In this post, we show how to capture the data quality metrics for data assets produced in Amazon Redshift. With Amazon DataZone, the data owner can directly import the technical metadata of a Redshift database table and views to the Amazon DataZone project’s inventory. As these data assets gets imported into Amazon DataZone, it bypasses the AWS Glue Data Catalog, creating a gap in data quality integration. This post proposes a solution to enrich the Amazon Redshift data asset with data quality scores and KPI metrics.

Poor data quality can lead to a variety of problems, including pipeline failures, incorrect reporting, and poor business decisions. For example, if data ingested from one of the systems contains a high number of duplicates, it can result in skewed data in the reporting system. To prevent such issues, data quality checks are integrated into […]

In this blog post, we explore how to use the SFTP Connector for AWS Glue from the AWS Marketplace to efficiently process data from Secure File Transfer Protocol (SFTP) servers into Amazon Simple Storage Service (Amazon S3), further empowering your data analytics and insights.

Amazon Redshift Advisor offers recommendations about optimizing your Redshift cluster performance and helps you save on operating costs. In this post, we show you how to use the ListRecommendations API to set up email notifications for Advisor recommendations on your Redshift cluster. These recommendations, such as identifying tables that should be vacuumed to sort the data or finding table columns that are candidates for compression, can help improve performance and save costs.

As businesses strive to make informed decisions, the amount of data being generated and required for analysis is growing exponentially. This trend is no exception for Dafiti, an ecommerce company that recognizes the importance of using data to drive strategic decision-making processes. With the ever-increasing volume of data available, Dafiti faces the challenge of effectively managing and extracting valuable insights from this vast pool of information to gain a competitive edge and make data-driven decisions that align with company business objectives. The growing need for storage space to maintain data from over 90 sources and the functionality available on the new Amazon Redshift node types, including managed storage, data sharing, and zero-ETL integrations, led us to migrate from DC2 to RA3 nodes. In this post, we share how we handled the migration process and provide further impressions of our experience.

In today’s landscape, data streams continuously from countless sources such as social media interactions to Internet of Things (IoT) device readings. This torrent of real-time information presents both a challenge and an opportunity for businesses. To harness the power of this data effectively, organizations need robust systems for ingesting, processing, and analyzing streaming data at […]

As builders, sometimes you want to dissect a customer experience, find problems, and figure out ways to make it better. That means going a layer down to mix and match primitives together to get more comprehensive features and more customization, flexibility, and freedom. In this post, we introduce Log Lake, a do-it-yourself data lake based on logs from CloudWatch and AWS CloudTrail.

In this blog post, we will show how to use Amazon OpenSearch Ingestion to deliver CloudWatch logs to OpenSearch Serverless in near real-time. We outline a mechanism to connect a Lambda subscription filter with OpenSearch Ingestion and deliver logs to OpenSearch Serverless without explicitly needing a separate subscription filter for it.
