Keyspace. Yet Another Key-Value Store—this one focuses on high availability, with one server in the cluster serving as master (and handling all writes), and the paxos algorithm handling replication and ensuring a new master can be elected should the existing master become unavailable. Clients can chose to make dirty reads against replicated servers or clean reads by talking directly to the master. Underlying storage is BerkeleyDB, and the authors claim 100,000 writes/second.

Historically the project policy has been to avoid putting replication into core PostgreSQL, so as to leave room for development of competing solutions [...] However, it is becoming clear that this policy is hindering acceptance of PostgreSQL to too great an extent, compared to the benefit it offers to the add-on replication projects. Users who might consider PostgreSQL are choosing other database systems because our existing replication options are too complex to install and use for simple cases.
