Thanks Venky for sharing the details.
I have included Pranith and Atin for a specific question:
With current implementation of erasure coding, Do we have the capability of detecting and correcting bit rot?
Let's say we have fragments of a file on multiple bricks and a read request is sent to the bricks, a brick doesn't respond as it may have disk(s) damaged by bit rot or any other failure. Will EC detect and correct bit rot in this case?
Regards
Alok

Hey folks,
Myself and Raghavendra (@rabhat) have been discussing about BitRot[1]
and came up with a list of high level tasks (breakup items) captured
here[2]. The pad will be updated on an ongoing basis reflecting the
current status/items that are being worked on. As always, contributions
in any form (design, code, doc, etc..) are more than welcome (just make
sure you're heard on the pad/email :))
