Overview

In this project, we will set up an Amazon Bedrock agent with an action group that can translate natural language queries (NLQ) into SQL queries. The agent will query an Amazon Athena database, but the concept can be extended to most SQL databases.

For those who prefer an Infrastructure-as-Code (IaC) solution, we provide an AWS CloudFormation template that will deploy all the necessary resources. If you would like to deploy via AWS CloudFormation, please refer to the guide in the section below.

Alternatively, this README will walk you through the step-by-step process to set up the Amazon Bedrock agent manually using the AWS Console.

Solution Overview

This solution integrates Amazon Bedrock agents, AWS Lambda, Amazon Athena, and AWS Glue to process real-time user queries by translating natural language inputs into SQL queries to interact with data stored in Amazon S3. The Amazon Bedrock agent, acting as the central orchestrator, receives user inputs from an interface hosted on an EC2 instance. Using a chain-of-thought mechanism, it breaks down complex queries and delegates tasks to the appropriate AI models and services. The agent utilizes an action group, defined by OpenAPI schemas, to structure and execute multiple tasks. This action group interacts with a Lambda function, which processes SQL queries generated by the Bedrock agent and runs them through Amazon Athena for analysis.

AWS Glue supports this process by reading unstructured data from Amazon S3, creating structured tables through its Data Catalog and crawlers, making it ready for Athena's queries. The results of these queries are stored back in Amazon S3 for easy access. The entire system is designed to be serverless, scalable, and secure, providing a flexible solution to handle diverse and complex queries with minimal infrastructure overhead.

Prerequisites

  • An active AWS Account.
  • Familiarity with AWS services like Amazon Bedrock, Amazon S3, AWS Lambda, Amazon Athena, and Amazon EC2.
  • Access will need to be granted to the Titan Embeddings G1 - Text and Anthropic: Claude 3 Haiku model from the Amazon Bedrock console.

  1. The Amazon Bedrock agent endpoint serves as the bridge between the user's application that runs on an Amazon EC2 instance on AWS and the Amazon Bedrock agent, facilitating the transfer of input data in real-time. This setup is essential for capturing inputs that trigger the agent driven process. Natural language is used to query data, and return the response back to the user via the user interface.

  2. An instruction prompt is provided to the Amazon Bedrock agent to help with orchestration. The Amazon Bedrock agent orchestrates the tasks by interpreting the input prompt and delegating specific actions to the LLM.

  3. Collaboration with the task orchestrater in the previous step enables the LLM to process complex queries and generate outputs that align with the user's objectives. The chain of thought mechanism ensures that each step in the process is logically connected, leading to precise action execution. The model processes the user's natural language input, translating it into actionable SQL queries, which are then used to interact with data services.

  4. The main purpose of an action group in an Amazon Bedrock agent is to provide a structured way to perform multiple actions in response to a user's input or request. This allows the agent to take a series of coordinated steps to address the user's needs, rather than just performing a single action. This action group includes an OpenAPI schema which is needed so that the Amazon Bedrock agent knows the format structure and parameters needed for the action group to interact with the compute layer, in this case, a Lambda function.

  5. The AWS Lambda function acts as the execution engine, processing the SQL query and interfacing with Amazon Athena. Proper configuration of resource policies and permissions is critical to ensure secure and efficient operations, maintaining the integrity of the serverless compute environment.

  6. Amazon Athena is a serverless, query service that makes it easy to analyze data in Amazon S3 via AWS Glue using standard SQL. This optimized search engine assists in querying unstructured data from Amazon S3. All results from an SQL query is stored in an Amazon S3 bucket.

  7. AWS Glue will read the unstructured data from Amazon S3, then create tables that will be used by Amazon Athena for querying. The use of crawlers and the AWS Glue Data Catalog simplifies data management, making it easier to integrate and query diverse datasets, in this case an Amazon S3 bucket.

  8. Company data is loaded into Amazon S3, which serves as the data source for AWS Glue. It is the location where the raw, unstructured data is stored. In this example, we are using .csv files, but virtually any format can be used.

