horizontal partitioning (by key range)

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

by using Terracotta Server

none

Sharding, horizontal partitioning

Multi-source replication using RAFT

yes

by using Terracotta Server

none

Multi-source replication
Source-replica replication

Offers an API for user-defined Map/Reduce methods

can be realized in PL/SQL

Immediate Consistency

Tunable Consistency (Strong, Eventual, Weak)

none

Immediate Consistency

Support to ensure data integrity after non-atomic manipulations of data

ACID

yes

supports JTA and can work as an XA resource

ACID

isolation level can be parameterized

Support for concurrent manipulation of data

yes

Durability

Support for making data persistent

yes

using a tiered cache-storage approach

yes

In-memory capabilities

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

yes

Version 12c introduced the new option 'Oracle Database In-Memory'
