Re: language independent representation of filter expressions

2020-07-22 Thread Patrick Pai
Hi all, After some discussion with Steve, we'd like to propose and get feedback on an alternative to representing expressions entirely with flatbuffers. To give some context, we thought about how we'd construct flatbuffer expressions in Java or another language if we went down that route. We

Re: [RUST] Zero-copy Vec -> PrimitiveArray

2020-07-22 Thread vertexclique vertexclique
Hi; If you have odd sized Vec it is not possible to get a zero-copy array with Arrow. Since you will access to non allocated memory region if you try to get a zero-copy view on that. What you will receive at the end of your buffer will be some garbage bytes (not mentioning UB and ownership of the

[RUST] Zero-copy Vec -> PrimitiveArray

2020-07-22 Thread Ritchie Vink
Hey all, Is it possible in any way to go from a Rust Vec to an Arrow buffer. I know the alignments of arrow memory is 8 or 64 bits and this isn't the case for Rust's Vec type. Could we instantiate a Vec in any way such that a zero copy PrimitiveArray is possible? Thanks in advance, Ritchie Vink
