- Clarify what the memory limiter does.
- Set expectations from receivers, how they are supposed to react
when the memory limiter refuses the data.
- Add a test that demonstrates that memory limiter does not lose data
if the receiver and exporter behave according to the contract.
All receivers must adhere to this contract. See for example
an issue opened against filelog receiver:
https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/20511
Note that there are no functional changes to the memory limiter.
Future work: one additional thing we can do is implement a backoff
logic in the memory limiter. When in memory limited mode the processor
can introduce pauses before it returns from the ConsumeLogs/Traces/Metrics
call. This will allow to slow down the inflow of data into the Collector
and give time for the pipeline to clear and memory usage to return to the
normal. This needs to be explored further.
