Hi osquery team, does osquery allow concurrent running of queries on host? or never or it could be controlled?

Distributed queries can run concurrently with scheduled queries, but each distributed query or scheduled query is run serially with their own kind, and no, there’s no control over that.

so only scheduled queries can run in concurrent way, live query cannot?

What I meant is that a live query can run at the same time as a scheduled one, but a live query cannot run at the same time another live query runs, and the same thing with scheduled queries. There are 2 threads, one handles live queries, the other scheduled queries.
