Hello there,
I have had a look in the documentation and was wondering, is it possible to cancel a query once it has been submitted using ClientQuery/ClientSession?
Would calling close() on ClientQuery do that?

You could use jobs:eval(query…), where you provide the query and you get back an Id for the job. You can then cancel the job using jobs:stop(id)

Hi Shaun,
There is no way to cancel a running query with the client/server architecture. The reason is that the socket communication is unidirectional: Once a job has been sent to the the server, the response will be retrieved, and no other command can be sent in parallel.
If you do not need admin permissions, you can set a global timeout via the
TIMEOUT option [1].
Hope this helps,
Christian
