High Availability, Load Balancing, and Replication
Many of the above solutions allow multiple servers to handle multiple
queries, but none allow a single query to use multiple servers to
- complete faster. This allows multiple servers to work concurrently
- on a single query. This is usually accomplished by splitting the
- data among servers and having each server execute its part of the
- query and return results to a central server where they are combined
