List of scalable Key/Value Stores
For an overview of Consistency Models see Jepsen or Wikipedia. Note: LWT are defined as multiple operations on a single key.
Name | Type | Consistency Model | Transactions | C Client | Notes |
---|---|---|---|---|---|
ctdb | K/V | Volatile DBs: Basically Sequential Consistency Persistent DBs: Strict Serializability |
No Yes |
yes | |
etcd | K/V | Linearizability | LWT ("mini") | yes | |
Ceph Rados | K/V | Linearizability | LWT via Object Operations | yes | |
YugabyteDB | SQL | Single-key Linearizability with LWT | yes | yes | |
Apache Cassandra 1-4 | CQL | Configurable, highest: Single-key Linearizability with LWT |
yes | yes | |
Apache Cassandra 5 | CQL | Upcoming: Strict Serializability [1] |
yes | yes | |
FoundationDB | K/V | Strict Serializability | yes | yes | |
CockroachDB | SQL | Serializable+, Strong Partition Serializability | LWT | yes | 1 |
ScyllaDB | CQL | Single-key Linearizability with LWT | LWT | yes | |
tikv | K/V | Strong Consistency[2] | yes (Percolator based) | no (C++) | |
Apache Pegasus | ? | ? | ? | no (C++) | |
Apache HBase | ? | ? | ? | ? | |
Apache Ignite | ? | ? | ? | ? |
Rapid Samba dbwrap backend prototyping
A new dbwrap backend called dbwrap_py that calls into Python for the database operations. Available backends:
List of Opensource Clustered Filesystems
Name | Built on-top of Object Storage | Notes |

Ceph | yes | |
GlusterFS | no | |
JuiceFS | yes | |
MooseFS | no | |
ObjectiveFS | yes | |
Lustre | no | |
BeegFS | no |
