Hi @Sai Krishna Cheruvu​ 

If you haven't configured your warehouse with an autoscale capacity (min clusters = max clusters = 1), you have probably filled the queue with your first 10 queries (See. https://learn.microsoft.com/en-us/azure/databricks/sql/admin/sql-endpoints#queueing-and-autoscaling or the equivalence according your cloud provider).

If those 10 queries are big ones, you should increase your autoscale capacity and depending on these queries' execution profile, Databricks will automatically upscale your warehouse to deliver the expected concurrency level according the algorithm given in the documentation.
