Azure Key Vault - Hi, As stated [here](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/eventhub/azure-eventhub/TROUBLESHOOTING.md#partition-ownership-changes-frequently) partitions keep rebalancing frequently even though consumers don't change.

## The fix

If Event Hubs partition ownership keeps flipping with a constant number of consumers, check where your checkpoint store lives. Two reporters had their Blob or File Storage checkpoint store in a different region than the consumers; moving the storage into the consumer's region dropped lost-ownership events to zero.
