> There's no current standard convention, there's a few ways such could be sent though such as via a struct array with one row and fields for each of those or various other configurations. > > Passing such statistics would be beyond the scope of the current C Data interface IMHO I would argue that it makes sense to include statistical information in the C data interface. Efficient execution of complex queries requires statistical information, and I believe that most Arrow Producers possess this information. Therefore, it should be somehow passed. An alternative I can think of for the C-Data interface is to wrap the statistical information in top-level objects (e.g., ArrowRecordBatch in Python), but that approach is quite cumbersome and would necessitate specific implementations for every client API. -- This is an automated message from the Apache Git Service.
