It provides two main interfaces: PyMPHF for building and querying a minimal perfect hash function, and BBHashTable for associating arbitrary values with hashes and retrieving them later. The package is designed primarily for bioinformatics workflows involving k-mer hashing, where you need to map large collections of hash values to compact integer identifiers or associated metadata.\n\nThe core use case is storing and querying relationships between hashes generated by tools like khmer or sourmash\u2014for example, mapping k-mer hashes to De Bruijn graph node IDs. BBHashTable extends the basic MPHF by supporting lookups on hashes that were not part of the original construction, returning None for missing keys. Both modules support save/load to disk for persistence.","worth_installing":"Yes, with conditions. Install if you need minimal perfect hash functions for 64-bit hashes in a bioinformatics or k-mer-heavy workflow and can tolerate Cython compilation. The package is actively maintained and has no known vulnerabilities, but verify the unclear license status before use in proprietary contexts. High install friction and Python >=3.11 requirement may limit adoption in legacy environments."},"id":"bbhash","links":{"html":"https://skillfed.io/packages/bbhash","md":"https://skillfed.io/packages/bbhash.md","pypi":"https://pypi.org/project/bbhash/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-10-26","license_spdx":null,"license_treatment":"unclear","name":"bbhash","python_support":"supports_current","summary":"A Python wrapper for the BBHash Minimal Perfect Hash Function"},"popularity":{"monthly_downloads":87699,"position":13775,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.6.0"}
