toRel

public RelNode toRel(RelOptCluster cluster,
                     RelOptConnection connection)

Description copied from interface: RelOptTable

Converts this table into a relational expression.

The planner calls this method to convert a table into an initial relational expression, generally something abstract, such as a TableAccessRel, then optimizes this expression by applying rules to transform it into more efficient access methods for this table.

Parameters:

cluster - the cluster the relational expression will belong to

connection - the parse tree of the expression which evaluates to a connection object
