Wes McKinney resolved PARQUET-1022.
-----------------------------------
Resolution: Won't Fix
Assignee: Wes McKinney
I'm closing as Won't Fix. Trying to modify existing files (overwriting the
existing file footer) is a pretty big can of worms, and would add a bunch of
complication to the codebase to initialize various classes with a partially
written file
> [C++] Append mode in parquet-cpp
> --------------------------------
>
> Key: PARQUET-1022
> URL: https://issues.apache.org/jira/browse/PARQUET-1022
> Project: Parquet
> Issue Type: New Feature
> Components: parquet-cpp
> Affects Versions: cpp-1.1.0
> Reporter: yugu
> Assignee: Wes McKinney
> Priority: Major
>
> As said, currently trying to work out a append feature for parquet files in
> c++.
> (been searching through repo etc, can't find example tho..)
> Current solution is to (assume no schema changes that is):
> Read in metadata
> Change metadata based on appended rows+ original rows
> Append a new row group (or multiple row group writer)
> Write the new rows.
> ---
> The problem is that, is approached this way, the original last row group may
> not be complete filled. Was wondering if there is a fix or I'm using the api
> wrong...
> Thanks ! : D
