Work Description: lgajowy commented on issue #5242: [BEAM-214] ParquetIO
URL: https://github.com/apache/beam/pull/5242#issuecomment-389227867
Ok, I posted some new commits. They include:
- writing slices of bytes
- cleanup of redundant code
- jenkins job for the IT (sorry, I somehow forgot to commit this earlier)
- applying other suggestions
As I mentioned in comments, some more investigation is needed regarding
reading. I can work on this in this PR or in some consequent one (which option
do you think is best?)
Besides writing slices of bytes, the writing part can also be further
optimized by adding the `blockSizeHint` and enabling block size support.
However, I didn't find any way to reach `Filesystem.getScheme()` in `open()`
method which would allow me to set `defaultBlockSize()` based on filesystem
type. Maybe you have any hints about this?
