Editorial take
Why it stands out
Delta Lake should be described as a lakehouse format and transaction layer, not as a generic database listing.

Tool profile
Open-source table format for building reliable lakehouse data platforms with ACID transactions, schema enforcement, and strong Spark ecosystem support.
Lakehouse architecture
Delta Lake is worth adding because it is one of the foundational lakehouse technologies in real-world analytics stacks. The official site positions it as an open-source project for building a Lakehouse architecture on top of data lakes, which is exactly the framing buyers need. Delta Lake matters not just as a file format, but as a practical reliability layer for large-scale data workflows, especially in ecosystems with deep Spark and Databricks alignment.
Its pricing posture is clean and project-led. Delta Lake is an open-source project under the Apache 2.0 license, and the official project site does not present a first-party public pricing page. That means the software itself is free, while actual spend comes from the compute engines, storage, orchestration, and managed platforms teams choose to run with it.
