rewrites

Type Members

1. trait Coalesce[IN[_]] extends AnyRef

   

   Rewrites adjacent nodes.

2. trait CoalesceInstances extends AnyRef

   

3. class CoalesceT[T[_[_]]] extends TTypes[T]

   

4. trait ExpandDirs[IN[_]] extends AnyRef

   

   Converts any {Shifted}Read containing a directory to a union of all the files in that directory.

5. abstract class ExpandDirsInstances extends AnyRef

   

6. trait Normalizable[F[_]] extends Serializable

   

7. trait NormalizableInstances extends AnyRef

   

8. class NormalizableT[T[_[_]]] extends TTypes[T]

   

9. class Optimize[T[_[_]]] extends TTypes[T]

   

10. trait PreferProjection[F[_], T, B[_]] extends AnyRef

    

    A rewrite that, where possible, replaces map key deletion with construction of a new map containing the keys in the complement of the singleton set consisting of the deleted key.

    A rewrite that, where possible, replaces map key deletion with construction of a new map containing the keys in the complement of the singleton set consisting of the deleted key.

    Only applies to maps where all keys are known statically.

11. sealed abstract class PreferProjectionInstances extends AnyRef

    

12. class Rewrite[T[_[_]]] extends TTypes[T]

    

13. trait ShiftRead[F[_]] extends AnyRef

    

    This optional transformation changes the semantics of Read.

    This optional transformation changes the semantics of Read. The default semantics return a single value, whereas the transformed version has an implied LeftShift and therefore returns a set of values, which more closely matches the way many data stores behave.

14. trait ShiftReadDir[F[_]] extends AnyRef

    

    Like ShiftRead, but only applies when the path is a directory, leaving file reads untouched.

15. sealed abstract class ShiftReadDirInstances extends ShiftReadDirInstances0

    

16. sealed abstract class ShiftReadDirInstances0 extends AnyRef

    

17. class SimplifiableProjectionT[T[_[_]]] extends TTypes[T]

    

18. trait SimplifyJoin[F[_]] extends AnyRef

    

    Replaces ThetaJoin with EquiJoin, which is often more feasible for connectors to implement.

    Replaces ThetaJoin with EquiJoin, which is often more feasible for connectors to implement. It potentially adds a Filter iff there are conditions in the ThetaJoin that can not be handled by an EquiJoin.

19. trait SimplifyProjection[F[_]] extends AnyRef

    

    This optional transformation changes the semantics of Read.

    This optional transformation changes the semantics of Read. The default semantics return a single value, whereas the transformed version has an implied LeftShift and therefore returns a set of values, which more closely matches the way many data stores behave.

22. sealed trait UnicoalesceQC[T[_[_]], C <: CoM] extends Unicoalesce[T, C]

    

23. sealed trait UnicoalesceSR[T[_[_]], C <: CoM] extends Unicoalesce[T, C]

    

24. sealed trait UnicoalesceTJ[T[_[_]], C <: CoM] extends Unicoalesce[T, C]

    

25. sealed trait Unirewrite[T[_[_]], C <: CoM] extends AnyRef
