Configuring retry strategies

This feature allows developers to configure retry strategies, specifying how many times an operation should be retried before giving up. The `StandardRetryStrategy` is a built-in strategy that can be used to automatically handle retries according to the SDK's standard logic.

const { StandardRetryStrategy } = require('@aws-sdk/util-retry');
const retryStrategy = new StandardRetryStrategy(maxAttempts);

Custom retry strategy

Developers can extend the `RetryStrategy` class to implement custom retry logic. This allows for fine-grained control over when and how retries should be performed, based on the specific needs of the application.

const { RetryStrategy } = require('@aws-sdk/util-retry');
class MyRetryStrategy extends RetryStrategy {
  constructor(maxAttempts) {
    super();
    this.maxAttempts = maxAttempts;
  }
  shouldRetry(error) {
    // Custom logic to determine if a retry should be attempted
  }
  delayBeforeNextRetry(retryCount) {
    // Custom logic to determine the delay before the next retry
  }
}
