-------------------------------------
Summary: S3 QoS
Key: HDDS-8211
URL: https://issues.apache.org/jira/browse/HDDS-8211
Project: Apache Ozone
Issue Type: New Feature
Components: S3
Reporter: Mohanad Elsafty
Assignee: Mohanad Elsafty
Attachments: image.png
The target of QoS is to give all the users the opportunity to use S3Gateway
even during periods of high load by limiting users making too many requests so
the service becomes available for everyone.
The idea is taken from "{*}Apache Hadoop Fair Call Queue{*}"

* Users will be making requests to S3Gateway which is intercepted by
*ThrottlerFilter* that takes action whether to proceed with this request or
reject it with the help of a scheduler.
* At the moment there is one usable scheduler implementation
*DecayRequestScheduler.*
* *DecayRequestScheduler* keeps information about each user making requests
and the availability of s3gateway handlers.
* If all handlers are busy and some users are making too many requests it will
start rejecting incoming requests with "
Service Unavailable" response.
* It also decays the number of user's requests count over the time.
