Combine with OpenSearch Serverless

The Vector Engine for Amazon OpenSearch Serverless is an on-demand serverless configuration for OpenSearch Service. As a result of it’s serverless, it removes the operational complexities of provisioning, configuring, and tuning your OpenSearch clusters. With OpenSearch Serverless, you possibly can search and analyze a big quantity of information with out having to fret concerning the underlying infrastructure and knowledge administration.

The next diagram illustrates the OpenSearch Serverless structure. OpenSearch Serverless compute capability for knowledge ingestion, looking out, and querying is measured in OpenSearch Compute Items (OCUs).

The vector search assortment kind in OpenSearch Serverless gives a similarity search functionality that’s scalable and excessive performing. This makes it a well-liked choice for a vector database when utilizing Amazon Bedrock Data Bases, as a result of it makes it easy to construct trendy machine studying (ML) augmented search experiences and generative AI functions with out having to handle the underlying vector database infrastructure. Use circumstances for OpenSearch Serverless vector search collections embody picture searches, doc searches, music retrieval, product suggestions, video searches, location-based searches, fraud detection, and anomaly detection. The vector engine gives distance metrics corresponding to Euclidean distance, cosine similarity, and dot product similarity. You may retailer fields with numerous knowledge sorts for metadata, corresponding to numbers, Booleans, dates, key phrases, and geopoints. You can even retailer fields with textual content for descriptive info so as to add extra context to saved vectors. Collocating the information sorts reduces complexity, will increase maintainability, and avoids knowledge duplication, model compatibility challenges, and licensing points.

The next code snippets arrange an OpenSearch Serverless vector database and combine it with a information base in Amazon Bedrock:

1.  Create an OpenSearch Serverless vector assortment.

   # create safety, community and knowledge entry insurance policies inside OSS
   encryption_policy, network_policy, access_policy = create_policies_in_oss(vector_store_name=oss_vector_store_name,
   aoss_client=aoss_client,
   bedrock_kb_execution_role_arn=bedrock_kb_execution_role_arn)
   
   # Create OpenSearch Serverless Vector Assortment
   assortment = aoss_client.create_collection(identify=oss_vector_store_name,kind="VECTORSEARCH")
   
   # Get the OpenSearch serverless assortment URL
   collection_id = assortment['createCollectionDetail']['id']
   host = collection_id + '.' + region_name + '.aoss.amazonaws.com'
   print(host)
   
   # look ahead to assortment creation
   # This may take couple of minutes to complete
   response = aoss_client.batch_get_collection(names=[oss_vector_store_name])
   # Periodically test assortment standing
   whereas (response['collectionDetails'][0]['status']) == 'CREATING':
   print('Creating assortment...')
   time.sleep(30)
   response = aoss_client.batch_get_collection(names=[oss_vector_store_name])
   print('nCollection efficiently created:')
   
   
   # create opensearch serverless entry coverage and connect it to Bedrock execution position
   attempt:
   create_oss_policy_attach_bedrock_execution_role(collection_id=collection_id,
   bedrock_kb_execution_role=bedrock_kb_execution_role)
   # It could actually take as much as a minute for knowledge entry guidelines to be enforced
   time.sleep(60)
   besides Exception as e:
   print("Coverage already exists")
   pp.pprint(e)

2. Create an index within the assortment; this index can be managed by Amazon Bedrock Data Bases:

   body_json = {
      "settings": {
         "index.knn": "true",
          "number_of_shards": 1,
          "knn.algo_param.ef_search": 512,

            },
            "text-metadata": {
               "kind": "textual content"         }
         }
      }
   }
   
   # Construct the OpenSearch consumer
   oss_client = OpenSearch(
       hosts=[{'host': host, 'port': 443}],
       http_auth=awsauth,
       use_ssl=True,
       verify_certs=True,
       connection_class=RequestsHttpConnection,
       timeout=300
   )
   
   # Create index
   attempt:
       response = oss_client.indices.create(index=oss_index_name, physique=json.dumps(body_json))
       print('Creating index:')
       # index creation can take as much as a minute
       time.sleep(60)
       print('Index Creation Accomplished:')
   besides RequestError as e:
       # you possibly can delete the index if its already exists
       # oss_client.indices.delete(index=oss_index_name)
       print(f'Error whereas making an attempt to create the index, with error {e.error}nyou might unmark the delete above to delete, and recreate the index')

3. Create a information base in Amazon Bedrock pointing to the OpenSearch Serverless vector assortment and index:

   opensearchServerlessConfiguration = {
               "collectionArn": assortment["createCollectionDetail"]['arn'],
               "vectorIndexName": oss_index_name,
               "fieldMapping": {