Grant Model Access

  • We will need to grant access to the models that will be needed for the Amazon Bedrock agent. Navigate to the Amazon Bedrock console, then on the left of the screen, scroll down and select Model access. On the right, select the orange Enable specific models button.

Model access

  • To have access to the required models, scroll down and select the checkbox for the Titan Embedding G1 - Text and Anthropic: Claude 3 Haiku model. Then in the bottom right, select Next, then Submit.

  • After, verify that the Access status of the Models are green with Access granted.

Access granted

Deploy resources via AWS Cloudformation:

Here are the instructions to deploy the resources within your environment:

Step 1

Download the Cloudformation templates from below, then deploy in order:

Click here to download template 1 🚀 - 1 - Athena-Glue-S3 Stack

  • This template will create Amazon Athena, AWS Glue, and an Amazon S3 bucket. Then, it uploads customer and procedure .csv files to the S3 bucket.

Click here to download template 2 🚀 - 2 - Agent-Lambda Stack

  • This next template will create an Amazon bedrock agent, action group, with an associated Lambda function.

Click here to download template 3 🚀 - 3 - EC2 UI Stack

  • This template will be used to deploy an EC2 instance that will run the code for the Streamlit UI.

Step 2

  • In your mangement console, search, then go to the CloudFormation service.
  • Create a stack with new resources (standard)

Create stack

  • Prepare template: Choose existing template -> Specify template: Upload a template file -> upload the template downloaded from the previous step.

Create stack config

  • Next, Provide a stack name like athena-glue-s3. Keep the instance type on the default of t3.small, then go to Next.

Stack details

  • On the Configure stack options screen, leave every setting as default, then go to Next.

  • Scroll down to the capabilities section, and acknowledge the warning message before submitting.

  • Once the stack is complete, follow the same process and deploy the remaing two templates. After, go to the next step.

Stack complete

Step 3

  • Update Amazon Athena data source for SQL results. Navigate to the Amazon Athena management console. Then, select Launch query editor. athena 1

  • Select the Settings tab, then the Manage button. athena 2

  • Browse your Amazon S3 buckets, and select the radio button for S3 bucket sl-athena-output-{Alias}-{Account-Id}-{Region}. After, save the changes. athena 2.5

athena 3

Testing the Bedrock Agent

  • Navigate to the Bedrock console. Go to the toggle on the left, and under Builder tools select Agents, then the athena-agent that was created.

navigate to agent

  • In the management console on the right, you have a test user interface. Enter prompts in the user interface to test your Bedrock agent.

Agent test

  • Example prompts for Action Groups:

    1. Show me all of the procedures in the imaging category that are insured.

    2. Show me all of the customers that are vip, and have a balance over 200 dollars.

    3. Return to me the number of procedures that are in the laboratory category.

    4. Get me data of all procedures that were not insured, with customer names.

  • If you would like to launch the Streamlit app user interface, refer to Step 7 below to configure the EC2 instance.

Step-by-step Configuration and Setup

Step 1: Creating S3 Buckets

  • Make sure that you are in the us-west-2 region. If another region is required, you will need to update the region in the invoke_agent.py file on line 24 of the code.
  • Domain Data Bucket: Create an S3 bucket to store the domain data. For example, call the S3 bucket athena-datasource-{alias}. We will use the default settings. (Make sure to update {alias} with the appropriate value throughout the README instructions.)

Bucket create 1

  • Next, we will download .csv files that contain mock data for customers and procedures. Open up a terminal or command prompt, and run the following curl commands to download and save these files to the Documents folder:

For Mac

curl https://raw.githubusercontent.com/build-on-aws/bedrock-agent-txt2sql/main/S3data/mock-data-customers.csv --output ~/Documents/mock-data-customers.csv

curl https://raw.githubusercontent.com/build-on-aws/bedrock-agent-txt2sql/main/S3data/mock-data-procedures.csv --output ~/Documents/mock-data-procedures.csv

For Windows

curl https://raw.githubusercontent.com/build-on-aws/bedrock-agent-txt2sql/main/S3data/mock-data-customers.csv --output %USERPROFILE%\Documents\mock-data-customers.csv

curl https://raw.githubusercontent.com/build-on-aws/bedrock-agent-txt2sql/main/S3data/mock-data-procedures.csv --output %USERPROFILE%\Documents\mock-data-procedures.csv
  • These files are the datasource for Amazon Athena. Upload these files to S3 bucket athena-datasource-{alias}. Once the documents are uploaded, please review them.

bucket domain data

  • Amazon Athena Bucket: Create another S3 bucket for the Athena service. Call it athena-destination-store-{alias}. You will need to use this S3 bucket when configuring Amazon Athena in the next step.

