Snippets

Spread retries out so a recovering service isn't stampeded.

Skip events that were already processed, inside one transaction.

Make the compiler tell you when a union gains a case.

Top queries by total time (needs pg_stat_statements).

Never let a balance underflow.

Wrap a parent context with a deadline.

Retry a flaky call a fixed number of times.

Rolling restart and watch until it's healthy.

Debounce a fast-changing value, e.g. a search box.

Click and wait for the matching API response instead of sleeping.
