Features cdc ( Source ) The CDC source receives events when change events (i.e., INSERT, UPDATE, DELETE) are triggered for a database table. Events are received in the 'key-value' format. There are two modes you could perform CDC: Listening mode and Polling mode. In polling mode, the datasource is periodically polled for capturing the changes. The polling period can be configured. In polling mode, you can only capture INSERT and UPDATE changes. On listening mode, the Source will keep listening to the Change Log of the database and notify in case a change has taken place. Here, you are immediately notified about the change, compared to polling mode. The key values of the map of a CDC change event are as follows. For 'listening' mode:     For insert: Keys are specified as columns of the table.     For delete: Keys are followed by the specified table columns. This is achieved via 'before '. e.g., specifying 'before X' results in the key being added before the column named 'X'.    &n","default_branch":null,"files":null,"tree":[],"storefront":"/r/siddhi-io","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/siddhi-io/siddhi-io-cdc/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
