Since both SQS or SNS won't support a message size of 10MB, after each execution, you can push the 10MB data to AWS S3 where the bucket is configured with events to send a notification to SQS or SNS Topic. This pattern describes how to access on-premises Microsoft SQL Server database tables running on Microsoft Windows, from Microsoft SQL Server databases running on Amazon Elastic Compute Cloud (Amazon EC2) Windows or Linux instances by using linked servers. If the connection is created in the initialization code (outside the handler), it remains open till the TTL (idle timeout) and is closed by the DB server.

Idle waiting for a new request: It starts after returning the response of the previous request. I know I can use a REST interface on the on-prem app for the Lambda to make calls to, but I am wondering if it is possible to use a messaging system to integrate the on-prem resource with the AWS Lambdas (i.e., Lambda writes to a Kafka topic that the on-prem application can read from).

Routing tables attached to Subnet, Are Ec2 and Lambda launched in the same Subnet and using the same routing table ? So it is logical to cache heavy resources like open DB connections between calls instead of creating a new one with each request. By default, you can connect to a proxy with the same username and password that it uses to connect to the 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.

In the sample AWS Glue can also connect to a variety of on-premises JDBC data stores such as PostgreSQL, MySQL, Oracle, Microsoft SQL Server, and MariaDB. Add a rule to the security group used by the DB to allow inbound access from the lambda-sg to the DB port. There was small difference in setups between EC2 and lambda - where lambda were using NAT instead of IGM, however I reconfigured and it is still the same. drawback of this method is that you must expose the password to your function code, either by configuring it in a You can then run an SQL query over the partitioned Parquet data in the Athena Query Editor, as shown here. Created Triggers, Views, Synonyms and Roles to maintain integrity plan and database security. Secrets Manager to access database credentials. To avoid this situation, you can optimize the number of Apache Spark partitions and parallel JDBC connections that are opened during the job execution.
