Decision brief

Lance is an open lakehouse format built for multimodal AI, offering fast random access and vector index creation with extensive language compatibility.

Good fit when

Use Lance when you need fast random access to datasets formatted in a way that supports multimodal AI workloads.
Use if your project requires the ability to quickly convert Parquet files into Lance without significant changes to your codebase.

Avoid when

Do not use Lance if your application strictly depends on a specific format other than those compatible with it, such as HDF5 or non-supported SQL databases.
Avoid using Lance if real-time performance is critical for all operations and you do not require vector indexing capabilities.
