##Controlling Upload WithFlushPolicies

Tomoregranularlycontrol when events are uploaded you can use `FlushPolicies`.**This will override any setting on `flushAt` and `flushInterval`, but you can use `CountFlushPolicy` and `FrequencyFlushPolicy` to have the same behaviour respectively.**

## Flushpolicies

Tomoregranularlycontrol when events are uploaded you can use `FlushPolicies`.

AFlushPolicydefinesthestrategyfordeciding when to flush, this can be on an interval, on a certain time of day, after receiving a certain number of events or even after receiving a particular event. This gives you even more flexibility on when to send event to Segment.
