Pull request overview
This PR introduces an optional, user-supplied timestamp parsing format that’s threaded from Connection config through result fetching and into the non-Arrow conversion paths, with unit tests covering the new behavior.
Changes:
- Added
parse_timestamp()helper and plumbed an optionaltimestamp_formatthrough Thrift column-based result conversion. - Added
non_arrow_timestamp_formatconnection option and passed it into both Thrift and SEA non-Arrow timestamp conversions. - Added unit tests for explicit-format parsing and fallback to
dateutilparsing.
