A comment on Cash App migrated 400TB of data to PlanetScale's cloud. Parent comment
> At peak times, Cash App's database handles approximately 3–4 million queries per second (QPS) across 400 shards, totaling around 400TiB of data.
400TiB represents not a lot of this data. If each query stored only 1 byte, this would only be 4 years worth of this data.
If duplicated, or processed and the results stored, that would add up, too.
