    Given our target Cassandra based branch, we remove the node which draws data from cassandra (DataSourceScanExec) and replace it with the passed directJoin plan instead.

    Given our target Cassandra based branch, we remove the node which draws data from cassandra (DataSourceScanExec) and replace it with the passed directJoin plan instead.

    INPUT :

    //directJoin: DirectJoinPlan// DirectJoin <-- GetKeyOperations

    //plan: Optimized CassandraScanBranch/ OtherOperations <-- CassandraScan

    OUTPUT:

    OtherOperations <-- DirectJoin <-- GetKeyOperations

    The output of (plan) is not changed, but its children should be changed.

    This should only be called on optimized Physical Plans
