>  * 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}}.
