The solution combines multi-DO scaling with 5 Hiro API keys, fast-path KV caching in the Worker, round-robin load balancing, and queue prioritization. This enhances throughput, reduces latency for cache hits, and distributes load evenly. + +## Key Components +- **Multi-DO Scaling**: 5 DO instances, each tied to one Hiro API key via hashed DO IDs. +- **Fast-Path Caching**: Check KV directly in the Worker for read-only requests; bypass DO if hit. +- **Round-Robin Routing**: For cache misses/busts, cycle through DOs using a KV counter. +- **Queue Prioritization**: In each DO's RequestQueue, prioritize non-busting requests. + +## Implementation Steps + +### 1. Update src/config.ts (AppConfig) +- Add `HIRO_API_KEYS` as an array from env. +- Add methods: `getHiroDoIds()` (hash keys to DO IDs), `getKeyForDoId()` (reverse lookup). + +### 2. Update src/index.ts (Main Worker) +- Initialize CacheService and CacheKeyService. +- For /contract-calls/read-only/, parse params/body, generate cache key, check KV if !bustCache. +- On miss/bust, use round-robin to select DO via KV counter. + +### 3. Update src/durable-objects/contract-calls-do.ts (ContractCallsDO) +- Assign hiroApiKey based on DO ID. +- Pass key to StacksContractFetcher. +- When enqueuing, set priority (higher for non-busts). + +### 4. Update src/services/stacks-api-service.ts (StacksApiService) +- Accept hiroApiKey in constructor. +- Use it for API auth middleware. + +### 5. Update src/services/stacks-contract-data-service.ts (StacksContractFetcher) +- Accept and forward hiroApiKey to StacksApiService. + +### 6.

If so, provide the file for review. -> File added; mappings are standard (e.g., NOT_FOUND=404). - During testing, if persistent 500s occur, can we access server-side logs for a specific requestId (e.g., from test output) to trace upstream errors? -> Yes, viewable but use minimal logging for cost. - Set HIRO_API_KEYS in the environment to avoid rate limiting issues (as per original query, handled separately). -> Officially set via wrangler secret put. +- In test_contract_calls.sh, why does test_endpoint report 500 for invalid endpoint when manual curl shows NOT_FOUND body (expected for 404)? Add tests/utils.sh to chat for review if needed to check status parsing logic. -> File added; fixed parsing by separating status curl and adjusting headers/body extraction.
