Partitioning methods

Methods for storing different data on different nodes

Sharding

Sharding, partitioned with virtual buckets by user defined affinity key. Live resharding for scale up and scale down without maintenance downtime.

Sharding

based on HBase

yes

Optimistic locking

No - written data is immutable

yes, cooperative multitasking

yes

Durability
