> In our product we are using such custom allocators to track the memory usage of individual queries. I'd like to add a similarly named feature to arrow-rs which would generalize the Buffer::from_vec and MutableBuffer::from_vec functions. As @tustvold , @waynexia and I are discovering on https://github.com/apache/arrow-rs/pull/6336, adding the APIs to Buffer and MutableBuffer is just the start -- to really achieve the usecase I think we would need to preserve the allocation information through all the various kernels / transformations that arrow-rs provides. Also, @haohuaijin offers another potential usecase for this feature that is "accurately track total memory used by multiple arrow arrays that may share the same underlying Buffers (e.g. that were sliced, etc) in https://github.com/apache/arrow-rs/issues/6439 -- This is an automated message from the Apache Git Service.