                   "metadataField": "text-metadata"
               }
           }
   
   # The embedding mannequin utilized by Bedrock to embed ingested paperwork, and realtime prompts
   embeddingModelArn = f"arn:aws:bedrock:{region_name}::foundation-model/amazon.titan-embed-text-v2:0"
   
   identify = f"kb-os-shareholder-letter-{suffix}"
   description = "Amazon shareholder letter information base."
   roleArn = bedrock_kb_execution_role_arn
   
   # Create a KnowledgeBase
   from retrying import retry
   
   @retry(wait_random_min=1000, wait_random_max=2000,stop_max_attempt_number=7)
   def create_knowledge_base_func():
       create_kb_response = bedrock_agent_client.create_knowledge_base(
           identify = identify,
           description = description,
           roleArn = roleArn,
           knowledgeBaseConfiguration = {
               "kind": "VECTOR",
               "vectorKnowledgeBaseConfiguration": {
                   "embeddingModelArn": embeddingModelArn
               }
           },
           storageConfiguration = {
               "kind": "OPENSEARCH_SERVERLESS",
               "opensearchServerlessConfiguration":opensearchServerlessConfiguration
           }
       )
       return create_kb_response["knowledgeBase"]
   
   
   attempt:
       kb = create_knowledge_base_func()
   besides Exception as err:
       print(f"{err=}, {kind(err)=}")
       
   # Get KnowledgeBase 
   get_kb_response = bedrock_agent_client.get_knowledge_base(knowledgeBaseId = kb['knowledgeBaseId'])
   
   print(f'OpenSearch Data Response: {get_kb_response}')

4. Create a knowledge supply for the information base:

   # Ingest technique - The right way to ingest knowledge from the information supply
   chunkingStrategyConfiguration = {
       "chunkingStrategy": "FIXED_SIZE",
       "fixedSizeChunkingConfiguration": {
           "maxTokens": 512,
           "overlapPercentage": 20
       }

   # The info supply to ingest paperwork from, into the OpenSearch serverless information base index
   s3Configuration = {
       "bucketArn": f"arn:aws:s3:::{data_s3_bucket}",
       "inclusionPrefixes": [f"{data_s3_prefix}"] # you should utilize this if you wish to create a KB utilizing knowledge inside s3 prefixes.
       }
   # Create a DataSource in KnowledgeBase 
   create_ds_response = bedrock_agent_client.create_data_source(
       identify = f'{identify}-{bucket_name}',
       description = description,
       knowledgeBaseId = kb['knowledgeBaseId'],
       dataSourceConfiguration = {

Combine with Aurora pgvector

Aurora gives pgvector integration, which is an open supply extension for PostgreSQL that provides the power to retailer and search over ML-generated vector embeddings. This lets you use Aurora for generative AI RAG-based use circumstances by storing vectors with the remainder of the information. The next diagram illustrates the pattern structure.

Use circumstances for Aurora pgvector embody functions which have necessities for ACID compliance, point-in-time restoration, joins, and extra. The next is a pattern code snippet to configure Aurora along with your information base in Amazon Bedrock:

1. Create an Aurora DB occasion (this code creates a managed DB occasion, however you possibly can create a serverless occasion as effectively). Determine the safety group ID and subnet IDs on your VPC earlier than working the next step and supply the suitable values within the vpc_security_group_ids and SubnetIds variables:

   # Outline database occasion parameters
   db_instance_identifier = aurora_vector_db_instance
   db_cluster_identifier = aurora_vector_db_cluster
   engine="aurora-postgresql"
   db_name = aurora_database_name
   db_instance_class="db.r6g.2xlarge"
   master_username="postgres"
   # Get Safety Group Id(s), for replicating Blogpost steps it may be one related to Default VPC
   vpc_security_group_ids = ['sg-XXXXXXX']
   subnet_group_name="vectordbsubnetgroup"
   
   response = rds.create_db_subnet_group(
       DBSubnetGroupName=subnet_group_name,
       DBSubnetGroupDescription='Subnet Group for Blogpost Aurora PostgreSql Database Cluster',
       # Get Subnet IDs, for replicating Blogpost steps it may be one related to Default VPC 
       SubnetIds=[
           'subnet-XXXXXXX',
           'subnet-XXXXXXX',
           'subnet-XXXXXXX',
           'subnet-XXXXXXX',
           'subnet-XXXXXXX',
           'subnet-XXXXXXX'
       ]
   )
   
