[$250] DynamoDB Timeout #396
Description
@afrisalyp - We're seeing timeouts now in other operations (not just git access links). See below for a log when a user tried to archive a project.
What we're thinking is that:
- Maybe we should use
queryinstead ofscanOne? - Are the indices correct for how we are querying / scanning? I see we have an index on
tcDirectId, but do we need any other indices to speed things up?
From @rootelement :
i don’t believe this is correct:
https://github.com/topcoder-platform/topcoder-x-ui/blob/develop/src/common/db-helper.js#L85
all() ?
you’re trying to pull the whole table and filter it?
i know query is better than scan, but scan might need a better hash and range key based on the model you’re trying to pull from
