Wes McKinney updated PARQUET-749:
---------------------------------
Summary: [C++] Schema building ParquetFileWriter (was: Schema building
ParquetFileWriter)
> [C++] Schema building ParquetFileWriter
> ---------------------------------------
>
> Key: PARQUET-749
> URL: https://issues.apache.org/jira/browse/PARQUET-749
> Project: Parquet
> Issue Type: New Feature
> Components: parquet-cpp
> Reporter: Uwe L. Korn
> Assignee: Uwe L. Korn
> Priority: Major
>
> Sometimes you want to write a Parquet file column-by-column without knowing
> the whole schema upfront. Format-wise this should be possible if you only
> have a single RowGroup. The user would write column after column and only at
> the end (when we need to write the metadata), the whole schema can be
> assembled.
> Currently ParquetFileWriter only supports writing files when the schema is
> known upfront.
> Limitations for the start:
> * A single RowGroup is written
> * No nestings
