all tables are translated to an ordered KV store and then broken down into 64MB ranges, which are then used as replicas in RAFT

Sharding

depending on storage layer

Sharding, horizontal partitioning

Methods for redundantly storing data on multiple nodes

yes

managed transparently by AWS

Multi-source replication using RAFT

Configurable replication on table/partition-level

depending on storage layer

Multi-source replication
Source-replica replication

Offers an API for user-defined Map/Reduce methods

yes

can be realized in PL/SQL

yes

Durability

Support for making data persistent

yes

In-memory capabilities

Is there an option to define some or all structures to be held in-memory only.

depending on storage layer

yes
