Vɛkta Database ƒe Nusrɔ̃ɖoɖo Kple Teknikal Numeɖeɖe
Agbalẽ sia nye numeɖeɖe kple nusrɔ̃ɖoɖo tso vɛkta database ƒe dodokpɔ me. Eɖe nu tso vɛkta database ƒe gɔmeɖeɖe vevitɔwo, teknikal susuwo, tiatiaɖoɖo kple dɔwɔƒe siwo me wozãna ɖo.
1. Gɔmeɖeɖe Vevitɔ
- Gɔmeɖeɖe: Vɛkta database nye database si wɔ dɔ ɖe vɛkta siwo le dzɔdzɔme me ƒe ɖoɖo kple xɔxɔ ŋu. Eƒe ŋusẽ vevitɔ nye ANN (Approximate Nearest Neighbor) diɖi, si na wòate ŋu akpɔ vɛkta siwo sɔ gbɔe kple vɛkta si wòdi le vɛkta gã aɖe me.
- Vovototo vevitɔ kple database bubuwo:
- Database bubuwo (abe MySQL): Wɔa dɔ nyuie le nu si pɛ pɛpɛpɛ diɖi me.
- Vɛkta database: Wɔa dɔ nyuie le gɔmesese sɔsɔ diɖi me. Eya wɔna esime wòbu vɛkta ƒe didime le dzɔdzɔme si me wole hena nu siwo sɔ gbɔe ƒe sɔsɔ.
2. Nuɖeɲa: Nu ka ta wòhiã be vɛkta database tɔxɛ aɖe nanɔ?
Database bubuwo (abe MySQL, PostgreSQL) ƒe B-tree index wɔa dɔ ɖe nu si pɛ pɛpɛpɛ diɖi ŋu, eye menyo na vɛkta siwo le dzɔdzɔme me ƒe sɔsɔ diɖi o. Nu si wɔna le vɛkta gãwo ŋu la, eƒe dɔwɔwɔ mebɔ o. Vɛkta database trɔna kple index algorithm tɔxɛwo hena ɖoɖo na henahe vevitɔ sia.
3. Index Algorithm Vevitɔwo
Agbalẽ la ɖe nu tso index algorithm vevitɔ eve siwo wozãna la ŋu, siwo nye dodokpɔ ƒe nublanu hã:
- HNSW: Ewɔa dɔ kple alɔdzedze si le dzɔdzɔme geɖe me, eƒe diɖi ƒe duɖiɖi kaba eye wònyo, gake index ƒe tɔtrɔ me la, eƒe ŋkuɖodzikpɔkpɔ sɔ gbɔe. Enyo na teƒe siwo wòhiã be woatrɔ gbɔe kple duɖiɖi kaba.
- IVF: Ewɔa dɔ kple susu si nye akpawo me, eye wòma vɛktawo ɖe akpa vovovowo me hena diɖi. Eƒe ŋkuɖodzikpɔkpɔ mede asi o, eye wònyo na vɛkta siwo sɔ gbɔe ŋutɔ. Gake eƒe nuteƒewɔwɔ mede HNSW ƒe nuteƒewɔwɔ o.
4. Vɛkta Database ƒe Ŋusẽ Vevitɔwo
Vɛkta database si wɔ dɔ le dɔwɔƒe me la, ehiã be wòanɔ ANN diɖi godoo, ke hã wòanɔ nu vevitɔ siawo ŋu:
- Metadata ƒe tɔtrɔ: Wɔa dɔ be wòate ŋu atsɔ nu siwo wòdi la aɖo ɖe diɖi me, abe afɔɖeɖe si le dɔwɔƒe alo ɣeyiɣi me.
- Tɔtrɔ le ɣeyiɣi me: Wɔa dɔ be wòate ŋu atsɔ nu yeye akpe, atrɔ alo atutu nu, eye mawɔ index la katã o.
- Keywords ƒe diɖi kple vɛkta diɖi ƒe ƒuƒoƒo: Wɔa dɔ be wòate ŋu aƒo vɛkta diɖi kple BM25 keywords diɖi ɖeka, hena diɖi si le alɔdzedze geɖe me, si na wòate ŋu akpɔ nu siwo pɛ pɛpɛpɛ kple gɔmesese sɔsɔ.
5. Tiatiaɖoɖo Kple Nudzɔdzɔwo ƒe Sɔsɔ
Agbalẽ la ɖe nu tso vɛkta ƒe sɔxɔxɔ, dɔwɔwɔ ƒe alɔdzedze, kple dɔwɔnu siwo wòhiã me, eye wòsɔ nudzɔdzɔ vevitɔwo:
| Database | Dɔwɔwɔ ƒe alɔdzedze | Sɔxɔxɔ si wònyo na | Nu nyuiwo | Nu vɔ̃wo |
|---|---|---|---|---|
| Chroma | Le teƒe / Embedded | Sɛ (ɖoɖo kple dodokpɔ) | Mewɔa dɔ o, wòbɔbɔe, wòwɔa dɔ kple LangChain/LlamaIndex | Menyo na dɔwɔƒe o, mele distributed alo dɔwɔnu gãwo o |
| Qdrant | Ŋutɔ / Cloud | Sɛ kple dome (milɔn geɖe) | Dɔwɔwɔ nyo, API bɔbɔe, agbalẽwo le, wòwɔa mixed retrieval | Ehiã be wòaɖo eme na vɛkta gãwo |
| Milvus | Ŋutɔ (distributed) | Gã (milɔn geɖe) | Wòate ŋu aɖe eme, dɔwɔnuwo katã le, community gã | Dɔwɔwɔ kple ɖoɖo le sesẽ |
| Pinecone | Cloud si wokpɔa gbɔ | Dome kple gã | Mewɔa dɔ o, wòwɔa dɔ enumake | Aƒe sɔ gbɔe, data ƒe sewo ate ŋu ahe na |
| pgvector | PostgreSQL plugin | Sɛ kple dome | Mewɔa dɔ be wòatsɔ nu yeye akpe o, wòate ŋu aƒo kple business data, dɔwɔwɔ bɔbɔe | Eƒe ŋusẽ mede vɛkta database tɔxɛwo o |
6. Dodokpɔ ƒe Nublanuwo Kple Nuxlɔ̃meɖeɖe
- Se vɛkta database ƒe gɔmeɖeɖe nyuie: ANN diɖi nye eƒe gɔmeɖeɖe, menye "vɛkta ɖoɖo" ko o.
- Tiatiaɖoɖo mele be wòaɖo ɖe GitHub Star ŋu ko o, ke boŋ wòaɖo ɖe vɛkta ƒe sɔxɔxɔ, dɔwɔwɔ ƒe alɔdzedze, kple dɔwɔnu siwo wòhiã ŋu.
- Le teknikal nu la, ehiã be wòase HNSW kple IVF algorithm ƒe vovototo kple teƒe siwo wònyo na.
