The new connections will keep accumulating and can cause DB server extra resources consumption or connections be rejected if the server reaches the maximum connections limit. All rights reserved. AWS Lambda Connection Pooling Conclusion Lambda functions are stateless and asynchronous, and by using the database connection pool, you will be able to add a state to it. So it is logical to cache heavy resources like open DB connections between calls instead of creating a new one with each request. You need to review the ACLs of the on-premise firewall. AWS Glue then creates ENIs in the VPC/subnet and associate security groups as defined with only one JDBC connection.

Next, create another ETL job with the name cfs_onprem_postgres_to_s3_parquet. So if you define the Database connection outside the handler function it will be shared among the invocations of Lambda functions. Optionally, you can enable Job bookmark for an ETL job. Set up another crawler that points to the PostgreSQL database table and creates a table metadata in the AWS Glue Data Catalog as a data source. Another option is to implement a DNS forwarder in your VPC and set up hybrid DNS resolution to resolve using both on-premises DNS servers and the VPC DNS resolver.

The Lambda function will contain the AWS packages for the selected platform by default, so you don't need to include boto3 for example in your package if you are using python. Choose the VPC, private subnet, and the security group. The EC2 and Lambda function are in same VPC. It then tries to access both JDBC data stores over the network using the same set of ENIs. By default, the security group allows all outbound traffic and is sufficient for AWS Glue requirements. aws_lambda_policy_statement. Also, this works well for an AWS Glue ETL job that is set up with a single JDBC connection. tn=telnetlib.Telnet('
