go-ipfs-chunker implements data Splitters for go-ipfs.
👉 We highly recommend switching to the maintained version at https://github.com/ipfs/boxo/tree/main/chunker. 🏎️ Good news! There is tooling and documentation to expedite a switch in your repo.

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.
go-ipfs-chunker works like a regular Go module:
> go get github.com/ipfs/go-ipfs-chunker
import "github.com/ipfs/go-ipfs-chunker"
