Anu Engineer commented on HDFS-7343:
------------------------------------

[~drankye] Thanks for the confirmation on Kafka. It does address large part of my concern.
I look forward to seeing an updated design doc that contains the final design and what we
are solving in the first iteration and how.

> As discussed in HDFS-7285, it would be better to have a comprehensive and flexible storage
policy engine considering file attributes, metadata, data temperature, storage type, EC codec,
available hardware capabilities, user/application preference and etc.
> Modified the title for re-purpose.
> We'd extend this effort some bit and aim to work on a comprehensive solution to provide
smart storage management service in order for convenient, intelligent and effective utilizing
of erasure coding or replicas, HDFS cache facility, HSM offering, and all kinds of tools (balancer,
mover, disk balancer and so on) in a large cluster.