Step 2: Setup Amazon Athena

  • Search for the Amazon Athena service, then navigate to the Athena management console. Validate that the Query your data with Trino SQL radio button is selected, then press Launch query editor.

Athena query button

  • Before you run your first query in Athena, you need to set up a query result location with Amazon S3. Select the Settings tab, then the Manage button in the Query result location and encryption section.

Athena manage button

  • Add the S3 prefix below for the query results location, then select the Save button:
s3://athena-destination-store-{alias}

choose athena bucket.png

  • Next, we will create an Athena database. Select the Editor tab, then copy/paste the following query in the empty query screen. After, select Run:
CREATE DATABASE IF NOT EXISTS athena_db;

Create DB query

  • You should see query successful at the bottom. On the left side under Database, change the default database to athena_db, if not by default.

  • We'll need to create the customers table. Run the following query in Athena. (Remember to update the {alias} field):

CREATE EXTERNAL TABLE athena_db.customers (
  `Cust_Id` integer,
  `Customer` string,
  `Balance` integer,
  `Past_Due` integer,
  `Vip` string
)
ROW FORMAT DELIMITED 
FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n'
STORED AS TEXTFILE
LOCATION 's3://athena-datasource-{alias}/';
  • Open another query tab and create the procedures table by running this query. (Remember to update the {alias} field):
CREATE EXTERNAL TABLE athena_db.procedures (
  `Procedure_Id` string,
  `Procedure` string,
  `Category` string,
  `Price` integer,
  `Duration` integer,
  `Insurance` string,
  `Customer_Id` integer
)
ROW FORMAT DELIMITED 
FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n'
STORED AS TEXTFILE
LOCATION 's3://athena-datasource-{alias}/';
  • Your tables for Athena within editor should look similar to the following:

Athena editor env created

  • Now, lets quickly test the queries against the customers and procedures table by running the following two example queries below:
SELECT *
FROM athena_db.procedures
WHERE insurance = 'yes' OR insurance = 'no';

procedures query

SELECT * 
FROM athena_db.customers
WHERE balance >= 0;

customers query

  • If tests were succesful, we can move to the next step.

Step 3: Lambda Function Configuration

  • Create a Lambda function (Python 3.12) for the Bedrock agent's action group. We will call this Lambda function bedrock-agent-txtsql-action.

Create Function

Create Function2

  • Copy the provided code from here, or from below into the Lambda function.
import boto3
from time import sleep

# Initialize the Athena client
athena_client = boto3.client('athena')

def lambda_handler(event, context):
    print(event)

    def athena_query_handler(event):
        # Fetch parameters for the new fields

        # Extracting the SQL query
        query = event['requestBody']['content']['application/json']['properties'][0]['value']

        print("the received QUERY:",  query)
        
        s3_output = 's3://athena-destination-store-alias'  # Replace with your S3 bucket

        # Execute the query and wait for completion
        execution_id = execute_athena_query(query, s3_output)
        result = get_query_results(execution_id)

        return result

    def execute_athena_query(query, s3_output):
        response = athena_client.start_query_execution(
            QueryString=query,
            ResultConfiguration={'OutputLocation': s3_output}
        )
        return response['QueryExecutionId']

    def check_query_status(execution_id):
        response = athena_client.get_query_execution(QueryExecutionId=execution_id)
        return response['QueryExecution']['Status']['State']

    def get_query_results(execution_id):
        while True:
            status = check_query_status(execution_id)
            if status in ['SUCCEEDED', 'FAILED', 'CANCELLED']:
                break
            sleep(1)  # Polling interval

