> I issued some comments (will still go through a second round of review) > > One side question, this design is different from the one of Postgres https://www.postgresql.org/docs/current/view-pg-stats.html > > that uses histograms. Is using histograms more suitable for OLTP workloads than OLAP/ I really don't know much, but I was curious about this choice What I see is those PG stats are table and column statistics for the user level. What we're building here is a foundational statistics infrastructure that serves as a basis for other statistical concepts. It is designed to satisfy various computational requirements and parameters (and they are extensible). It is built to be robust and error-prone. If you prefer displaying the stats as histograms, you can easily convert these new distributions into histograms using a few converter functions. -- This is an automated message from the Apache Git Service.
