-------------------------------------
Hello, that's great that the community look at this!
If I can add an input, the point 2.g regarding the QOS and a user not
impacting/disrupting other users of the platform is for me something very
important and not a nice to have.
We do see in our datacenter (with other storage technologies at scale) some
usecase or users hammering of requests the storage cluster and heavily
impacting the other usecase.
Being able to guarantee fair usage of a platform is key for the multi-tenancy
in my opinion. So it will be really great if this could be implemented with
this multi-tenancy epic.
Im not an expert like you guys but I believe that there is at least the 2
following options:
- Being able to set a maximum number of S3 request / sec per user for each S3
gateway or at a global level for the ozone cluster
- Have the S3 gateway to implement a more smart management of the incoming
request like the namenode do with the FairCallQueue. It will keep track of the
number of request per user in the last 5 seconds and prioritize the request of
the different user based on their load on the platform. So not a FIFO model.
This will only provide QOS on the S3 part, when ozone is used with s3 and with
the Hadoop interface at the same time that will only half work. Maybe someone
has an idea to over s3 and Hadoop interface at the same time?
