[jira] [Created] (ARROW-12500) [C++][Dataset] Consolidate similar tests for file formats
David Li created ARROW-12500: Summary: [C++][Dataset] Consolidate similar tests for file formats Key: ARROW-12500 URL: https://issues.apache.org/jira/browse/ARROW-12500 Project: Apache Arrow Issue Type: Improvement Components: C++ Reporter: David Li Assignee: David Li Fix For: 5.0.0 Between CSV/Parquet/IPC we have a number of very similar or in some cases essentially identical tests. As we're doing more refactoring and development it would be nice to consolidate these tests so that we can ensure all formats behave consistently and get the same level of testing. For instance, ARROW-11772 now adds more comprehensive tests for scanning IPC which don't yet apply to Parquet/CSV. This sort of consolidation may also be nice to do in Python. -- This message was sent by Atlassian Jira (v8.3.4#803005)

[jira] [Created] (ARROW-12497) [C++] Implement array expression from R in C++
Nic Crane created ARROW-12497: - Summary: [C++] Implement array expression from R in C++ Key: ARROW-12497 URL: https://issues.apache.org/jira/browse/ARROW-12497 Project: Apache Arrow Issue Type: New Feature Components: C++ Reporter: Nic Crane As discussed here: https://github.com/apache/arrow/pull/10056#discussion_r616985185 Currently, the R implementation allows for array expressions to be built which are later evaluated within a single call to Filter rather than in multiple operations. This functionality should be moved to the C++ level so it's dealt with at a lower level. -- This message was sent by Atlassian Jira (v8.3.4#803005)

Summary: [Python] Add an helper method to decode a DictionaryArray
back to a plain Array
Key: ARROW-12492
URL: https://issues.apache.org/jira/browse/ARROW-12492
Project: Apache Arrow
Issue Type: New Feature
Components: Python
Reporter: Alessandro Molina
To create a DictionaryArray pyarrow currently offers the
{{Array.dictionary_encode}} helper, but there is a lack of an obvious way to do
the reverse. A {{DictionaryArray.decode}} helper could provide an immediate
obvious solution to get back an unrolled Array from the dictionary encoded
version.