        if status == 'SUCCEEDED':
            return athena_client.get_query_results(QueryExecutionId=execution_id)
        else:
            raise Exception(f"Query failed with status '{status}'")

    action_group = event.get('actionGroup')
    api_path = event.get('apiPath')

    print("api_path: ", api_path)

    result = ''
    response_code = 200


    if api_path == '/athenaQuery':
        result = athena_query_handler(event)
    else:
        response_code = 404
        result = {"error": f"Unrecognized api path: {action_group}::{api_path}"}

    response_body = {
        'application/json': {
            'body': result
        }
    }

    action_response = {
        'actionGroup': action_group,
        'apiPath': api_path,
        'httpMethod': event.get('httpMethod'),
        'httpStatusCode': response_code,
        'responseBody': response_body
    }

    api_response = {'messageVersion': '1.0', 'response': action_response}
    return api_response
  • Then, update the alias value for the s3_output variable in the python code above. After, select Deploy under Code source in the Lambda console. Review the code provided before moving to the next step.

Lambda deploy

  • Now, we need to apply a resource policy to Lambda that grants Bedrock agent access. To do this, we will switch the top tab from code to configuration and the side tab to Permissions. Then, scroll to the Resource-based policy statements section and click the Add permissions button.

Permissions config

Lambda resource policy create

  • Enter arn:aws:bedrock:us-west-2:{aws-account-id}:agent/* . Please note, AWS recommends least privilage so only the allowed agent can invoke this Lambda function. A * at the end of the ARN grants any agent in the account access to invoke this Lambda. Ideally, we would not use this in a production environment. Lastly, for the Action, select lambda:InvokeAction, then Save.

Lambda resource policy

  • We also need to provide this Lambda function permissions to interact with an S3 bucket, and Amazon Athena service. While on the Configuration tab -> Permissions section, select the Role name:

Lambda role name 1

  • Select Add permissions -> Attach policies. Then, attach the AWS managed policies AmazonAthenaFullAccess, and AmazonS3FullAccess by selecting, then adding the permissions. Please note, in a real world environment, it's recommended that you practice least privilage.

Lambda role name 2

  • The last thing we need to do with the Lambda is update the configurations. Navigate to the Configuration tab, then General Configuration section on the left. From here select Edit.

Lambda role name 2

  • Update the memory to 1024 MB, and Timeout to 1 minute. Scroll to the bottom, and save the changes.

Lambda role name 2

Lambda role name 3

  • We are now done setting up the Lambda function

Step 4: Setup Bedrock agent and action group

  • Navigate to the Bedrock console. Go to the toggle on the left, and under Builder tools select Agents, then Create Agent. Provide an agent name, like athena-agent then Create.

agent create

  • For this next screen, agent description is optional. Use the default new service role. For the model, select Anthropic Claude 3 Haiku. Next, provide the following instruction for the agent:
You are a SQL developer creating queries for Amazon Athena. You generate SQL queries to return data based on a users request and table schemas. Here is how I want you to think step by step:

1. Query Decomposition and Understanding:
   - Analyze the user’s request to understand the main objective.
   - Break down reqeusts into sub-queries that can each address a part of the user's request, using the schema provided.

2. SQL Query Creation:
   - For each sub-query, use the relevant tables and fields from the provided schema.
   - Construct SQL queries that are precise and tailored to retrieve the exact data required by the user’s request.

3. Query Execution and Response:
   - Execute the constructed SQL queries against the Amazon Athena database.
   - Return the results exactly as they are fetched from the database, ensuring data integrity and accuracy. Include the query generated and results in the response.

It should look similar to the following:

agent instruction

  • Scroll to the top, then select Save.

  • Keep in mind that these instructions guide the generative AI application in its role as a SQL developer creating efficient and accurate queries for Amazon Athena. The process involves understanding user requests, decomposing them into manageable sub-queries, and executing these to fetch precise data. This structured approach ensures that responses are not only accurate but also relevant to the user's needs, thereby enhancing user interaction and data retrieval efficiency.

