Technical Concepts Explained
Every question sits somewhere along one path that you design as a data engineer:
- Source
- Ingest
- Transform
- Store
- Serve
- Batch vs streaming
- Batch moves data in scheduled chunks. Streaming handles records continuously as they arrive.
- ETL vs ELT
- ETL transforms data before loading it. ELT loads first and transforms inside the destination.
- Data lake vs warehouse
- A lake keeps raw data in files, typically on Amazon S3. A warehouse such as Amazon Redshift stores structured data tuned for fast SQL.
- Partitioning
- Splitting data by a key such as date, so queries scan less data and cost less.
- Columnar formats
- Parquet and ORC store data by column, which speeds up analytics and reduces storage.
- Schema evolution
- Handling changes in fields over time without breaking your pipelines.
- Idempotency
- Running the same job twice gives the same result, which makes retries safe.
- Data catalog
- A record of what data exists and where it lives, such as the AWS Glue Data Catalog.
