Yi Hu's Proposals and Results:Case Study:Data warehouse and ETL solution for media companySince Yi Hu joined ThisisYiHu in Greater New York City Area in 2018, she has been working on a data warehouse and ETL solution for a Fortune 500 media company. In their previous roles at this company, Yi Hu has expertise in architecture, implement and maintain end-to-end data processing solutions, as well as previously working on a data cleaning and Spark deployed data analysis solution.The team at the media company was looking for a scalable data warehousing solution that could join the usage data with the content meta data to allow business analysts perform aggregate reporting as well as ad hoc analytics when required. As part of their development, they used Amazon Redshift, a fully managed data warehouse, to deliver the performance they required.The whole process can be automated to ingest new data into Redshift on a daily basis, which reduces the time required to process data. The solution involves the following key milestones:1. Use Ansible and CloudFormation, provision and deploy a SFTP server that securely accepts daily log files from the third-party analytics vendor and automatically moves the log files to S3.2. Use Spark (PySpark) and Luigi on an Amazon EMR cluster to transform and cleanse the log data. Data behind the API is loaded in parallel and cleansed. The cleaned data is compressed and saved to S3.3. Redshift loads the cleaned data in parallel into tables. All tables are created with optimal compression type, distribution style, distribution keys, and sort keys for faster query performance.4. Use AWS Step Functions and AWS Lambda together orchestrate and automate the AWS resources needed to ingest new data into Redshift on a daily basis. Errors are logged in CloudWatch and employees are notified through SNS when error occurs.5. The automated data processing solution is deployed with CloudFormation so that all AWS resources can be easily managed and updated.
