> > A better implementation would be to keep the original buffer but slice it in multiple view buffers. This is exactly what the comment suggests: > > I understand that StringView types can utilize multiple data buffers. However, is it problematic to have multiple buffers that don’t own their memory? Specifically, is there an assumption that every buffer in an array must own the data it points to? I gather you’re suggesting that one buffer could own the data while others merely reference it. Slicing a buffer produces a buffer that owns its memory. See the `SliceBuffer` function implementation. > Actually, this compute function is not scalar. From what I observe in Arrow, the `unique` compute function is classified as a vector function. Ah, right. Then perhaps `vector_string.cc`? -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
