[Gluster-devel] Release 3.10 feature proposal: multi-threaded promotions and demotions in tiering

[Milind Changire]

Currently, there's a single promotion thread and a single demotion
thread serving every tier volume. The individual threads iterate
over the bricks every pass. This can be improved in performance by
assigning multiple promotion and demotion threads to a single brick.
Different bricks can independently promote heated files as well as
demote cooler files quicker to make space for new heated files.
