# Manage sinks

> To stream data out of RisingWave, you must create a sink. A sink refers to an external target that you can send data to. You can deliver data to downstream systems via our sink connectors.

For the complete list of supported sink connectors and data formats, see [Data delivery](/delivery/overview) in the RisingWave documentation.

## Create a sink

You can create a sink using SQL command to deliver processed data to an external target.

<Info>
  **Data Security**

  * All data ingested through sources or sinks is encrypted in transit using TLS
  * Data stored within RisingWave is encrypted at rest:
    * AWS S3: Using AWS default encryption keys
    * EBS volumes: Using KMS managed keys with automatic rotation
</Info>

Refer to [CREATE SINK](/sql/commands/sql-create-sink) in the RisingWave Database documentation.

## Check a sink

1. Go to [**Project**](https://cloud.risingwave.com/project/home/).
2. Specify the project and click its **Workspace**.
3. Click **Sink** tab to view sinks.

## Drop a sink

If you no longer need to deliver data to a sink, you can drop the sink using SQL command.

Refer to [DROP SINK](/sql/commands/sql-drop-sink) in the RisingWave Database documentation.
