Timeline with lazy loading.

Does timeline support lazy loading from database through LazyQueryContainer?
I “feed” my timeline with LazyQueryContainer but the timeline still fetches all data from DB regardless of the container batchsize.
In order to draw the full scrollbar, the container seems to need ALL data, but this approach kills lazy loading. I would happily relinquish the scrollbar area or at least limit its size to a given timeperiod, is that possible?
