Hello @Shiva Lakshman Nallakatta ,
welcome to this moderated Azure community forum.
Azure Data Explorer has no standard default load balancer to route message to difference clusters.
I checked the dynamic routing logic but this only route message within one cluster.
There is this GitHub project offering an "Engine able to compute delta between ADX clusters (and/or Kusto scripts) and generate update scripts".
You probably need to build some load balancing logic yourself on this repo.
Perhaps this could work for you?
So if you are able to distribute your messages over multiple event hubs, each eventhub could route messages to a specific cluster.
If the response helped, do "Accept Answer". If it doesn't work, please let us know the progress. All community members with similar issues will benefit by doing so. Your contribution is highly appreciated.
