KnightChess opened a new pull request, #12270:
URL: https://github.com/apache/hudi/pull/12270
### Change Logs
After spark3.3 support TimeTravel SQL and Logical Plan, remove the
implementation in hudi, remain `index` DML SQL
### Impact
in spark, TIMESTAMP dataType is `TimestampType`, VERSION is `String`. And
the hoodie instance time format is not legal for spark to parse.
And from the perspective of usage, the concept of HUDI's timestamp concept
is more suitable for using VERSION, so in this pr:
- VERSION AS OF
- support digit string, contain hudi base timeline format -
[yyyyMMddhhmmssSSS], will return less or equal snapshots
- TIMSTAMP AS OF
- spark provides a rich date expression, will return less or equal
snapshots
### Risk level (write none, low medium or high below)
low
### Documentation Update
spark Time Travel Query tutorial, update
