Study Notes
AWS Glue Workflows and Data Orchestration
- AWS Glue Workflows are the most cost-effective way to orchestrate an ETL data pipeline that crawls data from Microsoft SQL Server, performs ETL, and loads data into an Amazon S3 bucket.
Real-Time Queries on Amazon Redshift
- Amazon Redshift Data API is the solution with the least operational overhead to run real-time queries from a web-based trading application that accesses financial data stored in Amazon Redshift.
Automated Orchestration for ETL Workflows
- AWS Step Functions are the solution with the least operational overhead to provide automated orchestration for ETL workflows that ingest data from operational databases to an Amazon S3-based data lake, using AWS Glue and Amazon EMR.
Data Deduplication in Legacy Application Migrations
- AWS Glue ETL job with FindMatches machine learning transform is the solution with the least operational overhead to identify and remove duplicate information from legacy application data being migrated to an Amazon S3-based data lake.
Time-Based Analytics in Analytics Solutions
- Amazon Managed Service for Apache Flink is the solution with the least operational overhead to analyze data that might contain duplicates, including time-based analytics over a window of up to 30 minutes, using multiple types of aggregations, in an analytics solution using Amazon S3 for data storage and Amazon Redshift for a data warehouse.
Upgrading Amazon EBS Storage
- Create new GP3 volumes, transfer data gradually, and replace existing GP2 volumes is the solution with the least operational overhead to prevent interruptions in EC2 instances during migration to upgraded storage.
Reading Data from S3 Objects
- Using S3 Select with a SQL SELECT statement is the solution with the least operational overhead to read data from S3 objects in Apache Parquet format and query only one column.
Automating Redshift Materialized View Refresh
- Using Apache Airflow is the solution with the least effort to automate refresh schedules for Amazon Redshift materialized views.
Data Pipeline Orchestration
- Requirement: Orchestrate a data pipeline with AWS Lambda and AWS Glue job.
- Goal: Minimize management overhead.
- Solution: AWS Step Functions workflow.
- Steps:
- Define a state machine.
- Configure the state machine to execute Lambda function first.
- Then, execute AWS Glue job.
- This approach offers the least management overhead by leveraging a fully managed service (AWS Step Functions) and simplifying the workflow definition.
