> ABFS: Optimizations for Retry Handling and Throttling

> Key: HADOOP-19357
> URL: https://issues.apache.org/jira/browse/HADOOP-19357
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs/azure
> Affects Versions: 3.4.0, 3.4.1
> Reporter: Manika Joshi
> Assignee: Manika Joshi
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.5.0

>
> Given the significant improvements on the service side over the past few
> years, the current client-side retry mechanism, which enforces 5-6 minutes of
> sleep time with jitter, is now excessive. Therefore, we are realigning the
> retry and throttling logic thresholds.
> Since the service can now handle higher traffic rates, we aim to enhance
> driver performance by setting the following configurations as default:
> * {*}Client-side throttling (CST){*}: Off
> * *Client Backoff* - 500ms (reduced from 3sec)
> * *Max Backoff* - 25s (reduced from 30sec)
> * *Min Backoff* - 500ms (reduced from 3sec)
