    Key new features

      • Recommend optimized defaults for segment by and order by when configuring compression through analysis of table configuration and statistics.
      • Add planner support to check more kinds of WHERE conditions before decompression.
        This reduces the number of rows that have to be decompressed.
      • You can now use minmax sparse indexes when you compress columns with btree indexes.
      • Vectorize filters in the WHERE clause that contain text equality operators and LIKE expressions.
