+# Vectorize Gotchas
+
+## Critical Warnings
+
+### Async Mutations
+Insert/upsert/delete return immediately but vectors aren't queryable for 5-10 seconds.
+
+### Batch Size Limit
+**Workers API: 1,000 vectors max per call (HTTP API: 5,000).** Silently truncates if exceeded.
+
+```typescript
+// ✅ Chunk into 1000 (Workers API limit; HTTP API allows 5000)
+for (let i = 0; i < vectors.length; i += 1000) {
+  await env.VECTORIZE.upsert(vectors.slice(i, i + 1000));
+}
+```
+
+### Metadata Truncation
+`returnMetadata: "indexed"` returns only first 64 bytes of strings. Use `"all"` for complete metadata (but max topK drops to 20).
+
+### topK Limits
+
+| returnMetadata | returnValues | Max topK |
+|----------------|--------------|----------|
+| `"none"` / `"indexed"` | `false` | 100 |
+| `"all"` | any | **20** |
+| any | `true` | **20** |
+
+### Metadata Indexes First
+Create BEFORE inserting - existing vectors not retroactively indexed.
+
+```bash
+# ✅ Create index FIRST
+wrangler vectorize create-metadata-index my-index --property-name=category --type=string
+wrangler vectorize insert my-index --file=data.ndjson
+```
+
+### Index Config Immutable
+Cannot change dimensions/metric after creation. Must create new index and migrate.
+
+## Limits (V2)
+
+| Resource | Limit |
+|----------|-------|
+| Vectors per index | 10,000,000 |
+| Max dimensions | 1536 |
+| Batch upsert (Workers / HTTP API) | **1,000 / 5,000** |
+| Indexed string metadata | **64 bytes** |
+| Metadata indexes | 10 |
+| Namespaces | 50,000 (paid) / 1,000 (free) |
+
+## Common Mistakes
+
+1. **Wrong embedding shape:** Extract `result.data[0]` from Workers AI
+2. **Metadata index after data:** Re-upsert all vectors
+3. **Insert vs upsert:** `insert` ignores duplicates, `upsert` overwrites
+4. **Not batching:** Individual inserts ~1K/min, batched ~200K+/min
+
+## Troubleshooting
+
+**No results?**
+- Wait 5-10s after insert
+- Check namespace spelling (case-sensitive)
+- Verify metadata index exists
+- Check dimension mismatch
+
+**Metadata filter not working?**
+- Index must exist before data insert
+- Strings >64 bytes truncated
+- Use dot notation for nested: `"product.category"`
