Aws-sdk-js: How to configure maxRetries and retryDelays for SQS, S3, SES. What are there default values?

Created on 8 Sep 2015 · 3Comments · Source: aws/aws-sdk-js

We received Inaccessible host issue for SQS and S3 and as per recommendation in #528 we upgraded to latest sdk.
We are unable to find out the default values of maxRetries and the delay between retries. Just to be sure we wanted to know these numbers. Can anyone provide the information.

The default retry count for all service clients is 3. You can increase the default retry count by setting the maxRetries option when constructing a service client.

For example:

var s3 = new AWS.S3({maxRetries: 10});

The delay between retries is a calculated number and increases exponentially with the number of retries per this formula
delay_n delay = 2ⁿ * 30 milliseconds

For example:

delay₀ delay = 2⁰ * 30 = 30 ms
delay₁ delay = 2¹ * 30 = 60 ms
delay₂ delay = 2² * 30 = 120 ms

Hope this helps clarify things.
