Daniel Parubotchy created ARROW-6870:
----------------------------------------
Summary: Add Support for Dictionary Arrays and Dictionary Encoding
Key: ARROW-6870
URL: https://issues.apache.org/jira/browse/ARROW-6870
Project: Apache Arrow
Issue Type: New Feature
Components: C#
Reporter: Daniel Parubotchy
The C# implementaiton of Arrow doesn't support dictionary arrays,
serialization/deserialization of dictionary batches, or dictionary encoding.
Dictionary arrays and dictionary encoding could provide a huge performance
benefit for certain data sets.
I propose creating dictionary array types that correspond to the existing array
types
