Details

    Description

      Write the column indexes described in PARQUET-922.
      This is the first phase of implementing the whole feature. The implementation is done in the following steps:

      • Utility to read/write indexes in parquet-format
      • Writing indexes in the parquet file
      • Extend parquet-tools and parquet-cli to show the indexes
      • Limit index size based on parquet properties
      • Trim min/max values where possible based on parquet properties
      • Filtering based on column indexes

      The work is done on the feature branch column-indexes. This JIRA will be resolved after the branch has been merged to master.
