Hey guys,

What is the plan for getting Tachyon/off-heap support for the columnar
compressed store?  It's not in 1.1 is it?

In particular:
 - being able to set TACHYON as the caching mode
 - loading of hot columns or all columns
 - write-through of columnar store data to HDFS or backing store
 - being able to start a context and query directly from Tachyon's
cached columnar data

I think most of this was in Shark 0.9.1.

Also, how likely is the wire format for the columnar compressed data
to change?  That would be a problem for write-through or persistence.

thanks,
Evan
