COMPUTE STATS on non-primitive columns

    XMLWordPrintableJSON

Details

    Description

      Currently Impala does not compute the stats for complex-type columns, as per the docs:

      Currently, the statistics created by the COMPUTE STATS statement do not include information about complex type columns. The column stats metrics for complex columns are always shown as -1. For queries involving complex type columns, Impala uses heuristics to estimate the data distribution within such columns.
