What is the recommended Start and End time and frequency to pull events?

When it comes to choosing the correct Start and End time of fetching events, there are a couple of options:

...

Note

Not Recommended

Discrete Time Window (no overlap)

Example

  • Start=Now-180 minutes,

  • End=Now-165 minutes,

  • Frequency=Every 15 minutes

Although this option is simpler from a data parsing perspective, we do not recommend it.

  • More Latency:   This options option requires choosing a period in the past to avoid missing data, thus increasing the latency which is bound by the start time-frequency.

  • Incomplete Data:  Calling only once means any AIS data that is delayed will be missed and not picked up in a subsequent call. The closer the start time is to real time, the more missed data/events there will be.

What interval should be used to fetch events? (How far back should we go?)
