----------------------------------------------
Summary: [C++] Switch to format version 2 as default for writing
Parquet
Key: PARQUET-1972
URL: https://issues.apache.org/jira/browse/PARQUET-1972
Project: Parquet
Issue Type: Improvement
Components: parquet-cpp
Reporter: Joris Van den Bossche
Related to the thread on the arrow dev mailing list:
https://lists.apache.org/thread.html/rf1a377c66990ae5ac0693119d416c93a7e19228d3eaaea8bd90acb17%40%3Cdev.arrow.apache.org%3E
Currently, when writing parquet files with Arrow (parquet-cpp), we default to
parquet format "1.0". In practice, this means that we don't use certain
LogicalTypes (eg we don't write integers other than int32/int64, and we don't
write the nanosecond timestamps).
I think it would be nice to enable nanosecond timestamps by default, but I also
have no idea how widely this is already supported by other readers.
To be clear, this is *not* about enabling _data page_ version 2 by default, in
Arrow that is governed by a separate option.
While checking this, I made an overview of which types were introduced in
which parquet format version, in case someone wants to see the details ->
