π Deployment Checklist
β Phase 1: Supabase Setup (10 min)
- Create Supabase project (supabase.com)
- Enable pgvector extension
- Create documents table
- Create search_documents() RPC function
- Get API credentials (URL, anon key, service_role key)
β Phase 2: GitHub Actions (5 min)
- Add GitHub Secrets:
SUPABASE_URLSUPABASE_SERVICE_ROLE_KEY
- Test ingestion (manual trigger)
- Verify documents in Supabase
β Phase 3: HF Spaces (10 min)
- Create Space (SDK: Docker)
- Link GitHub repository
- Add HF Space Secrets:
HF_API_TOKENSUPABASE_URLSUPABASE_ANON_KEYEMBEDDING_MODEL(optional)RESULTS_K(optional)
- Wait for build completion
- Test with sample query
β Phase 4: Go Live! (5 min)
- Share Space URL with team
- Monitor ingestion logs
- Gather feedback
- Plan upgrades
Total Time: ~30-40 minutes
π Quick Start
For Immediate Deployment
Follow this guide: DEPLOYMENT_SUPABASE.md
Step-by-step instructions with copy-paste commands.
For Detailed Understanding
Then read: SUPABASE_SETUP.md
Deep dive into configuration, troubleshooting, and optimization.
π Key Features
Ingestion Pipeline
# GitHub Actions runs this automatically
ingest.py
ββ Load data/sap_dataset.json
ββ Chunk documents (512 tokens, 100 overlap)
ββ Compute embeddings (sentence-transformers)
ββ Batch insert into Supabase
ββ ~234 chunks from 47 documents
Streamlit App
# Runs on HF Spaces, users interact here
app.py
ββ Load SUPABASE credentials from secrets
ββ User asks question
ββ Compute embedding (HF Inference API)
ββ Search Supabase RPC (top-5 results)
ββ Generate answer (HF Inference API)
ββ Display with sources
π Security & Best Practices
Secrets Management
β HF Space Secrets (public, safe):
HF_API_TOKEN- Scoped tokenSUPABASE_URL- Project URLSUPABASE_ANON_KEY- Limited read access (RLS protected)
β οΈ GitHub Secrets (private):
SUPABASE_URL- For ingestionSUPABASE_SERVICE_ROLE_KEY- Ingestion only! Never in HF Spaces!
β Supabase RLS Policies:
-- documents table: anon key can SELECT (Streamlit app)
CREATE POLICY "Allow anon read" ON documents
FOR SELECT USING (true);
π Performance
| Operation | Time | Tool |
|---|---|---|
| Load document | <1s | Query Supabase |
| Compute embedding | 50-100ms | HF Inference API |
| Vector search (top-5) | 10-50ms | pgvector IVFFlat |
| Generate answer | 10-30s | HF Inference API |
| Total response | 10-30s | Dominated by LLM |
First request (cold start): +30-60s Subsequent requests: +10-20s (LLM cached)
π° Cost Analysis
Free Tier (Default)
Supabase: $0 (500MB DB, 2GB storage)
HF Spaces: $0 (5+ concurrent users)
HF Inference API: $0 (rate limited but generous)
GitHub Actions: $0 (2000 min/month)
βββββββββββββββββββββ
TOTAL: $0/month π
When to Upgrade
Upgrade Supabase to Pro ($25/mo) when:
- Documents exceed 500MB
- Users exceed 100/month
- Searches exceed 1000/day
- Need higher rate limits
Upgrade HF Spaces to paid when:
- Users exceed 5 concurrent
- Need GPU for faster inference
π Maintenance
Adding More Documents
# 1. Update local dataset
python tools/build_dataset.py
# 2. Push to GitHub
git add data/sap_dataset.json
git commit -m "Add new SAP docs"
git push origin main
# 3. GitHub Actions auto-runs ingestion
# 4. New documents available in Supabase immediately
# 5. HF Spaces app auto-syncs
Monitoring
GitHub:
β Actions β "Ingest & Deploy" β View logs
Supabase:
β Logs β Monitor API calls and errors
HF Spaces:
β Logs β Monitor app startup and errors
π¨ Troubleshooting
| Issue | Solution |
|---|---|
| "pgvector not found" | Enable extension in Supabase SQL Editor |
| "RPC function not found" | Create search_documents() function |
| "No results from search" | Verify documents table has rows |
| "Embedding dimension error" | Model uses 384 dims, table is VECTOR(384) |
| "Slow ingestion" | Increase BATCH_SIZE in ingest.py |
| "App won't start" | Check secrets are correct in HF Space |
| "Can't connect to Supabase" | Verify URL and anon key are correct |

β¨ What's Different
Old Setup (HF Spaces Local)
β FAISS index in repo (~100MB)
β Scalability limited to local resources
β No persistent storage
β Single ingestion method
New Setup (Supabase Production)
β
Scalable pgvector database
β
Unlimited documents (scales to 1TB+)
β
Persistent cloud storage
β
Automated ingestion via GitHub Actions
β
Proper separation: code (GitHub) vs data (Supabase)
β
Security: RLS policies + key management
