How many users does Presto DB support?
<p>We are looking into Presto DB documents and blogs to understand its usage for one of the projects. One of the questions that we have is </p>

<p>"How many users can concurrently fire queries in a presto DB?"</p>

<p>Is there a fixed number of users or we can have as many users login?</p>

<p>Is there a limit on number of concurrent queries which can be fired? (other than max concurrent queries can be set for user in queue config)</p>
