By using transaction functions

yes

yes, before/after data modification events, on replication events, client session events

Partitioning methods

Methods for storing different data on different nodes

Sharding

none

But extensive use of caching in the application peers

none

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

Methods for redundantly storing data on multiple nodes

selectable replication factor

none

But extensive use of caching in the application peers

With clustering: 2 database servers on different computers operate on identical copies of a database
