Applies to: FAST Search Server 2010

Host distribution rules are used to associate a host with a specific crawl database. By default, hosts are load balanced across crawl databases based on space availability. However, you may want to assign a host to a specific crawl database for availability and performance optimization. For more information about crawl databases, see Add or remove a crawl database (FAST Search Server 2010 for SharePoint).
