Create Rendezvous (G Dataflow)

Name of the rendezvous that you want to create or search for.

If you specify name, the node first searches for an existing rendezvous with the same name and returns a reference to the rendezvous if it exists. If an existing rendezvous with the same name does not exist and return existing is False, the node creates a new rendezvous and returns a reference.

Default: Empty string — The node creates an unnamed rendezvous.

Number of tasks that initially meet at the rendezvous to continue execution. If a named rendezvous already exists, you cannot use this parameter to resize the rendezvous. Use the Resize Rendezvous node to resize a named rendezvous.

Default: 2

A Boolean value that specifies whether the rendezvous must already exist for this node to succeed.

Default: False

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

Reference to an existing or newly created rendezvous.

A Boolean value that indicates whether the node created a new rendezvous.

Error information.

The node produces this output according to standard error behavior.
