Constant Summary collapse

AMAZON_PROBLEMS =

Text, if found in an error message returned by AWS, indicates that this may be a transient error. Transient errors are automatically retried with exponential back-off.

[ 'internal service error', 
  'is currently unavailable',
  'no response from',
  'Please try again',
  'InternalError',
  'Internal Server Error',
  'ServiceUnavailable', #from SQS docs
  'Unavailable',
  'This application is not currently available',
  'InsufficientInstanceCapacity'
]
RAISE_ON_TIMEOUT_ON_ACTIONS =

Raise an exception if a timeout occures while an API call is in progress. This helps to avoid a duplicate resources creation when Amazon hangs for some time and RightHttpConnection is forced to use retries to get a response from it.

If an API call action is in the list then no attempts to retry are performed.

Class Method Details

.amazon_problems ⇒ Object

Returns a list of Amazon service responses which are known to be transient problems. We have to re-request if we get any of them, because the problem will probably disappear. By default this method returns the same value as the AMAZON_PROBLEMS const.
