[jira] [Created] (ARROW-11696) [Rust] Create record batches from in memory IPC

Dominik Moritz created ARROW-11696:
--------------------------------------

             Summary: [Rust] Create record batches from in memory IPC
                 Key: ARROW-11696
                 URL: https://issues.apache.org/jira/browse/ARROW-11696
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust
            Reporter: Dominik Moritz


I have the IPC format of Arrow record batches in memory (e.g. as `&[u8]`) and would like to create a vector of batches while avoiding as many memory copies as possible. It would be great if there was a way to create the vector without having to go through the file abstraction. 

I might be misunderstanding the way the file reader works and maybe it does not incur memory copies. I think it does, though, since creating arrow record batches from a larger arrow buffer takes much longer.
