[jira] [Created] (PARQUET-1022) Append mode in parquet-cpp

yugu created PARQUET-1022:
-----------------------------

             Summary: 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


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
