## Maximum number of thread in the thread pool
## Setting it to 0 or negative number will cause it to be set to #cores * 4
maxthreads int default=500

# The number of threads to keep in the pool, even if they are idle
corePoolSize int default=500

# The number of seconds that excess idle threads will wait for new tasks before terminating
keepAliveTime double default=5.0

## max queue size
## There can be queueSize + maxthreads requests inflight concurrently
## The container will start replying 503
## Negative value will cause it to set to maxthreads*4
queueSize int default=0

# The max time the container tolerates having no threads available before it shuts down to
# get out of a bad state. This should be set a bit higher than the expected max execution
# time of each request when in a state of overload, i.e about "worst case execution time*2"
maxThreadExecutionTimeSeconds int default=190

# Prefix for the name of the threads
