FIDO is Explo’s data orchestration service. There are a lot of benefits compared to the previous data querying architecture including:
  • Persistent database connection management, eliminating connection latency for queries (connection and SSH tunneling time)
  • Longer timeouts configurable for queries
  • Querying databases within a certain region of the world for data residency requirements and speed optimizations
  • Connect via SSH tunneling, AWS PrivateLink, and more
