Reading "Memory Considerations" section at the bottom of
and want to confirm:
Just because you use the interval functionality to group values from a
field in buckets does not reduce the amount of memory needed.
For example, if there are 1000 distinct values in field X, if you then do a
histogram facet on X and bucket values into 100 buckets, the memory needed
to hold this is still the same as if bu interval was used for bucketing.
In other words, even if you "bucketize", it is worth reducing the number of
distinct values in a field by, for example, rounding up timestamps to
minutes or hours or even days.
Is the above all correct?
