In the production environment, there is no option to clear the Redis database after each redeploying/restarting of the applications (ex. k8s with many pods).
The are many reasons:
this database can be used for other purposes, but you deprecate RedisStorage with a separate database selection
more complex deploy/restart operations with additional steps to clear Redis
users can use Reporting at this moment
Please add TTL option for RedisStorage in ReportServiceConfiguration
