--------------------------------------
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.
