* Use the whole frame when writing rows. This patch makes the following adjustments to enable writing larger single rows to frames: 1) RowBasedFrameWriter: Max out allocation size on the final doubling. i.e., if the final allocation "naturally" would be 1 MiB but the max frame size is 900 KiB, use 900 KiB rather than failing the 1 MiB allocation. 2) AppendableMemory: In reserveAdditional, release the last block if it is empty. This eliminates waste when a frame writer uses a successive-doubling approach to find the right allocation size. 3) ArenaMemoryAllocator: Reclaim memory from the last allocation when the last allocation is closed. Prior to these changes, a single row could be much smaller than the frame size and still fail to be added to the frame. * Style. * Fix test. |
