I had lunch today with CTO Bob Zurek of EnterpriseDB, who turns out to live in almost the same town I do (they technically separated in 1783, but share a high school today). DBMS-related highlights included:
- EnterpriseDB thinks PostgreSQL training and certification are a big deal for increasing PostgreSQL adoption.
- EnterpriseDB’s business focus right now (at least, one of them) is moving developers from interest to download to deployment and payment — i.e., the standard funnel for open source and open-source-inspired products.
- EnterpriseDB finds it important to be a good PostgreSQL community citizen. This makes a lot of sense, as EnterpriseDB doesn’t control the core PostgreSQL engine, even if it does employ some of the core PostgreSQL developers.
- But “open source” is not the same as “free”.
- I got the impression that the GridSQL technology EnterpriseDB acquired is being used to go after general read-mostly, horizontally-scaling applications (i.e., MySQL’s sweet spot). I did not get the impression, by way of contrast, that EnterpriseDB is out to play catch-up — e.g., with GreenPlum — in MPP data warehousing.
- Bob pointed out that something like “Vacuum” to clean up the database periodically is needed in a MVCC (MultiVersion Concurrency Control) engine. He thinks PostgreSQL’s autovacuum is good but not ideal.
- Bob draws this as yet another two-dimensional positioning graph, but in essence he thinks PostgreSQL and Postgres Plus are well-suited for a large space that’s above MySQL and below Oracle. I don’t think he really contradicted Kee Kwan’s opinion that there are good times to use PostgreSQL and good times to use MySQL.
- I was wrong when I previously said EnterpriseDB now offers MySQL portability. It just offers MySQL migration.
- The Elastra/EnterpriseDB cloud offering isn’t generally available yet.
- Stay tuned for developments in replication/high availability.
- Kee Kwan’s views on when to use MySQL and when to use PostgreSQL
- Jignesh Shah on common PostgreSQL user questions
- A Network World blog post I did on PostgreSQL vs. MySQL, which spawned a lively comment thread
