About h5db

This extension provides table functions for reading data and metadata from HDF5 files.

Features include:

• h5_tree() table function to list groups and datasets in a file.
• h5_read() table function to read datasets.
• h5_attributes() table function to access attributes.
• Multiple datasets: Read and combine multiple datasets in a single query.
• Multi-dimensional arrays: Support for 1D to 4D datasets.
• Projection pushdown: Reads only the datasets that are actually needed.
• Index column: Optionally adds an index column that supports pushdown of constant range filters (>, <=, BETWEEN, etc.) for efficient selective reads.
• Reads datasets that are larger than memory.
• Remote dataset reads via the httpfs extension.
