Alvin Richards: MongoDB

• Trade-off: scale vs. functionality. MongoDB tries to have good functionality and good scalability.
• Auto-sharding to maintain equilibrium between shards
• Scalable datastore != scalable application: use of datastore may still be non-scalable (e.g. many queries across all shards)
• Get low latency by ensuring shard data is always in memory: datastore

This is somewhat of a follow-up to the previous article setting up a new rails app with git.

For the impatient

Set up the new bare repo on the server:
