Neville Dipale commented on ARROW-11183:
----------------------------------------
Hey [~aldanor], I had look at the commit. The nanosecond type is part of the
2.6 format, which we don't fully support yet.
There's 3 tasks,
# Wire up the 2.6 changes in the parquet-format, it's clear that we're missing
an enum (there might be more that's missing)
# Add a reader for ts-nano
# Add a writer for ts-nano, that uses the old int96 writer if the legacy
support is requested, or uses the new ts-nano for non-legacy types
Would you like to contribute some of the above? I can help out with 1 as a
start.
Thanks
