Hello, First off, please try to clean up formating of emails to be legible when forwarding/quoting previous messages multiple times, especially when most of the quotes do not contain any useful information. It makes it much easier to parse the message and thus quicker to answer.
The short answer is that we switched to 2.4 and more recently to 2.6 as the default to enable the usage of features these versions provide. As you have correctly quoted from the docs you can still write 1.0 if you want to ensure compatibility with systems that can not process the 'newer' versions yet (2.6 was released in 2018!). You can find the long form discussions about these changes here: https://issues.apache.org/jira/browse/ARROW-12203 https://lists.apache.org/thread/027g366yr3m03hwtpst6sr58b3trwhsm Best Jacob On 2024/04/24 02:32:01 Prem Sahoo wrote: > Hello Team, > Could you please share your thoughts about below questions? > Sent from my iPhone > > Begin forwarded message: > > > From: Prem Sahoo <prem.re...@gmail.com> > > Date: April 23, 2024 at 11:03:48 AM EDT > > To: dev-ow...@arrow.apache.org > > Subject: Re: PyArrow Using Parquet V2 > > > > dev@arrow.apache.org > > Sent from my iPhone > > > >>> On Apr 23, 2024, at 6:25 AM, Prem Sahoo <prem.re...@gmail.com> wrote: > >>> > >> Hello Team, > >> Could anyone please help me on below query? > >> Sent from my iPhone > >> > >>>> On Apr 22, 2024, at 10:01 PM, Prem Sahoo <prem.re...@gmail.com> wrote: > >>>> > >>> > >>> Sent from my iPhone > >>> > >>>>> On Apr 22, 2024, at 9:51 PM, Prem Sahoo <prem.re...@gmail.com> wrote: > >>>>> > >>>> > >>>> > >>>>> > >>>>> > >>>>> Hello Team, > >>>>> I have a question regarding Parquet V2 writing thro pyarrow . > >>>>> As per below Pyarrow started writing Parquet in V2 encoding. > >>>>> https://arrow.apache.org/docs/python/generated/pyarrow.parquet.write_table.html#pyarrow.parquet.write_table > >>>>> > >>>>> version{“1.0”, “2.4”, “2.6”}, default “2.6” > >>>>> Determine which Parquet logical types are available for use, whether > >>>>> the reduced set from the Parquet 1.x.x format or the expanded logical > >>>>> types added in later format versions.
