\n\n## Quickstart\n\nInstalling UStore is a breeze, and the usage is about as simple as a Python `dict`.\n\n```python\n$ pip install ukv\n$ python\n\nfrom ukv import umem\n\ndb = umem.DataBase()\ndb.main[42] = 'Hi'\n```\n\nWe have just create an in-memory embedded transactional database and added one entry in its `main` collection.\nWould you prefer that data on disk?\nChange one line.\n\n```python\nfrom ukv import rocksdb\n\ndb = rocksdb.DataBase('/","github_created_at":"2022-06-12T15:03:37+00:00","created_at":"2026-07-11T11:35:01.33174+00:00","updated_at":"2026-08-23T06:02:16.535058+00:00","categories":[{"slug":"data-retrieval","name":"Data & Retrieval","url":"https://www.graphcanon.com/categories/data-retrieval","markdown_url":"https://www.graphcanon.com/categories/data-retrieval.md","api_url":"https://www.graphcanon.com/api/graphcanon/categories/data-retrieval"}],"tags":[{"slug":"acid","name":"acid"},{"slug":"apache-arrow","name":"apache-arrow"},{"slug":"arrow","name":"arrow"},{"slug":"big-data","name":"big-data"},{"slug":"database","name":"database"},{"slug":"dataloader","name":"dataloader"},{"slug":"document-database","name":"document-database"},{"slug":"graph-database","name":"graph-database"}],"trust":{"provenance":{"is_fork":false,"github_id":502647695,"owner_type":"Organization","methodology":"github_public_v1","parent_repo":null,"near_duplicate_slugs":[]},"computed_at":"2026-08-23T06:02:15.801Z","maintenance":{"label":"Dormant","score":18,"methodology":"github_public_v1","releases_90d":0,"days_since_push":1086,"last_release_at":"2023-09-01T12:18:21Z","stars_delta_30d":0,"open_issues_delta_30d":0},"security_summary":{"status":"no_lockfile","scanner":null,"low_count":0,"high_count":0,"last_scan_at":"2026-07-11T11:35:02.532Z","medium_count":0,"scan_profile":"none","critical_count":0}},"capability_facts":{"scan":{"source":"repo_scan","observed_at":"2026-08-23T06:02:16.246Z"},"deploy":{"source":"dockerfile:Dockerfile","self_host":true,"observed_at":"2026-08-23T06:02:16.246Z","managed_saas":false},"languages":{"value":["c++","python"],"source":"github.language+pyproject.toml","observed_at":"2026-08-23T06:02:16.246Z"},"has_docker":{"value":true,"source":"dockerfile:Dockerfile","observed_at":"2026-08-23T06:02:16.246Z"},"license_spdx":{"value":"Apache-2.0","source":"github.license","observed_at":"2026-08-23T06:02:16.246Z"}},"decision_facts":{"hosting":null,"pricing":null,"requirements":null,"constraints":null,"when_to_use":["When you need ACID-compliant transactions in handling large volumes of multi-modal data","For applications needing performance improvements over MongoDB, Neo4J, and ElasticSearch","If your project requires a database with bindings for C++, Python, Java, or Go"],"when_not_to_use":["In environments where only traditional relational databases are allowed due to legacy constraints","When specific features of specialized databases like Neo4J (graph analytics) or ElasticSearch (full-text search) are critical and cannot be replaced by alternatives in UStore","If the project strictly requires database solutions under a license other than Apache-2.0"],"source":"enrich:decision_facts","observed_at":"2026-07-12T17:47:22.941Z"},"constraint_facets":null,"decision_summary":[{"label":"Adopt for","value":"UStore is a multi-modal database offering faster ACID transactions compared to traditional databases like MongoDB or Neo4J via NetworkX and Pandas interfaces."},{"label":"License detail","value":"Apache-2.0 license, offering permissive terms suitable for both open-source and commercial projects."}]}}
