AMAZON AWS POSTGRESQL IMPORTR HOW TO

We learned how to crawl SQL Server tables using AWS Glue in my last article. To keep the transformation complexity minimum so that we focus on the configuration of the ETL job, here a table is created that has identical schema to the CSV file as shown below.Ĭrawling AWS S3 files and AWS RDS SQL Server tables The schema can be different as well, in that case, we will have to perform a transformation for the source data to load into the target table. Once you have connected to the instance, create a table that matches the schema of the CSV file that we just created. Log on to the AWS RDS SQL Server database instance using the editor of your choice. This completes the creation of our source data setup.ĪWS RDS SQL Server database objects setup Once you have uploaded the file successfully, it would look as shown below. Once the file has been created, upload it to the newly created S3 bucket by clicking on the Upload button in the AWS S3 Bucket interface. In our case, we have a sample file named employees that has two fields and a few records as shown below. Create a sample CSV file as shown below and add some sample data to it. Provide a relevant name and create the bucket in the same region where you have hosted your AWS RDS SQL Server instance. From the Amazon S3 home page, click on the Create Bucket button to create a new AWS S3 bucket. Navigate to the AWS S3 home page, by typing S3 on the AWS Console home page and then open the selected service. Setting up an AWS S3 Bucket with sample data Do ensure, that you have the required permissions to manage an AWS S3 bucket as well as the SQL Server database instance. Even a SQL Server Express edition hosted on SQL Server instance will work. Amazon S3 would act as the source and the SQL Server database instance would act as the destination. For the ETL job that we would be developing in this article, we need a source and a target data repository. Once the instance is available, it would look as shown below. It’s assumed that an operational instance of AWS RDS SQL Server is already in place. In this article, we will explore the process of creating ETL jobs using AWS Glue to load data from Amazon S3 to an Amazon RDS SQL Server database instance. Often semi-structured data in the form of CSV, JSON, AVRO, Parquet and other file-formats hosted on S3 is loaded into Amazon RDS SQL Server database instances. AWS S3 is the primary storage layer for AWS Data Lake. One of the AWS services that provide ETL functionality is AWS Glue. Data is often load in and out of these instances using different types of ETL tools. Enterprises host production workloads on AWS RDS SQL Server instances on the cloud. Data is transported from source to destination data repositories using ETL jobs. This article explains how to develop ETL (Extract Transform Load) jobs using AWS Glue to load data from AWS S3 into AWS RDS SQL Server database objects.ĮTL is one of the widely-used methods for data integration in any enterprise IT landscape.
