Apollo Performance Tuning

Overview

Optimize Apollo.io API performance through response caching, connection pooling, bulk operations, parallel fetching, and result slimming. Key insight: search is free but slow (~500ms), enrichment costs credits — cache aggressively and batch enrichment calls.

Prerequisites

• Valid Apollo API key
• Node.js 18+

Instructions

Step 1: Connection Pooling

Reuse TCP connections to avoid TLS handshake overhead on every request.

// src/apollo/optimized-client.ts
import axios from 'axios';
import https from 'https';

const httpsAgent = new https.Agent({
  keepAlive: true,
  maxSockets: 10,
  maxFreeSockets: 5,
  timeout: 30_000,
});

export const optimizedClient = axios.create({
  baseURL: 'https://api.apollo.io/api/v1',
  headers: { 'Content-Type': 'application/json', 'x-api-key': process.env.APOLLO_API_KEY! },
  httpsAgent,
  timeout: 15_000,
});

Step 2: Response Caching with Per-Endpoint TTLs

// src/apollo/cache.ts
import { LRUCache } from 'lru-cache';

// Different TTLs based on data volatility
const : <, > = {
  :  *  *  * ,    
  :  *  *  * ,              
  :  *  * ,       
  :  *  * ,         
  :  *  * ,                 
};

 cache =  <, { : ; :  }>({
  : ,
  :  *  * ,
  :  .(v).,
});

 ():  {
   ;
}

   cachedRequest<T>(
  : ,
  :  <T>,
  : ,
): <T> {
   key = (endpoint, params);
   ttl = [endpoint] ??  *  * ;
   cached = cache.(key);

   (cached && .() - cached. < ttl)  cached.;

   data =  ();
  cache.(key, { data, : .() });
   data;
}

  () {
   { : cache., : cache. };
}
