Bryan Talbot commented on CASSANDRA-5228:
-----------------------------------------
It sounds like this would be an "Age Tiered Compaction Strategy"?
One of our busiest use cases involves logging performance data with the same
TTL for all columns of a row. The row is never updated once all columns are
written to once. For example, metrics per-second might be kept for 3 days,
metrics per-minute kept for 3 weeks, and metrics per-hour or day kept longer.
It would be great to avoid all the excess compaction IO work on rows that never
change and haven't expired yet. This sounds like it would greatly extend the
performance of cassandra (by reducing compaction-IO overhead) for us and many
other similar workloads.
