Instrumentation¶

REL provides hooks that can be used to log or instrument your queries.

repo.Instrumentation(func(ctx context.Context, op string, message string, args ...any) func(err error) {
    t := time.Now()

    return func(err error) {
        duration := time.Since(t)
        log.Print("[duration: ", duration, " op: ", op, "] ", message, " - ", err)
    }
})
