We've made a lot of progress recently on hammering out some small details in the Arrow metadata.
The data types where we need to complete the implementation, JSON read/write test for integration testing, and integration tests themselves, are: - Date (32- and 64-bit variants) - Time, for all units - Timestamp, for all units, + timezone metadata - Fixed width binary - Dictionary Given the progress that's happened since the 0.2 release (102 JIRAs resolved so far), I propose that we prioritize the date and time type integration tests (see ARROW-510 and attached blockers) and then push immediately to release 0.3 as soon as possible. On the C++ side, we completed the binary/IPC read/writes for date and time types, and I should be able to add the JSON support for testing in the next few days. ARROW-670 is the JIRA for the 0.3 release, please attach blockers and perhaps we can get out a release candidate within the next 2 weeks. Thanks! Wes
