Autodesk splits 100‑TB OpenSearch index into four domains, speeding 2.3 B‑doc queries
Facing query latency and scaling limits on a single 100 TB index holding 2.3 billion documents, Autodesk re‑architected its Elasticsearch 7.1.1 domain into four multi‑index OpenSearch Service domains. Using the Migration Assistant and a smart routing layer, they redirected queries only to relevant shards, restoring fast search for millions of users.
