self host getting stuck

Hello i am self hosting convex using docker. it was working perfectly for months. then suddenly one day after restarting my pc (windows 11) running the backend no longer works. the commands:

$env:PATH += ";C:\Program Files\Git\bin"
$env:AWS_LC_SYS_PREBUILT_NASM = "1"
just run-local-backend

$env:PATH += ";C:\Program Files\Git\bin"
$env:AWS_LC_SYS_PREBUILT_NASM = "1"
just run-local-backend

the log

cargo run -p local_backend --bin convex-local-backend -- "$@"

keeping in mind i did not change the schema or anything related to the database for over a week now and it was running perfectly i desperately need help as we are developing a project for work well it works it just takes 30 minutes to load..

Is that the entire log? It looks like the process is still running from this Ah, hm, that makes more sense. How big's your DB, and have you turned on rust tracing?

hi sorry for responding late my database is pretty big i think i have 24 tables and about 80 indexes it only started taking this long after i tested my app and used it for a whole day and filled it with alot of data so i think its the indexes that take long?

ari-cake•2mo ago

Not sure - what do the logs say? And let’s ignore number of tables, how many documents / rows? How much data (in gigabytes)