  • Next, we will add an action group. Scroll down to Action groups then select Add.

  • Call the action group query-athena. In the Action group type section, select Define with API schemas. For Action group invocations, set to Select an existing Lambda function. For the Lambda function, select bedrock-agent-txtsql-action.

  • For the Action group Schema, we will choose Define with in-line OpenAPI schema editor. Replace the default schema in the In-line OpenAPI schema editor with the schema provided below. You can also retrieve the schema from the repo here. After, select Add. (This API schema is needed so that the bedrock agent knows the format structure and parameters needed for the action group to interact with the Lambda function.)

  • Now we will need to modify the Advanced prompts. While your still in edit mode, Scroll down to the advanced prompts section, and select Edit.

ad prompt btn

  • In the Advanced prompts, navigate to the Orchestration tab. Enable the Override orchestration template defaults option. Activate orchestration template should be enabled by default. Otherwise, enable it.

  • In the Prompt template editor, go to line 19-20, make a line space, then copy/paste the following prompt (Make sure to update the alias values in the schemas first):

Here are the table schemas for the Amazon Athena database <athena_schemas>. 

<athena_schemas>
  <athena_schema>
  CREATE EXTERNAL TABLE athena_db.customers (
    `Cust_Id` integer,
    `Customer` string,
    `Balance` integer,
    `Past_Due` integer,
    `Vip` string
  )
  ROW FORMAT DELIMITED 
  FIELDS TERMINATED BY ',' 
  LINES TERMINATED BY '\n'
  STORED AS TEXTFILE
  LOCATION 's3://athena-datasource-{alias}/';  
  </athena_schema>
  
  <athena_schema>
  CREATE EXTERNAL TABLE athena_db.procedures (
    `Procedure_ID` string,
    `Procedure` string,
    `Category` string,
    `Price` integer,
    `Duration` integer,

  SELECT * FROM athena_db.procedures WHERE insurance = 'yes' OR insurance = 'no';  
  </athena_example>
  
  <athena_example>
    SELECT * FROM athena_db.customers WHERE balance >= 0;
  </athena_example>
</athena_examples>
  • Here is a clip on configuring the requirements from above. adv prompt create gif

  • This prompt helps provide the agent an example of the table schema(s) used for the database, along with an example of how the Amazon Athena query should be formatted. Additionally, there is an option to use a custom parser Lambda function for more granular formatting.

  • Scroll to the bottom and select the Save and exit. Then, Save and exit one more time.

Step 5: Create an alias

  • At the top, select Save, then Prepare. After, select Save and exit. Then, scroll down to the Alias section and select Create. Choose a name of your liking, then create the alias. Make sure to copy and save your AliasID. Also, scroll to the top and save the Agent ID located in the Agent overview section. You will need this in step 7. Refer to the screenshots below.

Alias Agent ID

Create alias

Agent ID

Agent ARN2

Step 6: Testing the Setup

Testing the Bedrock Agent

  • In the test UI on the right, select Prepare. Then, enter prompts in the user interface to test your Bedrock agent.

Agent test

  • Example prompts for Action Groups:

    1. Show me all of the procedures in the imaging category that are insured.

    2. Show me all of the customers that are vip, and have a balance over 200 dollars.

    3. Return to me the number of procedures that are in the laboratory category.

    4. Get me data of all procedures that were not insured, with customer names.

Step 7: Setup and Run Streamlit App on EC2 (Optional)

  1. Obtain CF template to launch the streamlit app: Download the Cloudformation template from here. This template will be used to deploy an EC2 instance that has the Streamlit code to run the UI.

  2. Edit the app to update agent IDs:

    • Navigate to the EC2 instance management console. Under instances, you should see EC2-Streamlit-App. Select the checkbox next to it, then connect to it via EC2 Instance Connect.

    ec2 connect clip

  • If you see a message that says EC2 Instance Connect service IP addresses are not authorized, then you will need to re-deploy the template and select the correct CIDR range for the EC2 based on the region you are in. This will allow you to cannect to the EC2 instance via SSH. By default, it is the allowed CIDR range for us-west-2 region.
