I'm trying to run a dashboard with 12 slices. I noticed that only six slice queries are running concurrently. Is there any way to increase the number? Is there a way to run all the 12 slice queries at the same time?

The limit is the result of the browser's limit on concurrent requests to the same domain. At Preset we're considering a different architecture that will get around that limit, but this is well in the future at this point. For now, you can domain-shard your requests. If that sounds interesting, other contributors can speak more to how that's accomplished.

Thanks for the response. I would love to know more about domain-sharding.

I have another question. While using Oracle BI, I've never faced this limit issue. So, is this a limitation of Superset?

Hi @ArvindRaj17 this is a limit in Superset, given the way you've got it deployed currently. I believe @betodealmeida, @mistercrunch, or @john-bodley could provide more information on domain sharding.
