> We propose to implement Erasure Coding in Apache Ozone to provide efficient
> storage. With EC in place, Ozone can provide same or better tolerance by
> giving 50% or more storage space savings.
> In HDFS project, we already have native codecs(ISAL) and Java codecs
> implemented, we can leverage the same or similar codec design.
> However, the critical part of EC data layout design is in-progress, we will
> post the design doc soon.
