Don't persist TTL for expiring columns
--------------------------------------
Key: CASSANDRA-2620
URL: https://issues.apache.org/jira/browse/CASSANDRA-2620
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Stu Hood
Priority: Minor
Fix For: 1.0
We persist both the TTL (5 seconds from now) and the localExpirationTime (the
local time at +5 seconds) for expiring columns, but the TTL is never used
again, except when we return expiring columns to clients.
Rather than storing the TTL to return to clients, we could calculate a delta
TTL value by subtracting the current time from the localExpirationTime, and
save 4 bytes on disk.
