[jira] [Commented] (ARROW-11183) [Rust] [Parquet] LogicalType::TIMESTAMP_NANOS missing

Neville Dipale commented on ARROW-11183:
----------------------------------------

This is part of the Parquet format specification. Which version of parquet-format includes TIMESTAMP_NANOS?

> There's UnitTime::NANOS in parquet-format, but no nanosecond timestamp support (seemingly) in schema's LogicalType. What is needed to add support for nanosecond timestamps in Rust Parquet?
