database - how to improve time for select in kdb -
i have created trade database on local machine, partitioned date.
select trade date=x takes 100 ms, when select trade date=x,sym=`alpha, takes ~1-3 seconds.
is there trick i'm missing (using `g#sym gives error 'par).
you can use dbmaint.q apply attributes to partitioned tables. see here . specifially @ setattrcol function. adding attribute speed query significantly. suggest using p# on id column if possible. should faster look-ups more difficult maintain.
