You can use [Table.slice](https://arrow.apache.org/docs/python/generated/pyarrow.Table.html#pyarrow.Table.slice) if you don't care about the extra memory usage. Slice is zero-copy: it only mark the offset of the buffers, so it's fast, but the poped rows still exist in memory. If you do care about memory usage, `take` is the best option AFAIU, because it is optimized to merely a bunch of `memcpy`s when you are taking contiguous indices. -- This is an automated message from the Apache Git Service.
