Abstract
A database query optimizer optimizes a query that uses multiple networks. The database query optimizer optimizes a query that uses multiple networks to satisfy the query by splitting the query execution to use multiple networks. Thus, the query optimizer rewrites or optimizes a query to execute on multiple nodes or networks to more efficiently execute the query and reduce network traffic on a network. The query optimizer uses plan cache statistics to determine whether to use multiple networks to optimize the query.
