CCL Project Basics
Before you begin a project, be familiar with the order in which statements and clauses must appear, project development, and the basics of streams and windows.
- Order of Elements
Determine the order of CCL project elements based on clause and statement syntax definitions and limitations.
- Comparing Streams, Windows, and Delta Streams
Streams, windows, and delta streams offer different characteristics and features, but also share common designation, visibility, and column parameters.
- Windows
A window is a stateful element that can be named or unnamed, and retains rows based on a defined retention policy.
- Delta Streams
Delta streams are stateless elements that can understand all opcodes.
- Schemas
A schema defines the structure of data rows in a stream or window.
- Stores
Set store defaults, or choose a log store or memory store to specify how data from a window is saved.
- Working with Adapters
Determine the prerequisites for using Event Stream Processor-supplied adapters and custom adapters.
