Enfore single thread handling of parallel webservice calls

Hi,

Given an application that offers webservices using the RestServices module, how can it handle 1.000+ webservice calls per minute where each call does database lookups? The issue that I run into is that the PostgreSQL connection pool blows up.

The Queue module is not an option because it works async from the original process. So I want to enforce single threaded handling with some kind of queueing, but to prevent this burst of activity.

I look forward to your suggestion. Btw, this is still Mx 5.21.

Kind regard,

Paul
