Two trigger conditions for scaling down triggers Kafka consumers - Both condition should be true

[benfrankvbf]

In our project, scaling up and down of the consumers are happening considering the lagThreshold parameter in the scaledobject.

We have a scenario where we want to scale down those consumers only after it met two trigger conditions as mentioned below

1. Lagthreshold parameter
2. The number of consumed events in the last minute (metric is available from prometheus)

According to the Keda documentation
"KEDA will start scaling as soon as when one of the triggers meets the criteria. Horizontal Pod Autoscaler (HPA) will calculate metrics for every scaler and use the highest desired replica count to scale the workload to"

Challenge we face here is - we need a single trigger condition for scale up and two condition for scale down (both should be met)

Let us know if you have any suggestion or need more information
