Build an end to end, automated inventory forecasting capability with AWS Lake Formation and Amazon Forecast
This post demonstrates how you can automate the data extraction, transformation, and use of Forecast for the use case of a retailer that requires recurring replenishment of inventory. You achieve this by using AWS Lake Formation to build a secure data lake and ingest data into it, orchestrate the data transformation using an AWS Glue workflow, and visualize the forecast results in Amazon QuickSight.
Build an AWS Well-Architected environment with the Analytics Lens
Building a modern data platform on AWS enables you to collect data of all types, store it in a central, secure repository, and analyze it with purpose-built tools. Yet you may be unsure of how to get started and the impact of certain design decisions. To address the need to provide advice tailored to specific technology and application domains, AWS added the concept of well-architected lenses 2017. AWS now is happy to announce the Analytics Lens for the AWS Well-Architected Framework. This post provides an introduction of its purpose, topics covered, common scenarios, and services included.
Optimize memory management in AWS Glue
In this post, we discuss a number of techniques to enable efficient memory management for Apache Spark applications when reading data from Amazon S3 and compatible databases using a JDBC connector. We describe how Glue ETL jobs can utilize the partitioning information available from AWS Glue Data Catalog to prune large datasets, manage large number of small files, and use JDBC optimizations for partitioned reads and batch record fetch from databases. You can use some or all of these techniques to help ensure your ETL jobs perform well.
Build an automatic data profiling and reporting solution with Amazon EMR, AWS Glue, and Amazon QuickSight
This post demonstrates how to extend the metadata contained in the Data Catalog with profiling information calculated with an Apache Spark application based on the Amazon Deequ library running on an EMR cluster. You can query the Data Catalog using the AWS CLI. You can also build a reporting system with Athena and Amazon QuickSight to query and visualize the data stored in Amazon S3.