   # Create the Aurora cluster
   response = rds.create_db_cluster(
       DBClusterIdentifier=db_cluster_identifier,
       Engine=engine,
       MasterUsername=master_username,
       ManageMasterUserPassword=True,
       DBSubnetGroupName=subnet_group_name,
       VpcSecurityGroupIds=vpc_security_group_ids,
       DatabaseName=db_name
   )
   
   # Create the Aurora occasion
   response = rds.create_db_instance(
       DBInstanceIdentifier=db_instance_identifier,
       DBInstanceClass=db_instance_class,
       Engine=engine,
       DBClusterIdentifier=db_cluster_identifier
   )

2. On the Amazon RDS console, affirm the Aurora database standing reveals as Accessible.
   
3. Create the vector extension, schema, and vector desk within the Aurora database:

   ##Get Amazon Aurora Database Secret Supervisor ARN created internally whereas creating DB Cluster and Database Cluster ARN
   
   describe_db_clusters_response = rds.describe_db_clusters(
       DBClusterIdentifier=db_cluster_identifier,
       IncludeShared=False
   )
   
   aurora_db_secret_arn = describe_db_clusters_response['DBClusters'][0]['MasterUserSecret']['SecretArn']
   db_cluster_arn = describe_db_clusters_response['DBClusters'][0]['DBClusterArn']
   
   # Allow HTTP Endpoint for Amazon Aurora Database occasion
   response = rds.enable_http_endpoint(
       ResourceArn=db_cluster_arn
   )
   
   # Create Vector Extension in Aurora PostgreSQL Database which can be utilized in desk creation
   vector_extension_create_response = rds_data_client.execute_statement(
       resourceArn=db_cluster_arn,
       secretArn=aurora_db_secret_arn,
       sql="CREATE EXTENSION IF NOT EXISTS vector",
       database=db_name
   )
   
   # Create Schema in Aurora PostgreSQL database
   schema_create_response = rds_data_client.execute_statement(
       resourceArn=db_cluster_arn,
       secretArn=aurora_db_secret_arn,
       sql="CREATE SCHEMA IF NOT EXISTS bedrock_integration",
       database=db_name
   )
   
   # Create Desk which retailer vector embedding equivalent to Shareholder letters
   table_create_response = rds_data_client.execute_statement(
       resourceArn=db_cluster_arn,
       secretArn=aurora_db_secret_arn,
       sql="CREATE TABLE IF NOT EXISTS bedrock_integration.share_holder_letter_kb(id uuid PRIMARY KEY, embedding vector(1024), chunks textual content, metadata json, firm varchar(100), document_type varchar(100), 12 months int)",
       database=db_name
   )
   
   # Test the standing of queries
   vector_extension_create_status="Success" if vector_extension_create_response['ResponseMetadata']['HTTPStatusCode'] == 200 else 'Fail'
   schema_create_status="Success" if schema_create_response['ResponseMetadata']['HTTPStatusCode'] == 200 else 'Fail'
   table_create_response="Success" if table_create_response['ResponseMetadata']['HTTPStatusCode'] == 200 else 'Fail'
   
   # Print the standing of queries
   print(f"Create Vector Extension Standing: {vector_extension_create_status}")
   print(f"Create Schema Standing: {schema_create_status}")
   print(f"Create Desk Standing: {table_create_response}")

4. Create a information base in Amazon Bedrock pointing to the Aurora database and desk:

   # Hooked up RDS associated permissions to the Bedrock Knowledgebase position
   
   create_rds_policy_attach_bedrock_execution_role(db_cluster_arn, aurora_db_secret_arn, bedrock_kb_execution_role)
   
   # Outline RDS Configuration for Data bases
   rdsConfiguration = {
               'credentialsSecretArn': aurora_db_secret_arn,
               'databaseName': db_name,

                   'vectorField': 'embedding'
               },
               'resourceArn': db_cluster_arn,
               'tableName': 'bedrock_integration.share_holder_letter_kb'
           }
   
   
   # The embedding mannequin utilized by Bedrock to embed ingested paperwork, and realtime prompts
   embeddingModelArn = f"arn:aws:bedrock:{region_name}::foundation-model/amazon.titan-embed-text-v2:0"
   
   identify = f"kb-aurora-shareholder-letter-{suffix}"
   description = "Amazon shareholder letter Aurora PG Vector information base."
   roleArn = bedrock_kb_execution_role_arn
   
   # Create a KnowledgeBase
   from retrying import retry
   
   @retry(wait_random_min=1000, wait_random_max=2000,stop_max_attempt_number=7)
   def create_knowledge_base_func():
       create_rds_kb_response = bedrock_agent_client.create_knowledge_base(
           identify = identify,
           description = description,
           roleArn = roleArn,
           knowledgeBaseConfiguration = {
