Abstract: The present disclosure provides for a system with an adaptive thread pool for processing messages. The system includes a processor and a memory storing instructions. The processor allocates a first quantity of threads in a thread pool to process a set of messages in parallel. The processor then measures one or more performance metrics of the system while processing the messages with the first quantity of threads. The processor then determines whether each of the one or more performance metrics meets a respective predetermined threshold. The processor then increases the allocation of the first quantity of threads to a second quantity of threads in the thread pool if each of the one or more performance metrics meets the respective predetermined threshold. The processor may also decrease the quantity of threads if at least one performance metric does not meet its predetermined threshold.
