Hi all
Some time ago I saw previous messages related to caching files locally on
gluster as opposed to keep the on mem-based IO-Cache.
I must admit a dont have for now enough coding skills to help so much achieving
this, coding a new performance xlator from scratch is still
hard for me..
So i was just thinking about what features we would need to get this up and
running and how get them with minor efforts.
I ve write a litlle memo about achieving this issue, perhaps someone can give
it a try and comment about feasibility and costs of incorporate
this into the current development schedules.
Perhaps elaborating this memo a bit more can allow us in a near future to get
this, asuming devs have enough time and they agree on the correctness of
such design.
This approach merely requires in short.
One minor modification to the filter xlator.
A new performance translator auto-prune.
One or more new schedulers "prune-big", "prune-lru" etc..
Minor (?) Modifications to afr xlator
Please tell me what you think about this proposal.
Regards Angel
