I just remembered a bigger issue I ran into. I wanted to read from IPC but I don’t have a file. I do have the data as [u8] already. The current API incurs more copies than necessary (I think) and therefore the performance of reading IPC is worse than in JS. ( https://issues.apache.org/jira/projects/ARROW/issues/ARROW-11696).
