP technology they acquired for ExtenDB last summer-fall.

- It of course would make sense for Vertica to “emulate” PostgreSQL given that Stonebraker was behind Postgres and is behind Vertica. Vertica is a commercialization of the open-source academic project C-Store, just as Illustra was a commercialization of mid-’90s Postgres.

I’m almost ready to put (figurative) pen to paper and write up the report on “open source (based) data warehousing” that I’ve been talking about for 5-6 months now.
