Summary
Use Erasure Coding algorithm for efficient storage
Abstract
Support Erasure Coding for read and write pipeline of Ozone.
Status
The design doc describes two main methods to implement EC:
- Container level, async Erasure Coding, to encode closed containers in the background
- Block level, striped Erasure Coding
Second option can work only with new, dedicated write-path. Details of possible implementation will be included in the next version.
