How do Apache Iceberg, Delta Lake, and Apache Hudi compare as open table formats?

Apache Iceberg has emerged as the most broadly adopted open table format, supported by Snowflake, BigQuery, Redshift, Flink, and Spark. Delta Lake has the deepest Databricks and Spark integration. Hudi specializes in record-level upserts for streaming use cases like CDC-based data lake updates from transactional databases.

What governance capabilities are essential in a data lakehouse platform?

Enterprise lakehouse governance requires: unified data catalog with lineage, column-level access control, row-level security, attribute-based access control (ABAC), data classification and masking for PII/sensitive data, audit logging, and cross-engine consistency of policies across Spark, SQL, and ML frameworks.

How does the lakehouse architecture reduce data engineering complexity versus traditional warehouse + data lake architectures?

Traditional architectures required maintaining separate ETL pipelines to load data from the data lake (raw) into the data warehouse (processed). The lakehouse eliminates the warehouse tier by enabling direct SQL querying on object storage via open table formats, reducing data duplication, pipeline complexity, and the cost of maintaining two parallel storage systems.
