Project description

Welcome to DistKV!

DistKV is a master-less distributed key-value storage system. It circumvents the CAP theorem by assuming that keys are usually only changed by one node. It is resistant to partitioning and intended to be always-on; while it might delay – but will not lose – any updates.

DistKV does not support data partitioning. Every node stores the whole data set and can instantly deliver mostly-uptodate data.

DistKV does not have a disk-based storage backend; periodic snapshots and event logs are used to restore a system, if necessary.

API

DistKV offers an efficient msgpack-based interface to access data and to change settings. For compatibility, a front-end that mimics etcd2 is available.

Status

Some of the above is still wishful thinking.

DistKV has rich accessors and can distribute data, but not yet recover.
