time series - Dynamodb UUID range key -


i have dynamodb table consisting of hash key , range key, trying model time series data.

the hash key userid , range key time-stamp of day of entry. problem cannot have more 1 entry given day; time-stamp not @ exact time these records may entered in retrospect.

the table looks this:

userid | timestamp | fields... 1234   | 9/10/17   |  ...

the query want make read this:

"for user 1234 show me records between date , now"

is possible replace timestamp range key uuid has timestamp in can have more 1 entry given day? know cassandra can use timestamp build uuid query dates.

or

is there better way model data?
