The consistency level also is One.

Those are for "majority of replicas in a single datacenter." The code isn't

yes, it can be a significant one if you have a lot of data.
you can look at the compaction mbean for progress on that side of things.

Hey Todd,
Repair involves 2 major compactions in addition to the streaming. More
information is logged about the compactions and repair when you are using DEBUG.
Do you think you might have restarted the node being repaired during the
streaming process? I'm not sure we have good handling for th

Above link should help. He explains the data model and then gives an example
of building twitter like service on top of cassandra.

You mention indexing - iirc, cassandra is adding this as an internal feature
