Cassandra Schema History

[Mark Bidewell <mb...@gmail.com>]

We have some cassandra tables that have undergone extensive modification
over the life of our application.  This has lead to a significant alter
table history.  It is my understanding that this history is necessary to
process sstables that may contain columns that might have been removed.
Due to the performance limits of the gossip protocol this history makes
restoring snapshots time-intensive.

Is there a a way to, for lack of a better word, "rebase" the schema and
sstables of a table to the latest schema to expunge the history?

Thanks!
