We have hasbe table with rowkey as user id + timestamp. Around 70% of our usecases use user id as part of scan. But other 30% scenarios does not depend on user id. It's like fetch all users who had done changes between this time. Currently we are storing the timestamp as column and using Columnvaluefilter to get the results. Is there a way better way to do this.

Thanks in advance.
