Buckets values based on fixed size ranges. The Bucketing
transformation can provide all of this functionality, but requires more
configuration. This message is provided as a convenience to the user for
simple bucketing strategies.
The transformed value will be a hyphenated string of
{lower_bound}-{upper_bound}, i.e if lower_bound = 10 and upper_bound =
20 all values that are within this bucket will be replaced with “10-20”.
This can be used on data of type: double, long.
If the bound Value type differs from the type of data being transformed,
we will first attempt converting the type of the data to be transformed
to match the type of the bound before comparing.
Required. Upper bound value of buckets. All values greater
than upper_bound are grouped together into a single bucket;
for example if upper_bound = 89, then all values greater
than 89 are replaced with the value “89+”.
