concurrency limit

[yanggaosc]

Thank you for providing this handy library!

I notice that you keep a local counter of calls, and will queue queries when the concurrency limit is hit.

Just curious why? Athena has its own way of queueing, and would not fail the queries either.

Thanks!

maybe it is for keeping alive a line of super long queries that would take more than 30 minutes, which is the AWS athena default timeout?

I thought that errors will be returned from aws sdk when the service limit is exceeded.

https://docs.aws.amazon.com/athena/latest/ug/service-limits.html

Is there documentation about Athena queuing query?

seems that the concurrency limit is per server? what if I have 100 servers running your library?
