Overloaded gateway, slowness, performance issues, old data.
Conflation is an optional and less drastic method of coping with an overloaded gateway than a data quality suspension. When the data queues (containing incoming sampler updates from netprobes) become backlogged due to the gateway being unable to process them as fast as they arrive, conflation allows the gateway to discard out-of-date cell updates and only process and publish the latest cell values.
When a Netprobe has published several updates to the same cell before the gateway has processed the first update:
- Update cell from 1 to 2
- Update cell from 2 to 3
- Update cell from 3 to 4
- Update cell from 4 to 5
With conflation active, gateway only publishes the latest value:
- Update cell from 1 to 5
As this could potentially result in the gateway discarding important updates, or missing short-lived events, conflation is disabled by default and should only be used with care.
