   alt_hosts – list of alternative hosts for connection. Example: `clickhouse://username:password@host:port/database?alt_hosts=host1:port1,host2:port2`
   
   It will assure that if the host is failing it will connect to the alternate host for the high availability. 
   
   As in Apache superset this parameters are not acceptable, may be it's a problem of sqlachemy-clickhouse driver. 
   
   Also I tried clickhouse-sqlachemy driver which depends on clickhouse-driver and the driver gets loaded and connection is established using TCP protocol, but somehow did not received acknowledgement. It also a problem of the driver here. 
   
    How to assure high availability of clickhouse database while connecting using superset?
   
   8123 worked because it runs on the http protocol.
