Hello,

we have created a graph (or a tree) for time series data as described in 
this article ( 
 
https://github.com/orientechnologies/orientdb-docs/blob/master/Time-series-use-case.md
 
). The actual tree is as follows:

Year -> month (map) -> Month -> day (map) -> Day -> hour (map) -> Hour -> 
minute (map) -> Minute -> second (map) -> Second -> millisecond (map) -> 
Millisecond -> Document 

Document contains also the timestamp as a property alongside the actual 
data values.

Now we are wondering if this tree is actually suitable for one our use 
cases that require a query which "returns all available documents between 
timestamp1 and timestamp2  where the timestamps are epoch timestamps in 
milliseconds and can span several years"? And if it does, what would be the 
most performant query these documents from the tree?

br,
Timo
