Zoltan Ivanfi commented on PARQUET-1201:
----------------------------------------

[~rdblue] That is the branch indeed. Our idea with the feature branch was that 
each commit to the feature branch will happen via a PR and will go through the 
regular thorough reviewing process. We wanted to avoid opening a giant PR at 
the end which would be very hard to review anyway due to its sheer size. The 
community accepted this approach on the Parquet sync where we discussed it. 
Could you please review the individual PR-s instead? Thanks!

> 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}}.
