> what about performance with primitive types (e.g. int32) This PR builds on #1054 which yields a 2-6x speed up when using PrimitiveArrayReader on non-nested columns compared to current master. This is purely through better null handling, which this PR also benefits from. I do have some reservations about drawing too much from these benchmarks, I have found them to have strange interactions with my system's memory allocator, but its certainly not slower and is likely significantly faster. > compared to old array reader implementation That's the key thing about #1041 it doesn't replace this array reader implementation, it just adds the ability to extend it. For primitive types the performance of #1041 is therefore [unchanged](https://github.com/apache/arrow-rs/pull/1041#issuecomment-993816497), it just gives the ability to add optimisations such as #1054 -- This is an automated message from the Apache Git Service.
