Explanation:
Delta Lake, as part of the Databricks Lakehouse Platform, provides the ability to support both batch and streaming workloads. Delta Lake is a storage layer that brings ACID transactions to Apache Spark and big data workloads. It enables:
- Unified batch and streaming: Delta Lake tables can serve as both batch tables and streaming sources/sinks
- ACID transactions: Ensures data integrity with atomicity, consistency, isolation, and durability
- Schema enforcement and evolution: Prevents bad data from being written and allows schema changes
- Time travel: Enables data versioning and rollbacks
While other options may be features of the broader Databricks platform, the specific benefit of supporting both batch and streaming workloads is a core feature provided by Delta Lake itself.
