Which database to decide upon? Any comparisions?
- Existing: postgresql
- Issues
- Not easily scalable horizontal. Needs sharding etc
- Clustering does not solve the data growth problem
- Looking for: Any database that is easily horizontally scalable
- Cassandra (Twitter uses that?)
- MongoDB (rapidly gaining popularity)
- Voldemart
- Other?
- Why?
- Data growing with snowball effect
- existing postgresql locks table etc for vaccuum tasks periodically
- Archiving data is tideous currently
- Human interaction involved in existing archive, vaccuum, ... process periodically
- Need a 'set it. forget it. just add another server when data grows more.' type of solution
