Hello
I just learned arrow now provided a native reader/writer implementation on C++
to allow user directly read parquet file into Arrow Buffer and Write to parquet
file from arrow buffer.
I am wondering is there any plan on making the same support on the Java side?
I found an implementation

strangely enough I was unaware of the apache CoC which has been around for
a while.
How about we add a CODE_OF_CONDUCT.md at the root of the repo pointing to
the apache CoC?
It seems to be the place people would look at first.

So seems like there is no solution to implement such mechanism using the
low-level API? I tried to dump the arrow::Buffer after each rowgroup is
completed, but looks like it is not a clear cut, that pages starting from
the second rowgroup became unreadable (the schema is correct tho).
If this
In my experience and experiments it is really hard to approximate target sizes.
A single parquet file with a single row group could be 20% larger than a
parquet files with 20 row groups because if you have a lot of rows with a lot
of data variety you can lose dictionary encoding options. I

hi Hatem -- the arrow::FileWriter class doesn't provide any way for

Hi Arjit,
I'd also recommend you to have a look at Parquet website:
https://parquet.apache.org/
You can find a couple of old, but great presentations there, I recommend
you to watch those to understand the basics (despite Parquet improved
during the years with additional features, the basics
I think if I've understood the problem correctly, you could use the
parquet::arrow::FileWriter

The basic pattern is to use an object to manage the FileWriter lifetime, call
the WriteTable method for each row group,
Hi Arjit,
I'm new around here too but interested to hear what the others on this list
have to say. For C++ development, I've recommend reading through the examples:
