Piotr Findeisen commented on PARQUET-2088:
------------------------------------------
FWIW ORC just added "software version" field
[https://github.com/apache/orc/pull/904] / ORC-984 .
> Different created_by field values for application and library
> -------------------------------------------------------------

> Key: PARQUET-2088
> URL: https://issues.apache.org/jira/browse/PARQUET-2088
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-mr
> Affects Versions: format-2.9.0
> Reporter: Joshua Howard
> Priority: Minor
>
> There seems to be a discrepancy in the Parquet format created_by field
> regarding how it should be filled out. The parquet-mr library uses this value
> to enable/disable features based on the parquet-mr version
> [here|https://github.com/apache/parquet-mr/blob/5f403501e9de05b6aa48f028191b4e78bb97fb12/parquet-column/src/main/java/org/apache/parquet/CorruptDeltaByteArrays.java#L64-L68].
> Meanwhile, users are encouraged to make use of the application version
> [here|https://www.javadoc.io/doc/org.apache.parquet/parquet-format/latest/org/apache/parquet/format/FileMetaData.html].
> It seems like there are multiple fields needed for an application and
> library version.
