Subject Long-life TTL and extending TTL
Date Mon, 10 Sep 2012 09:47:31 GMT
Hi there,

I'm working on a project that might want to set TTL to roughly 7 years.
However it might occur that the TTL should be reduced or extended. Is there
any way of updating the TTL without being in need of rewriting the data
back again? This would cause way to much overhead for this.

If not, is running a Map/Reduce task on the whole data set the "best"
option or should I think in a difference approach for this challenge?

My last question is regarding to a long term TTL, does this have any
negative impact on the cluster? Maybe during compaction, repair,

Best regards,

Robin Verlangen
