Database indexes (keys) never need to be defragmented. Speed of insert/update/remove operations doesn't change during the time.\n- Ability to access Key/Value pair of a table by physical link, that can economize time for joining necessary data structures.\n- No limits for database size (except \"long\" size for each table and physical resources constraints).\n- Low memory and phys","github_created_at":"2013-08-12T07:34:47+00:00","created_at":"2026-07-11T11:27:56.686536+00:00","updated_at":"2026-08-22T00:01:08.156804+00:00","categories":[{"slug":"vector-databases","name":"Vector Databases","url":"https://www.graphcanon.com/categories/vector-databases","markdown_url":"https://www.graphcanon.com/categories/vector-databases.md","api_url":"https://www.graphcanon.com/api/graphcanon/categories/vector-databases"}],"tags":[{"slug":"acid","name":"acid"},{"slug":"c-sharp","name":"c-sharp"},{"slug":"clustering","name":"clustering"},{"slug":"database","name":"database"},{"slug":"dotnet","name":"dotnet"},{"slug":"embedded","name":"embedded"},{"slug":"key","name":"key"},{"slug":"nosql","name":"nosql"}],"trust":{"provenance":{"is_fork":false,"github_id":12050336,"owner_type":"User","methodology":"github_public_v1","parent_repo":null,"near_duplicate_slugs":[]},"computed_at":"2026-08-22T00:01:07.431Z","maintenance":{"label":"Very active","score":96,"methodology":"github_public_v1","releases_90d":1,"days_since_push":0,"last_release_at":"2026-06-03T17:35:27Z","stars_delta_30d":1,"open_issues_delta_30d":0},"security_summary":{"status":"no_lockfile","scanner":null,"low_count":0,"high_count":0,"last_scan_at":"2026-07-11T11:27:57.775Z","medium_count":0,"scan_profile":"none","critical_count":0}},"capability_facts":{"scan":{"source":"repo_scan","observed_at":"2026-08-22T00:01:07.896Z"},"languages":{"value":["c#"],"source":"github.language","observed_at":"2026-08-22T00:01:07.896Z"},"license_spdx":{"value":"BSD-2-Clause","source":"github.license","observed_at":"2026-08-22T00:01:07.896Z"}},"decision_facts":{"hosting":null,"pricing":{"model":"freemium","summary":"The BSD-2-Clause license under which DBreeze is released allows free usage, but there may be options for paid support or enhanced services not detailed here."},"requirements":null,"constraints":{"pricing_model":"freemium"},"when_to_use":["When developing applications in the C# .NET environment requiring robust, transactional (ACID) support.","For scenarios where both efficient text and semantic searches need to be integrated within a single database solution.","To leverage pre-built object store embedded features without needing additional integration efforts or third-party service connections."],"when_not_to_use":["If the project demands real-time scalability and distribution capabilities beyond what an embedded database can offer","In cases where Python, Java, or other non-.NET languages are preferred or required for development.","For environments that need a wider range of external connectivity as DBreeze specializes in embedded use."],"source":"enrich:decision_facts","observed_at":"2026-07-15T09:55:20.991Z"},"constraint_facets":{"pricing_model":"freemium"},"decision_summary":[{"label":"Pricing","value":"freemium - The BSD-2-Clause license under which DBreeze is released allows free usage, but there may be options for paid support or enhanced services not detailed here."},{"label":"Adopt for","value":"DBreeze is an ACID-compliant C# .NET database management system that supports key-value storage and offers advanced search features alongside vector layer capabilities."},{"label":"License detail","value":"BSD-2-Clause license makes it suitable for commercial and open-source applications without constraints on distribution"}]}}
