A pure Go library implementing Reed-Solomon erasure coding with high performance (over 1GB/s per CPU core), including a Leopard implementation for high shard counts. It is a port of Backblaze's JavaReedSolomon library with additional optimizations.

Use cases

• add erasure coding redundancy to distributed storage
• recover lost data shards in Go
• implement parity encoding for files
• build fault-tolerant object storage
• encode data with more than 256 shards
• split data into data and parity shards

When to choose

• you need fast, pure-Go Reed-Solomon encoding/decoding without cgo
• you are building storage systems that must tolerate shard loss
• you need very high shard counts via Leopard coding

When to avoid

• you need forward error correction for network streams rather than block data
• you want a non-Go language binding
• you need simple replication instead of erasure coding
