# Using the default synchronous worker because:
# 1) Asynchronous workers are difficult to configure correctly, and our usage
#    is low enough that the risks out weight the benefits
# 2) We want to use Sentry to profile the API and profiling breaks with greenlets
#    (https://greenlet.readthedocs.io/en/latest/tracing.html)
# Using 2 workers to minimize number of different connection pools and reduce memory usage
