Data engineering services handle schema evolution by designing pipelines that are flexible and backward-compatible. Most large-scale pipelines use a schema-on-read approach, allowing new fields to be added without breaking ingestion.
Schema versioning, schema registries (for streaming data), and flexible file formats like Parquet and Avro help manage structural changes safely. Transformations are typically isolated in an ELT layer, where tools like dbt control how schema changes are applied downstream.
Automated validation and metadata-driven pipelines detect schema drift early, ensuring reliability at scale. This approach allows a data engineering company to adapt to changing data structures without disrupting analytics or production workloads.
