vinothchandar opened a new pull request #2332:
URL: https://github.com/apache/hudi/pull/2332
- Changes the syncing model to only move over completed instants on data
timeline
- Syncing happens postCommit and on writeClient initialization
- Latest delta commit on the metadata table is sufficient as the watermark
for data timeline archival
- Cleaning/Compaction use a suffix to the last instant written to metadata
table, such that we keep the 1-1
- .. mapping between data and metadata timelines.
- Got rid of a lot of the complexity around checking for valid commits
during open of base/log files
- Tests now use local FS, to simulate more failure scenarios
- Some failure scenarios exposed HUDI-1434, which is needed for MOR to work
correctly
