Analytics dashboard: queries crawl as the data grows
Stuck point
it was instant at a thousand rows and now crawls at a hundred thousand. one chart takes 6 seconds. I know I need indexes but I dont know how to find the slow query.
progress status — how done is it, really?
that 18-pt gap is probably exactly where the last step is hiding.
What I need help with
how to find + fix the slow queries so it loads fast again.
Your first move
Run EXPLAIN ANALYZE on the slow query, find the sequential scan, and add an index on the column it filters or sorts by.
the road everyone walks
every shipped app walked this exact road. being stuck partway isn't failing, it's the middle of the climb — and the AI read (66%) puts this project roughly here.
next stop: real people use it · they find it and come back.
want YOUR whole road plotted. every step, tool & why? plan your buildknow the missing piece? drop it in the room below.
