> After the optimization in LENS-1452, Combinations as mentioned in the jira
> summary can get created. Say the time range queried is {{\[f, t)}}, Candidate
> {{a}} and {{b}} can cover {{\[f, m)}} and candidate {{c}} can cover {{\[m,
> t)}}. Say a Union candidate is represented as {{U(cand1, cand2,...)}}. Then
> the code creates {{U(a,b,c), U(a,c) and U(b,c)}}. If {{U(a,b,c)}} is picked
> as final candidate, then one of {{a}} or {{b}} doesn't resolve partitions and
> {{time_range_in}} clause is left as it is for that.
