Open Source Data Lakehouse: What It Means and Why Vendor Lock-In Is the Real Risk

Open data lakehouses distinguish between genuinely portable storage and table formats, such as Parquet, Iceberg, Delta, or ORC, and the often proprietary platform layers that govern catalog access, security policies, orchestration, and performance tuning. Although open formats allow other engines to read data and metadata, organizations may still face substantial vendor lock-in when catalogs are inaccessible, governance rules cannot be exported, jobs depend on proprietary runtimes, or engine-specific optimizations must be rebuilt. The most significant exit costs are therefore typically measured in engineering time for rewrites, retesting, retraining, and parallel operations rather than data-transfer fees, which EU Data Act rules are set to eliminate for covered switching charges by January 2027. Enterprises evaluating lakehouse platforms are encouraged to assess portability by asking vendors to document how data, catalog metadata, governance policies, workloads, and tuning would migrate to alternative tools, and to provide evidence from customers that have successfully exited the platform.
