title: How many concurrent requests can i send to cognito Access token endpoint - POST /oauth2/token
body: <p>I am encountering an error with cognito: org.springframework.web.client.HttpClientErrorException$TooManyRequests: <strong><em>429 Too Many Requests</em></strong></p>
  
  <p>I believe this is happening when the application is sending too many requests to Cognito. Therefore wanted to know, what is the max concurrent limit Cognito can handle?</p>
