Powering Indeed’s Agentic Talent Scout with Federated Subscriptions
summary
Indeed replaces Server-Sent Events with Apollo Federated Subscriptions and cuts P95 response time by 22% P95 reduction, streaming rich structured messages from a Scout conversation subgraph through Apollo Router that hydrates federated entities (about 40 supergraph subgraphs) and fetches data via HTTP while the agent core publishes to Redis pub/sub. Multi-agent serial replies arrive about 2s faster first agent delivery. Built in nine months, uses langraph for agents, supports a scoped conversation subscription schema (progress, message, response end) and falls back to polling for ~3% of corporate networks.
