Vectors are held quantised and compared by a brute-force dot product, which the README reports at about 20μs per comparison, or some 50,000 vectors a second. Quantisation cuts a 1536-dimension vector from 12,288 bytes to 192, so 1GB holds 5.5 million quantised vectors against 87,000 unquantised ones. The library is self-contained for that core; generating the embeddings is a separate job, and for it the README points at the [Microsoft AI SDK for SAP](artifact:microsoft-aisdkforsapabap), which it calls the OpenAI ABAP SDK."},"links":{"repo":"https://github.com/oisee/zvdb"},"type_properties":{"placement":{"value":"in-host","sources":[{"url":"https://github.com/oisee/zvdb","title":"oisee/zvdb — README","checked":"2026-10-19","quote":"a Vector Database developed entirely in ABAP, designed to offer an independent solution without relying on external vector databases"}]},"distribution":{"value":["abapgit"],"sources":[{"url":"https://github.com/oisee/zvdb","title":"oisee/zvdb — README, Installation","checked":"2026-10-19","quote":"Install this repository using [abapGit](https://github.com/abapGit/abapGit#abapgit)."}]}},"identity":{"license":"MIT"},"maintainers":["actor:oisee"],"source_available":true,"provides":[{"capability":"capability:retrieval-augmented-generation","what_it_does":"Stores and searches document-chunk embeddings as quantised vectors, entirely in ABAP, and assembles the matching chunks into a prompt for retrieval-augmented generation.","sources":[{"url":"https://github.com/oisee/zvdb","title":"oisee/zvdb — README","checked":"2026-10-19","quote":"The ABAP Vector Search Library is a Vector Database developed entirely in ABAP, designed to offer an independent solution without relying on external vector databases."},{"url":"https://github.com/oisee/zvdb","title":"oisee/zvdb — README","checked":"2026-10-19","quote":"RAG is the technique that is powering the “chat with your documents” scenario:\n - Slice documents into chunks\n - Inject semantically relevant chunks into the Prompt:"}]}],"requires":[{"ref":"artifact:abapgit-abapgit","requirement":"required","basis":"binding","for":"Installs the repository into the ABAP system; the README gives [abapGit](artifact:abapgit-abapgit) as the install method.","sources":[{"url":"https://github.com/oisee/zvdb","title":"oisee/zvdb — README, Installation","checked":"2026-10-19","quote":"Install this repository using [abapGit](https://github.com/abapGit/abapGit#abapgit)."}]}],"drafted_with_ai":true,"provenance":{"discovered_via":[{"source":"source:curator"}],"first_seen":"2026-09-14"},"contributors":["actor:larshp","actor:oisee"]},"effective_normative_relations":[],"readings":{"liveness":[{"label":"Maintenance","tier":"unknown","evidence":"no release data"},{"label":"Continuity","tier":"fair","evidence":"2 contributors"},{"label":"Repository","tier":"fair","evidence":"pushed 2025-09, not archived"}],"compatibility":[{"label":"Declared for","tier":"fair","evidence":"SAP_BASIS 755 and up, in its abaplint config: not 750 (SAP Business Suite 7 on SAP NetWeaver 7.50, maintained to 2027-12)"},{"label":"Survived majors","tier":"unknown","evidence":"not read on ABAP: its lines run side by side"},{"label":"Maintainer's CI","tier":"fair","evidence":"no CI configured"}],"practice":[{"label":"Tests","tier":"poor","evidence":"none found in the tree"},{"label":"Docs","tier":"good","evidence":"README 6 KB"},{"label":"Changelog","tier":"fair","evidence":"none in the repo"}],"reach":[{"value":null,"unit":"installs/week"},{"value":49,"unit":"watching"}]},"signals":{"crawled_at":"2026-10-25","npm":"not published under this name","stars":49,"forks":9,"open_issues":1,"archived":false,"pushed_at":"2025-09-14","license_spdx":"MIT","org_owned":false,"default_branch":"main","created_at":"2023-11-19T21:22:14Z","open_prs":0,"tree_truncated":false,"test_files":0,"workflows":0,"other_ci":false,"readme_bytes":5694,"docs_files":0,"changelog":false,"license_file":true,"dts_files":0,"first_commit":"2023-11-19","last_commit":"2025-09-14","commits":43,"contributors":2,"readme_path":"README.md","readme_sha":"6201b929edc0426e77e89e909769a7d1583b8407","repo_read":"2026-10-25","abap_syntax":{"repo":"oisee/zvdb","file":"abaplint.jsonc","url":"https://github.com/oisee/zvdb/blob/HEAD/abaplint.jsonc","version":"v755","floor":"755","checked":"2026-10-26"}},"edges":{"maintainers":[{"ref":"actor:oisee","name":"Alice V.","json":"/actors/oisee.json"}],"contributors":[{"ref":"actor:oisee","name":"Alice V.","json":"/actors/oisee.json"},{"ref":"actor:larshp","name":"Lars Hvam","json":"/actors/larshp.json"}],"explained_by":[],"alternative_to_this":[],"needed_by":[],"available_via":[],"parts":[],"add_ons":[],"answered_through_parts":[]}}
