Support for TIMESTAMP_NANOS

[romankarlstetter]

Hi!

In parquet-format, there is now support for TIMESTAMP_NANOS: apache/parquet-format#102

For parquet-cpp, this is not yet supported. I have a few questions now:

• is there an overview of what release of parquet-format is currently fully support in parquet-cpp (something like a feature support matrix)?
• how fast are new features in parquet-format adopted?

I think having a document describing the current completeness of implementation of the spec would be very helpful for users of the parquet-cpp library.

Thanks,
Roman

Can you please start a mailing list discussion about this? Thanks

I can confirm TIMESTAMP_NANOS does not currently work at all with the nasty side effect of incomplete/corrupt parquet file if one tries to use it... 👎

Just for reference, this is the discussion on the mailing list:

Looks like someone needs to open a JIRA issue
