Great. Rumour has it there is some HOT transaction code in there, among other things.

We may find that that HOT transaction code is the same as our transaction code, which I guess would mean ours is HOT too. -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

I wonder when they implemented theirs? Basically...is their's based on
old technology/concepts, while ours is based on newer ones?

Reminds me of the guy who said our MVCC was a leader in database technology. He did not realize is was only one person, Vadim, who did the whole thing. Amazing when just one of our developers makes the commercial db's look like they are standing still. -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

Apparently they were formed out of DEC in 1985, with the notion of doing a "multi-generational" model from the beginning. I don't know enough Postgres history to answer. Obviously, MVCC is new but the way that tuples are stored, which made MVCC fairly simple to implement (for Vadim, at least!), has been part of Postgres from the beginning. And, again, my information on Interbase comes from a VERY quick read of docs and a white paper found on their site, take my quick-hit analysis with a grain of salt, please! - Don Baccus, Portland OR <dhogaza@pacifier.com> Nature photos, on-line guides, Pacific Northwest Rare Bird Alert Serviceand other goodies at http://donb.photo.net.

Maybe it's based on the same technology. If the've used a similar (HOT) transactional concept for tuples, based
legallyon the PG technique released under the BSD license years ago, they might have come to the same conclusion.
That'dmean - well - OLD concepts like ours.
Truth remains truth.

Yes, MVCC was natural for us. -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026
