[REBOL] Handling very large databases

From: chris::starforge::co::uk at: 19-May-2001 10:25

Hi, I'm probably missing something obvious here, but anyway: say I have a file containing a meg or so worth of [string! date! integer! string! ...] [string! date! integer! string! ...] ... and I need to display blocks 120 to 135. Loading the whole file into memory just for a few blocks in the middle of the file is obviously a waste of time and resources. As this is a cgi script, and my hoster gets a but steamed if scripts lock up the system for too long, I would like to optimise this case so that I can just load the blocks I need, say something like projectdata: loadrecords/start/end project-datafile 120 135 Is there a way I can do this?

I will not include a self-destruct mechanism unless absolutely necessary. If it is necessary, it will not be a large red button labeled ``Danger: Do Not Push''. The big red button marked ``Do Not Push'' will instead trigger a spray of bullets on anyone stupid enough to disregard it. Similarly, the ON/OFF switch will not clearly be labeled as such.
