Uwe L. Korn created PARQUET-749: ----------------------------------- Summary: 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
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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
