OK, here's my problem, I have a nature study where we have about 10 video cameras taking 15 frames per second. For each frame we make a few transactions on a PostgreSQL database. We want to keep about a years worth of data at any specific time. We have triggers that fire is something interesting is found on insert. We want this thing to run for a log time. >From the numbers, you can see the PostgreSQL database is VERY loaded. Running VACUUM may not always be possible without losing data. The numbers I have amount to 466,560,000 transactions per month, lasting a maximum of about 9 months until XID wrap.
I am thinking about a few work arounds, BEGIN/COMMIT to reduce the number of transactions, COPY, etc. so I'm not dead in the water, but I would be interested in any observations yo may have. ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
