Support for clickhouse cluster in superset - alt_hosts

[royxact]

Can you please add support for alt_hosts in the superset connection string?

Thanks

What does that mean? The clickhouse clients don't have support for falling back to other hosts.

Hi @genzgd !
It's a parameter found in the clickhouse python driver https://clickhouse-driver.readthedocs.io/en/latest/api.html
Also the go driver has it.
So I thought it makes sense to support it here as well.
Thanks

Ah, I understand. Just to clarify, this works in superset with clickhouse-driver?

In any case, I think that makes this a duplicate of #74?

Correct, seems a similar requirement. With alt_hosts behavior, you try the host, and if it doesn't respond you go the alternative. So it's more of a fail over rather than a load balancer.
