1. Real-Time Data Processing for LLMs with SQS Event Subscription


    To set up real-time data processing for Large Language Models (LLMs) with Amazon Simple Queue Service (SQS) event subscription, you'll want to create an infrastructure that includes the following key components:

    1. Amazon SQS: A managed message queue service that lets you decouple and scale microservices, distributed systems, and serverless applications. You would use SQS to receive and store messages that trigger the processing of data.

    2. AWS Lambda: A serverless compute service that lets you run code without provisioning or managing servers. AWS Lambda can automatically execute code in response to multiple events, such as modifications to data in an Amazon S3 bucket or updates to an Amazon DynamoDB table.

    3. Event Source Mapping: Associating your AWS Lambda function with the SQS queue so that messages in the queue can trigger the execution of your function.

    Implementing such an infrastructure in Pulumi using Python involves defining these resources and setting up the appropriate permissions for them to interact. Below is an illustrative Pulumi program that sets this up:

    import pulumi import pulumi_aws as aws # Define an AWS SQS queue to receive messages. sqs_queue = aws.sqs.Queue('llm-data-queue', visibility_timeout_seconds=180) # Timeout to process a message. # Define an AWS Lambda function that will process messages from the SQS queue. lambda_function = aws.lambda_.Function('data-processing-func', runtime=aws.lambda_.Runtime.PYTHON3_8, code=pulumi.AssetArchive({ '.': pulumi.FileArchive('./lambda') # Assuming your Lambda code is in the 'lambda' directory. }), handler='lambda_function.handler', # Assuming your handler function is named 'handler' in 'lambda_function.py'. role=some_lambda_role.arn, # You'll need to create an IAM role with the necessary permissions. ) # Grant the Lambda function permission to receive messages from the SQS queue. sqs_policy = aws.lambda_.Permission('lambda-sqs-policy', action='lambda:InvokeFunction', function=lambda_function.name, principal='sqs.amazonaws.com', source_arn=sqs_queue.arn, ) # Create an event source mapping to trigger the Lambda function for each new message. event_source_mapping = aws.lambda_.EventSourceMapping('llm-trigger', batch_size=10, # Number of messages to send to the Lambda at once. event_source_arn=sqs_queue.arn, function_name=lambda_function.name, ) # An IAM role example that could be used by the Lambda function. # This role needs to have enough permissions to interact with the necessary AWS services. some_lambda_role = aws.iam.Role('lambda-execution-role', assume_role_policy=json.dumps({ "Version": "2012-10-17", "Statement": [{ "Action": "sts:AssumeRole", "Effect": "Allow", "Principal": { "Service": "lambda.amazonaws.com", }, }], }), ) # Example policy for the role to allow it to log to CloudWatch. log_policy = aws.iam.RolePolicy('lambda-log-policy', role=some_lambda_role.id, policy=pulumi.Output.all(sqs_queue.arn).apply(lambda arn: json.dumps({ "Version": "2012-10-17", "Statement": [{ "Effect": "Allow", "Action": [ "logs:CreateLogGroup", "logs:CreateLogStream", "logs:PutLogEvents" ], "Resource": "arn:aws:logs:*:*:*" }, { "Effect": "Allow", "Action": "sqs:ReceiveMessage", "Resource": arn }], })), ) # Export the SQS queue URL and ARN so that you can send messages to your queue. pulumi.export('sqs_queue_url', sqs_queue.id) pulumi.export('sqs_queue_arn', sqs_queue.arn)

    In the program above, we first created an SQS queue where the data can be sent for processing. Next, we defined a Lambda function with a specified runtime and pointed it at the location of our code. The IAM role and policy ensure that the Lambda function has the necessary permissions to interact with other AWS services and log its output.

    We then set up an event source mapping to connect the SQS queue with our Lambda function, so it gets triggered whenever there's a new message. The batch_size setting determines how many messages the Lambda function will receive at once.

    Lastly, we exported the SQS queue URL and ARN, which are useful if you need to interact with your queue from other services or send messages to it programmatically.

    This Pulumi program is a starting point for setting up real-time data processing for LLMs with SQS event subscription. Before running this code, you'll need to have the AWS Pulumi package installed and the AWS CLI configured with credentials and default region.
