hi Nikola, Yes, we are still working on completing support for the date and time types in the stream and file formats.
ARROW-617 is the last item where we need to reconcile questions about the memory representation for time types, then we need to add integration tests to validate Java->C++/Python compatibility. ARROW-510 https://issues.apache.org/jira/browse/ARROW-510 is the JIRA for the integration tests. Java support is already in the works in ARROW-582, but it's blocked by ARROW-617 I'm sorry for the inconvenience -- I trust we can resolve this soon and have the 0.3 release out with full date/time type support within the next few weeks. If you have any opinions to share in the questions raised in the above JIRAs please feel free to share =) Thanks Wes On Wed, Mar 15, 2017 at 10:37 AM, Nikola Zezelj <[email protected]> wrote: > Hi, > > I have an Arrow table created in Java that I convert into bytes and push to > my Python client to read.
