Editing Bindings in Project Configuration

Configure bindings between input streams or windows in a project to output streams or windows in other projects.

Prerequisites

You must have verified that the streams or windows you want to bind have:

Compatible schema.
The same datatype for each field name.
The same column order.
The same number of columns.

Task

Projects can be bound to other projects, allowing one project's input stream or window to receive its input from the output stream or window of another project. Binding projects is similar to attaching an input adapter to an input stream or window, but is more efficient as it directly connects the output of one project to the input of the other. Stream binding is only supported from the receiving project. You cannot initiate a binding from the publishing side.

Bindings can be local, within the same cluster, or can connect a project in one cluster to a project in a different cluster. Binding information is specified in the project configuration (CCR) file so that binding references may be changed at runtime, allowing the project to be used in multiple environments.

In the CCR Project Configuration editor, select the Bindings tab.
To add a binding, click Add, or to display a list of available streams/windows, click Discover.

To configure individual binding items, use the Binding Details pane on the right side of the CCR Project Configuration editor.

Field	Description
Binding name	(Optional) Apply a name to the binding.
Local stream/window	Enter the local stream/window information (for example, localStream1) or click Discover to view and select from a list of running streams/windows.
Cluster	Select the cluster to bind to. Note: You must have previously defined one or more clusters in the Run-Test perspective and added the cluster of interest in the Cluster tab.
Workspace	Enter the workspace data (for example, ws1) or click Discover to view and select from a list of running workspaces.
Project	Enter the project to access (for example, project1) or click Discover to view and select from a list of running projects.
Remote stream/window	Enter the remote stream/window information (for example, remoteStream1) or click Discover to view and select from a list of running streams/windows.

To remove a binding, select it, and click Remove.
