CREATE SINK

Use the CREATE SINK command to create a sink. A sink is an external target where you can send data processed in RisingWave. You can create a sink from a table or source, or a materialized view.

If your goal is to create an append-only sink, you can use the emit-on-window-close policy when creating the materialized view that you want to sink data from. For details about the policy, see Emit on window close.

Syntax

CREATE SINK [ IF NOT EXISTS ] sink_name
[FROM sink_from | AS select_query]
WITH (
connector='connector_name',
connector_parameter = 'value', ...
);
