πŸ“‹ Deployment Checklist

βœ… 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)

βœ… Phase 2: GitHub Actions (5 min)

  • Add GitHub Secrets:
    • SUPABASE_URL
    • SUPABASE_SERVICE_ROLE_KEY
  • Test ingestion (manual trigger)
  • Verify documents in Supabase

βœ… Phase 3: HF Spaces (10 min)

  • Create Space (SDK: Docker)
  • Link GitHub repository
  • Add HF Space Secrets:
    • HF_API_TOKEN
    • SUPABASE_URL
    • SUPABASE_ANON_KEY
    • EMBEDDING_MODEL (optional)
    • RESULTS_K (optional)
  • Wait for build completion
  • Test with sample query

βœ… Phase 4: Go Live! (5 min)

  • Share Space URL with team
  • Monitor ingestion logs
  • Gather feedback
  • Plan upgrades

Total Time: ~30-40 minutes


πŸš€ 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.


πŸ“Š Key Features

Ingestion Pipeline

# GitHub Actions runs this automatically
ingest.py
β”œβ”€ Load data/sap_dataset.json
β”œβ”€ Chunk documents (512 tokens, 100 overlap)
β”œβ”€ Compute embeddings (sentence-transformers)
β”œβ”€ Batch insert into Supabase
└─ ~234 chunks from 47 documents

Streamlit App

# Runs on HF Spaces, users interact here
app.py
β”œβ”€ Load SUPABASE credentials from secrets
β”œβ”€ User asks question
β”œβ”€ Compute embedding (HF Inference API)
β”œβ”€ Search Supabase RPC (top-5 results)
β”œβ”€ Generate answer (HF Inference API)
└─ Display with sources

πŸ” Security & Best Practices

Secrets Management

βœ… HF Space Secrets (public, safe):

  • HF_API_TOKEN - Scoped token
  • SUPABASE_URL - Project URL
  • SUPABASE_ANON_KEY - Limited read access (RLS protected)

⚠️ GitHub Secrets (private):

  • SUPABASE_URL - For ingestion
  • SUPABASE_SERVICE_ROLE_KEY - Ingestion only! Never in HF Spaces!

βœ… Supabase RLS Policies:

-- documents table: anon key can SELECT (Streamlit app)
CREATE POLICY "Allow anon read" ON documents
FOR SELECT USING (true);

πŸ“ˆ 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)


πŸ’° 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)
─────────────────────
TOTAL:             $0/month πŸŽ‰

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

πŸ”„ 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

🚨 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

❌ Scalability limited to local resources
❌ No persistent storage
❌ Single ingestion method

New Setup (Supabase Production)

βœ… Scalable pgvector database
βœ… Unlimited documents (scales to 1TB+)
βœ… Persistent cloud storage
βœ… Automated ingestion via GitHub Actions
βœ… Proper separation: code (GitHub) vs data (Supabase)
βœ… Security: RLS policies + key management
