DDSketch: a fast and fully-mergeable quantile sketch with relative-error guarantees Masson et al., VLDB’19. Datadog handles a ton of metrics – some customers have endpoints generating over 10M points per second! For response times (latencies) reporting a simple metric such as ‘average’ is next to useless. Instead we want to understand what’s happening at different latency percentiles (e.g p99).

I briefly mentioned that batch mode data is normalized in my last article Batch Mode Bitmaps in SQL Server. All data in a batch is represented by an eight-byte value in this particular normalized format, regardless of the underlying data type.
