prashantwason opened a new pull request #5179:
URL: https://github.com/apache/hudi/pull/5179
## What is the purpose of the pull request
Partition metadata files are stored in each partition to help identify the
base path of a table. These files are saved in the properties file format. Some
query engines do not work when non Parquet/ORC files are found in a partition.
Added a new table config 'hoodie.partition.metafile.use.data.format' which
when enabled (default false for backward compatibility) ensures that partition
metafiles will be saved in the same format as the base files of a dataset.
For new datasets, the config can be set via hudi-cli. Deltastreamer has a
new parameter --partition-metafile-use-data-format which will create a table
with this setting.
## Brief change log
1. New table config 'hoodie.partition.metafile.use.data.format
2. New argument for HoodieDeltaStreamer --partition-metafile-use-data-format
3. Unit tests for table path utils
4. Unit test for copy on write table
