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 | Consistency Model | Transactions | C Client | Notes |
---|---|---|---|---|
ctdb | Volatile DBs: Basically Sequential Consistency Persistent DBs: Strict Serializability |
No Yes |
yes | |
etcd | Linearizability | LWT ("mini") | yes | |
Ceph Rados | Linearizability | LWT via Object Operations | yes | |
YugabyteDB | Linearizability with LWT | yes | yes | |
Apache Cassandra | Configurable: Linearizability with LWT New: Strict Serializability [1] |
yes | yes | |
FoundationDB | Strict Serializability | yes | yes | |
CockroachDB | Serializable+, Strong Partition Serializability | LWT | yes | 1 |
ScyllaDB | Single-key Linearizability with LWT | LWT | yes | |
tikv | 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

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