Streamlining Access to NASA Earth Science Data with GraphQL
summary
GraphQL wraps NASA’s CMR metadata APIs to present a single, consistent schema that hides disparate endpoints and formats, serving 2 billion metadata records while honoring a <1s query SLA. The implementation routes requests to faster Elasticsearch or legacy DBs as needed, adds cursor-based paging to replace brittle page schemes, cuts redundant roundtrips, and lets services be swapped or retired — the rollout even retired nearly a million lines of code and succeeds in shrinking payloads and simplifying clients.
