   Maps raw source event to Context where default "input" variable represents the event.

   Raw

   - type of raw event that is generated by flink source function.

   processId

   - id of the process or flink job, used to setup name of created Context

4. class BasicFlinkContextInitializer[Raw] extends FlinkContextInitializer[Raw]

   

   Basic implementation of context initializer.

   Basic implementation of context initializer. Used when raw event produced by SourceFunction does not need further transformations and should be assigned to default "input" variable directly.

   Raw

   - type of raw event that is generated by flink source function.

   Basic implementation of context initializer for sources based on pl.touk.nussknacker.engine.api.context.transformation.GenericNodeTransformation. Requires proper definition of outputVariableType.

6. trait BasicFlinkSink extends FlinkSink with ExplicitUidInOperatorsSupport

   

   This is basic Flink sink, which just uses *output* expression from sink definition

7. trait BasicFlinkSource[Raw] extends FlinkSource[Raw] with FlinkIntermediateRawSource[Raw]

   

   Typical source with methods specific for Flink, user has only to define Source function.

   Typical source with methods specific for Flink, user has only to define Source function.

   Raw

   - type of raw event that is generated by flink source function. This is needed to handle e.g. syntax suggestions in UI (in sources with explicite @MethodToInvoke).

8. abstract class FlinkContextInitializer[Raw] extends Serializable

   

   FlinkContextInitializer provides definition of a map function that transforms raw event to Context.

   FlinkContextInitializer provides definition of a map function that transforms raw event to Context.

   Raw

   - type of raw event that is generated by flink source function.

9. trait FlinkCustomJoinTransformation extends AnyRef

   

   Join functionality is not complete, many things are not implemented yet - validation context passed to both BranchExpression and JoinContextTransformationDef should be taken from incoming branches - cannot test&generate test data from other branches

   Join functionality is not complete, many things are not implemented yet - validation context passed to both BranchExpression and JoinContextTransformationDef should be taken from incoming branches - cannot test&generate test data from other branches

   Additionally, a lot of refactoring should be done - removing tree structures - should CustomNode and Join be sth different in ConfigCreator

   Some important TODOs are marked with TODO JOIN

13. trait FlinkIntermediateRawSource[Raw] extends ExplicitUidInOperatorsSupport

    

    Source with typical source stream trasformations:

    Source with typical source stream trasformations:

    1. adds source using provided SourceFunction (here raw source produces raw data) 2. sets UID 3. assigns timestamp and watermarks 4. initializes Context that is streamed within output DataStream (here raw data are mapped to Context) It separates raw event data produced by SourceFunction and data released to the stream as Context variables. By default it uses basic "single input value" implementation of initializer, see BasicFlinkContextInitializer.
