Exam Tips for Domain 1
Know when to use Glue (batch ETL) vs Kinesis Firehose (near-real-time delivery) vs Kinesis Data Streams (real-time with custom consumers).

DMS with CDC enables continuous replication from source databases to AWS targets.
Convert data to columnar formats (Parquet, ORC) early in the pipeline for downstream query performance.
