Could you explain BucketType.WILDCARD usage ?

Hi, i am trying to use datacube to calculate kpis with huge cardinality of dimesions. And i have a requirement which i tried to explain below.

Suppose i defined a rollup like dim1_dim2_dim3_dim4 and i want to read all counters with one readbuilder like dim1_dim2_dim3_*
Can i use BucketType.WILDCARD for this or it exists for another use case ?
Could you explain wildcard with an example ?

thanks for this project, and i am willing to write a redis db harness

You would simply omit the last dimension from your read builder. the WILDCARD bucket type is mostly for internal use.
