Distributed File Systems

Why are distributed file systems hard?

Distributed systems need performance

• Performance fixedBy Sharding

• Sharding fixedBy Faults

• Faults fixedBy Tolerance

• Tolerance fixedBy Replication

• Replication fixedBy Inconsistencies

• Inconsistencies fixedBy Low performance

• Low performance fixedBy mitigate with Probabilistic Bounded Staleness
