It's possible to create an arrow::Array from multiple `arrow::Buffer` instances via `arrow::ArrayData`, and each `arrow::Buffer` can have its own memory manager, and device allocation type. the behavior of ` arrow::ArrayData::ViewOrCopyTo` depends on the behavior of MemoryManager fo `to `[parameter](https://github.com/apache/arrow/blob/cfff4d5b848ba551959d92c2631c582e8508241e/cpp/src/arrow/array/data.cc#L179-L182) in `arrow::ArrayData::ViewOrCopyTo` and MemoryManager and DeviceAllocationType type of a buffer according to below codes https://github.com/apache/arrow/blob/cfff4d5b848ba551959d92c2631c582e8508241e/cpp/src/arrow/device.cc#L103-L117 https://github.com/apache/arrow/blob/cfff4d5b848ba551959d92c2631c582e8508241e/cpp/src/arrow/device.cc#L221-L234. 1. Are there any practical examples where an `arrow::Array` contains buffers from different memory managers and device allocation type, or is this scenario purely theoretical? -- This is an automated message from the Apache Git Service.
