Isaac Nygaard created PARQUET-2490:
--------------------------------------
Summary: Add usage documentation for the Java library
Key: PARQUET-2490
URL: https://issues.apache.org/jira/browse/PARQUET-2490
Project: Parquet
Issue Type: Wish
Components: parquet-mr
Reporter: Isaac Nygaard
The Java parquet library has no usage documentation besides the sparse
information available in the README. The only thing I could find were a few old
(10yr) 3rd party tutorials scattered on the internet using the hadoop module. I
spent a work day sifting through the API docs and searching on the internet to
try to piece together something. Ultimately, I decided to give up on doing
Parquet files using Java because there are alternative file formats that are
better documented, and I felt trying to use parquet-mr would be a huge hassle
to maintain in the future. This library seems reasonably maintained and
comprehensive, but there is just a huge barrier to using the library which I
think turns off a lot of developers like me.
I kindly request usage documentation be written to cover all the major aspects
of the library, and for the more nitty gritty use cases, pointers to what API
classes/methods could be looked at further.
I may be misunderstanding the purpose of this library, and if so, is there a
different Java Parquet library that is recommended for higher level parquet
file IO?
