-------------------------------
Summary: ParquetWriter.Builder (and subclasses) instances are hard
to reuse
Key: PARQUET-1562
URL: https://issues.apache.org/jira/browse/PARQUET-1562
Project: Parquet
Issue Type: Improvement
Components: parquet-mr
Affects Versions: 1.10.1
Reporter: Victor
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.
