---------------------------------
Summary: [C++] Support dictionary memos when reading/writing
record batches using cuda IPC
Key: ARROW-8927
URL: https://issues.apache.org/jira/browse/ARROW-8927
Project: Apache Arrow
Issue Type: Improvement
Reporter: Alex Baden
Currently, the cuda IPC calls for `ReadRecordBatch` do not accept a dictionary
memo as a parameter, building an empty memo before calling
`ipc::ReadRecordBatch`. As such, adding a test which duplicates
`TestCudaArrowIpc, BasicWriteRead` but calls `MakeDictionary` to create the
record batch fails because the dictionaries for the original record batch are
not found. The cuda IPC calls should be modified to take a dictionary memo,
just like the standard IPC API.
