> go-ipfs-chunker provides the Splitter interface. IPFS splitters read data from a reader an create "chunks". These chunks are used to build the ipfs DAGs (Merkle Tree) and are the base unit to obtain the sums that ipfs uses to address content.
> The package provides a SizeSplitter which creates chunks of equal size and it is used by default in most cases, and a rabin fingerprint chunker. This chunker will attempt to split data in a way that the resulting blocks are the same when the data has repetitive patterns, thus optimizing the resulting DAGs.
I think they should use the rolling hash based chunking by default
