eric baldeschwieler commented on HDFS-5851:
-------------------------------------------
A very interesting design space!
How does this relate to Tachyon's design goals?
What is the target use case?
What durability / replication guarantees are you providing?
What happens when RAM is exhausted?
Assuming low durability, what happens when a file or block is lost?
> Support memory as a storage medium
