Description
Hi,
The builders to create ParquetWriter and AvroParquetWriter are very useful, but unfortunately their instance are very hard to reuse when you want to build multiple instance of ParquetWriter for different files but similar settings.
This is a shame because that's one of the concern solved by the builder pattern: from one builder you can build multiple things with similar parameters.
It would be useful if either:
- it was possible to create a builder from a pre-existing builder (except for the file name)
- it was possible to change the file name specified in the builder (and not have it definable only via constructor of the builder).
This would allow people to pass a set of options in the form of a builder to an object responsible of generically instantiating a PaquetWriter for multiple files for example.
