Hi all, I would like to start a vote for to adopt parquet-format PR 601 [1]. This PR allows the TimestampType logical type annotation to annotate FIXED_LEN_BYTE_ARRAY(12) columns in order to support the full SQL timestamp range in nanoseconds. All three time units (millis/micros/nanos) are supported for such columns. There are Java [2] and C++ [3] reference implementations (the C++ one includes Parquet to Arrow type conversion as well), as well as a parquet-testing PR [4] to add a file with such columns.
Please vote in the next 72 hours. [ ] +1 Approve the proposed format change [ ] +0 No opinion [ ] -1 Do not approve (please provide specific reasons) Cheers, Div [1] https://github.com/apache/parquet-format/pull/601 [2] https://github.com/apache/parquet-java/pull/3680 [3] https://github.com/apache/arrow/pull/50916 [4] https://github.com/apache/parquet-testing/pull/123
