[C++] Support for writing TIMESTAMP_NANOS Parquet metadata #20028
Comments
TP Boudreau / @tpboudreau: The enhancement I'm contemplating (and have largely completed) involves switching over to using (that is, generating on write, recognizing on read) the new parquet.thrift LogicalType (aka "annotation") metadata recently introduced into parquet-cpp (see PARQUET-1411). Thus the patch will be broader than just adding nanosecond units to timestamps, but will include that.

This was brought up on the mailing list.
We also will need to do corresponding work in the parquet-cpp library to opt in to writing nanosecond timestamps instead of casting to micro- or millisecond.
