The majority of code stats (the data being stored) is received for the current day. Older data still comes in, but in that case we just update the SSDB cache after writing the new data to S3. The reason we don't use SSDB as the main source of truth is because S3 provides replication and resilience.

  Sure, I meant a mirror is just a cache for data that doesn't change. I edited the original comment, because it doesn't help explain why we used SSDB here.
