@ -22,5 +22,9 @@ we could consider adding a better dynamic trace sampling mechanism at the backen
when throughput goes over the threshold, active the sampling rate to 100%->10% step by step,
which means you could get the OAP and ES 3 times more powerful than usual, just ignore the traces at hot time.
### Is MQ transport acceptable even there are several side effects?
Even MQ transport is not recommended from the production perspective, SkyWalking still has optional plugins named
`kafka-reporter` and `kafka-fetcher` for this feature since 8.1.0.
### How about MQ metrics data exporter?
I would say, it is already available there. Exporter module with gRPC default mechanism is there. It is easy to provide a new implementor of that module.
