I using ideas expressed in the time series use case listed below.

https://github.com/orientechnologies/orientdb/wiki/Time-series-use-case

I have a case where I I've broken down the graph by the hour in my time 
series graph, but updating the logs links is having a huge impact on 
performance.

for every log insert I need to update the hour record to add the link to 
the LINKSET with this update 

update <RID> add logs =<RID>

If I don't do this update to update the link to the hour object, I am 
getting approximately 11,000 events per second.. Once I add in this update, 
I end up lowering this to about 700 to 800 events per second.

I am currently looking at processing 5000 events per second so in one hour 
there would be 18,000,000 RID's stored per hour block.. Is this practical?
