PostgreSQL 8.5 alpha 2 is out. “P.S. If you’re wondering about Hot Standby and Synchronous Replication, they’re still under heavy development and still (at this point) expected to be in 8.5.”—Hot Standby is PostgreSQL-speak for MySQL-style master/slave replication for scaling your reads. # 28th October 2009, 9:02 am
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. Released under the AGPL. # 16th July 2009, 10:30 am
PostgreSQL Development Priorities. The top two for 8.4 are “Simple built-in replication” and “Upgrade-in-place”, Josh Berkus is seeking feedback on priorities for future work on 8.5. # 28th May 2009, 8:08 pm
[Drizzle] won’t be a get-out-of-jail-free card for very write-heavy applications but I bet it will do wonders for heavily replicated, heavily federated, read-heavy architectures (you know, normal stuff).
What happened to Hot Standby? Hot Standby (the ability to have read-only replication slaves) has been dropped from PostgreSQL 8.4 and is now scheduled for 8.5. “Making hard decisions to postpone features which aren’t quite ready is how PostgreSQL makes sure that our DBMS is ”bulletproof“ and that we release close to on-time every year”. # 8th March 2009, 9:28 am
