The AWS Simple Queue Service (SQS) sink connector pulls data from Pulsar topics and persists data to AWS SQS.

How to get

You can get the SQS sink connector using one of the following methods:

Download the NAR package from here.
Build it from the source code.
1. Clone the source code to your machine.
```
git clone https://github.com/streamnative/pulsar-io-sqs
```
2. Assume that PULSAR_IO_SQS_HOME is the home directory for the pulsar-io-sqs repo. Build the connector in the ${PULSAR_IO_SQS_HOME} directory.
```
mvn clean install -DskipTests
```
  After the connector is successfully built, a NAR package is generated under the target directory.
```
ls target
pulsar-io-sqs-2.7.3.8-rc-3.nar
```

How to configure

Before using the SQS sink connector, you need to configure it.

You can create a configuration file (JSON or YAML) to set the following properties.

Name	Type	Required	Default	Description
`awsEndpoint`	String	false	" " (empty string)	AWS SQS end-point URL. It can be found at here.
`awsRegion`	String	true	" " (empty string)	Supported AWS region. For example, us-west-1, us-west-2.
`awsCredentialPluginName`	String	false	" " (empty string)	Fully-qualified class name of implementation of `AwsCredentialProviderPlugin`.
`awsCredentialPluginParam`	String	true	" " (empty string)	JSON parameter to initialize `AwsCredentialsProviderPlugin`.
`queueName`	String	true	" " (empty string)	Name of the SQS queue that messages should be read from or written to.

Example

JSON

 {
     "tenant": "public",
     "namespace": "default",
     "name": "sqs-sink",
     "inputs": [
       "test-queue-pulsar"
     ],
     "archive": "connectors/pulsar-io-sqs-2.7.3.8-rc-3.nar",
     "parallelism": 1,
     "configs":

         "awsCredentialPluginName": "",
         "awsCredentialPluginParam": '{"accessKey":"myKey","secretKey":"my-Secret"}'
     }
 }

YAML

tenant: "public"
namespace: "default"
name: "sqs-sink"
inputs: 
   - "test-queue-pulsar"
archive: "connectors/pulsar-io-sqs-2.7.3.8-rc-3.nar"
parallelism: 1

configs:
   awsEndpoint: "https://sqs.us-west-2.amazonaws.com"

   queueName: "test-queue"
   awsCredentialPluginName: ""
   awsCredentialPluginParam: '{"accessKey":"myKey","secretKey":"my-Secret"}'

How to use

You can use the SQS sink connector as a non built-in connector or a built-in connector as below.

Use as non built-in connector

If you already have a Pulsar cluster, you can use the SQS sink connector as a non built-in connector directly.

This example shows how to create an SQS sink connector on a Pulsar cluster using the pulsar-admin sinks create command.

PULSAR_HOME/bin/pulsar-admin sinks create \
--archive pulsar-io-sqs-2.7.3.8-rc-3.nar \
--sink-config-file sqs-sink-config.yaml \
--classname org.apache.pulsar.ecosystem.io.sqs.SQSSink \
--name sqs-sink

Use as built-in connector

You can make the SQS sink connector as a built-in connector and use it on a standalone cluster, on-premises cluster, or K8S cluster.

Standalone cluster

This example describes how to use the SQS sink connector to pull data from Pulsar topics and persist data to SQS in standalone mode.

Prepare SQS service.
For more information, see Getting Started with Amazon SQS.

Copy the NAR package of the SQS connector to the Pulsar connectors directory.

cp pulsar-io-sqs-2.7.3.8-rc-3.nar PULSAR_HOME/connectors/pulsar-io-sqs-2.7.3.8-rc-3.nar

Start Pulsar in standalone mode.
```
PULSAR_HOME/bin/pulsar standalone
```

Run the SQS sink connector locally.

PULSAR_HOME/bin/pulsar-admin sink localrun \
--sink-type sqs \
--sink-config-file sqs-sink-config.yaml

Send messages to Pulsar topics.

PULSAR_HOME/bin/pulsar-client produce public/default/test-queue-pulsar --messages hello -n 10

Consume messages from the SQS queue using the AWS SQS CLI tool.
```
aws sqs receive-message --queue-url ${QUEUE_URL} --max-number-of-messages 10
```
Now you can see the messages containing "Hello From Pulsar" from AWS SQS CLI.

On-premises cluster

This example explains how to create an SQS sink connector in an on-premises cluster.

Copy the NAR package of the SQS connector to the Pulsar connectors directory.

cp pulsar-io-sqs-2.7.3.8-rc-3.nar $PULSAR_HOME/connectors/pulsar-io-sqs-2.7.3.8-rc-3.nar

Reload all built-in connectors.

PULSAR_HOME/bin/pulsar-admin sinks reload

Check whether the SQS sink connector is available on the list or not.
```
PULSAR_HOME/bin/pulsar-admin sinks available-sinks
```

Create an SQS sink connector on a Pulsar cluster using the pulsar-admin sinks create command.

PULSAR_HOME/bin/pulsar-admin sinks create \
--sink-type sqs \
--sink-config-file sqs-sink-config.yaml \
--name sqs-sink

K8S cluster

Build a new image based on the Pulsar image with the SQS sink connector and push the new image to your image registry. This example tags the new image as streamnative/pulsar-sqs:2.7.3.8-rc-3.

FROM apachepulsar/pulsar-all:2.7.3.8-rc-3
RUN curl https://github.com/streamnative/pulsar-io-sqs/releases/download/v2.7.3.8-rc-3/pulsar-io-sqs-2.7.3.8-rc-3.nar -o /pulsar/connectors/pulsar-io-sqs-2.7.3.8-rc-3.nar

Extract the previous --set arguments from K8S to the file pulsar.yaml.
```
helm get values <release-name> > pulsar.yaml
```
Replace the images section in the pulsar.yaml file with the images section of streamnative/pulsar-sqs:2.7.3.8-rc-3.
Upgrade the K8S cluster with the pulsar.yaml file.
```
helm upgrade <release-name> streamnative/pulsar \
    --version <new version> \
    -f pulsar.yaml
```
