> With a _very_ brief search, I wasn't able to find if datafusion regularly computes statistics for batches (are batches and micro partitions 1-1?) or if there is a default algorithm for various non-numeric data types. It does not compute statistics for RecordBatches It computes statistics at planning time for Partition (basically entire ExecutionPlans, possibly partitioned by value) -- This is an automated message from the Apache Git Service.
