DBD::Multiplex
DBD::Multiplex
- Connects to multiple databases at once (via DBI)
- Executes each statement on each database by default
Could be configured to:
- insert into all databases but select from one
- fallback to alternate database if primary is unavailable
- select round-robin / or at random to distribute load
- select from all and check results (pick most common)
Can be used with DBD::Proxy, either above or below
May also acquire fancy caching in later versions
