Queues & Workers

NodeJS workers in AWS EBS

SQS Daemon by AWS

  1. nginx sits between sqsd and workers for no good reason!
    • Its presence creates more issues:
      • 5xx errors that claim "loss of connection to upstream server"
      • connection errors like ECONNRESET and various other socket hangup problems
  2. sqsd itself is quite buggy too
    • messages end up on dead letter queue (DLQ) despite the worker reporting 200 OK for success.
