Hi,
I guess I am a 'small cheese' with only 2m rows in my authentication table? I am using PgSQL and have btree'd my timestamp columns, but it still takes only 3.6s to pull 10k rows worth of just todays data.
ah..you have the immediate advantage of postgreSQL
I thought the point of index'ing your columns (sensibly) meant that the size of the table was not meant to really be too much of a killer?
aye - but you also need a DB system that doesnt lock everything just because you looked at it (quick, take a peek while its not looking! ;)) it didnt take too long for me to suffer with MySQL as supplied so often by default - then i researched and moved to eg InnoDB engine...then I learnt about choosing indexes carefully - and how too many can kill you too. ...that came alongside the 'explain' command. then i moved to postgres - with that powering the system theres far less to wory about (espcially later versions that dont need a monthly VACUUM 8-) alan
