Benedict created CASSANDRA-6806:
-----------------------------------
Summary: In AtomicBTreeColumns, construct list of unwinds after a
race lazily
Key: CASSANDRA-6806
URL: https://issues.apache.org/jira/browse/CASSANDRA-6806
Project: Cassandra
Issue Type: Improvement
Reporter: Benedict
Assignee: Benedict
Priority: Minor
Fix For: 3.0
Currently we store these in a List, but this is wasteful. We can construct them
lazily from a diff between the original and partially constructed replacement
BTree. The UpdaterFunction could define a method to be passed such a collection
in the event of an early abort.
