Research direction
Start by mapping the query-engine entry points for joins, MySQL mathematical functions, integral and variance functions, Csum, Count(distinct), event windows, tag filtering, and Interp queries. Done means the listed query capabilities are supported and the requested performance improvements are validated, but the issue names no files or tests.
