I wish to store a count of 30-day trailing event data (e.g. # of clicks
in past 30 days) and ended up reading the documentation for setTimeRange
in the Increment operation.
http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/Increment.html#getTimeRange%28%29
I was hoping someone could clarify if it works as I'm imagining in this
example scenario.
1) Current click count is 0
2) I process a click and I perform an increment operation with the time
range set to minStamp = now and maxStamp = 30 days from now
3) I query for the value immediately and find it to be 1
4) Assuming no other clicks come in, if I query for the value in 31
days, it will be returned as 0
In essence, I'm looking for a way to set a TTL on my increment
operation. Is this how it actually works? The documentation is a bit
vague and I could imagine several other scenarios.
