Description

Currently, 3fs defaults to a replication factor of 3. I would like to know if it supports other replication factors and if there are plans to support erasure coding (EC) in the future.

Questions

Custom Replication Factors: Does 3fs support replication factors other than the default of 3? If so, how can these be configured?
Erasure Coding: Are there any plans to implement erasure coding in 3fs? If yes, what is the expected timeline for this feature?

Additional Context

Understanding the flexibility in replication factors and the potential for erasure coding would help in planning storage strategies and optimizing resource usage.

Have the same question like will 3fs support RS at least later? Very interesting fs.
