Combines data of both inputs. The output will contain items of input 1 and input 2.

Keeps data of input 1 if it does find a match with data of input 2.

Merges data of both inputs. The output will contain items of input 1 merged with data of input 2. Merge happens depending on the index of the items. So first item of input 1 will be merged with first item of input 2 and so on.

Merges data of both inputs. The output will contain items of input 1 merged with data of input 2. Merge happens depending on a defined key.

Merges each value of one input with each value of the other input. The output will contain (m * n) items where (m) and (n) are lengths of the inputs.

Passes through data of one input. The output will contain only items of the defined input.

Keeps data of input 1 if it does NOT find match with data of input 2.

Waits till data of both inputs is available and will then output a single empty item. If supposed to wait for multiple nodes they have to get attached to input 2. Node will not output any data.
