Keyspace 1.1 Release

by Marton Trencseni on 2009/09/09

We are releasing version 1.1 of Keyspace, our consistently replicated key-value store, a major improvement over 1.0.x.

1. New PaxosLease algorithm does not require clock synchronization.
2. Added COUNT and DIRTYCOUNT commands.
3. Added /html/ part to HTTP interface, which pretty prints the list output.
4. Added possibility to reverse list direction.
5. The http://server:port/ welcome page prints the version number and master information.
6. Added database.numReaders config option.

The most important is: Keyspace no longer requires clock synchrony! This should make Keyspace as a distributed database much more attractive to new users. The new PaxosLease algorithm is described in the PaxosLease whitepaper.
