Known Issues for Event Stream Processor Studio

When you convert a project from AleriML to CCL and the project contains Windows file paths, you cannot run the resulting project in Studio Visual Authoring.

This is because Windows file paths use a single backslash character (\), which the CCL compiler views as an escape character. This condition prevents the project from loading in Studio Visual Authoring. To load the project, manually replace the single backslashes with double backslashes (\\). For example, change C:\Temp\store to C:\\Temp\\store.

If a join has two input connectors and one connector is deleted, the columns belonging to the deleted input connector are not deleted.

Manually remove the column expressions belonging to the deleted input connector.

When defining adapter properties in Studio, you can select a specific file from the file system. Windows file paths include a single backslash (\) as the file separator. However, the CCL compiler views the backslash as an escape character and therefore interprets the path incorrectly.

Therefore, when working with Windows paths within Studio, manually change the single backslash file separator to a double backslash (\\).

When using the Connector tool in the Visual Editor, you can connect from a stream or window to a named schema but you cannot connect from a named schema to a stream or window.

Deleting the key column from a named schema does not update the CCL editor. The CCL editor shows the column as a primary key and the project does not compile successfully.

Inline schema does not cause this problem. Update the project in the CCL editor to compile successfully.

Setting the dir property to configure schema discovery for the File CSV Input and File XML Input adapters fails to set the file property.

Set the dir property and the file property separately to be able to browse and select the specific file, and then use schema discovery.

When running example projects from the Learning perspective, the Stream View is empty for some streams.

If you are running a project in the Learning perspective and you are working with a small data set, work around this issue by changing the stream view pulsed subscribe interval value to 0.

Set the interval back to its default value of 1 before working with any other projects.
