> Remove two layers of buffers (the 16KB one and 2KB one) and replace with a single buffer called decompressionBuffer. The time it takes to prepare a batch for decompression will be bounded by the allocation of largest buffer and hence, using only one large buffer (16KB) doesn’t cause any regression.
