# BenchFoundry will issue a prepare command to the database connector before sending the execute command
# at the poin in time specified in the trace. This property specifies the duration between prepare and
# execute command. Choosing high values will result in large thread pool sizes, choosing low values may
# cause delayed execution of transactions depending on the complexity of preparing transactions and the
# number of transactions per business process.
transactionPrepareTimeInMs:1000
# BenchFoundry will submit process instances to a thread pool for execution prior to the specified timestamp from
# the trace. This is done to assert on-time execution of the process. Choosing small values may lead to delay,
# high values may lead to significantly increased thread pool sizes.

#If this flag is set to true, then BenchFoundry will use a closed workload scheduler for the experiment phase.
