    Description

      Data redundancy form – replication or erasure coding, should be orthogonal to block layout – contiguous or striped. This JIRA explores the combination of Erasure Coding + Contiguous block layout.

      As will be detailed in the design document, key benefits include preserving block locality, and easy conversion between hot and cold modes.
