Event Subscription and Sending

The DolphinDB 3.00.0 introduces a new feature - Complex Event Processing (CEP) - to find patterns in event data that enable detection of opportunities and threats. To better interact with server, Python API 3.0.0.0 provides the cep module to define, send, and subscribe to events.

This section describes event-related operations, including:

• Defining events.

• Writing events to the heterogeneous stream table as a data source for the CEP engine on the DolphinDB server.

• Subscribing to events in the heterogeneous stream table output by the CEP engine on the DolphinDB server.

For more details, see the "Complex Event Processing" chapter of the DolphinDB server user manual.
