Database Bigwigs Lead Stealthy Open Source Startup
BobB writes "Michael Stonebraker, who cooked up the Ingres and Postgres database management systems, is back with a stealthy startup called Vertica. And not just him, he has recruited former Oracle bigwigs Ray Lane and Jerry Held to give the company a boost before its software leaves beta testing. The promise — a Linux-based system that handles queries 100 times faster than traditional relational database management systems."
The article mentions that redhat and hp are listed among their partners. i'm not surprised by red hat or informatica (another partner though they aren't mentioned in the article) but i was a little surprised by hp - since they have been trying to get the word out about their own data warehousing and bi stuff. i wonder what that indicates about how they regard this new player.
also interesting is the wikipedia article on Michael Stonebraker if you aren't already familiar with him.
It's hard to believe that's how Micronians are made. Why don't we see it right now by having you both kiss one another?
KX is primarily in-memory. The competing column-oriented product is primarily Sybase IQ, which has been on the market for a while now.

It's basically an optimization of the current data access patterns. Databases have been row-oriented for decades, because they evolved from fixed width flat files. Once we eliminated COBOL-style accesses to databases, the full row data became less important. It became far more important to be able to scan a column as fast as possible. For example:
select * from names where lastname LIKE '%son'
The above query might have an index available to find what it needs. But it's just as likely that the database will need to do a table-scan. Since table-scans involve looking through every record in the database, you can imagine that it would be faster to just load the lastname column rather than loading every row in the database just to discard 90% of that data.

I noticed that Stonebraker is the company founder. Stonebraker has contributed extensively to database research over the years.
He's known for advocating the "shared-nothing" approach to parallel databases. The shared-nothing approach means that nodes in the parallel database don't attempt memory or cache synchronization, and each node has its own commodity disk array. In a shared-nothing parallel database, the data is "partitioned" across servers. So, for example, rows with id's 1-10 would be on the first server, 11-20 on the second server, etc. Executing the SQL query "select * from table where id < 1000" would send requests to multiple commodity servers and then aggregate the results. The optimizer is modified to take into account network bandwidth and latency, etc.
My guess on what they're doing: they're working on a shared-nothing parallel RDBMS with an in-memory client similar to Oracle TimesTen.
The are a few drawbacks to the shared-nothing approach: 1) the RDBMS software is more difficult to implement; 2) since the data is partitioned, any transaction that updates tuples on more than one database node requires a two-phase distributed commit, which is much more expensive; and 3) some queries are more expensive because they require transmitting large amounts of data over the network rather than a memory bus, and in rare cases that network overhead cannot be eliminated by the optimizer.
The advantage, of course, is linear scalability by adding commodity hardware. No more need for $3M+ boxes.

From the paper:
Among the many differences in its design are: storage of data by column rather than by row, careful coding and packing of objects into storage including main memory during query processing, storing an overlapping collection of columnoriented projections, rather than the current fare of tables and indexes, a non-traditional implementation of transactions which includes high availability and snapshot isolation for read-only transactions, and the extensive use of bitmap indexes to complement B-tree structures
By which I am asking that while Vertica is obviously well-researched and well funded as a start up, MonetDB is well-researched, already benchmarked and available now.. So why would I wait to invest my time, energy, and $$ in a proprietary future product rather than the time and energy, etc. to develop market leadership in my chosen corporate area in the present?
...Open Source isn't the only answer -- but it's almost always a better value than the alternatives...
Buzzwords, yes, but they have a little bit of meaning left. Grid-enabled means that it works on a "shared nothing" environment, that you can use a networked cluster of commodity computers if one isn't enough to hold the data, and so on. This is in contrast to using one big huge box (big computer, big storage array, or whatever). Of course many databases are similarly grid-enabled. Column-oriented means that data is stored on disk by column, this makes it fast to process a subset of columns that touch lots of rows, as is typical in data warehouse applications. This is a key architectural difference among databases; Oracle, DB2, etc., are "row stores", while Sybase IQ, Vertica, etc. are "column stores". Note: I work for Vertica Systems
Grid enabled - This means the DBMS can make use of a large distributed group of computers and potentially have access to a huge amount of computing power. The typical DBMS runs on at beat a multi-processor server. Thi sis kind of like a DBMS server running a a "seti at home" type network.
Going solely by the developer's reputation, this could be a big deal. He is not some random hacker. He is a well known university professor who has several times in the past lead projects that have been revolutionary and turned the field around. His ideas are widely used Still "100X faster" is a big claim. Lots of smart people have been working on DMBSes for many years, a two order of magnitude improvement is a "I will have to see it to believe it" type claim
I'm using PostgreSQL to handle some telemetry data right now. If my 45 minute run times can be reduced to seconds, I'll be happy.

This looks like it will be a commercial version of the Michael Stonebraker and MIT developed C-Store column-oriented:
- Web site: http://db.lcs.mit.edu/projects/cstore/
- Wikipedia Entry: http://en.wikipedia.org/wiki/C-Store
They distribute the source with a fairly liberal license, so this looks like something the open source community could pick up and run with.
