Example 1 with HandlerProxy

use of com.nearinfinity.honeycomb.mysql.HandlerProxy in project honeycomb by altamiracorp.

the class ITUtils method startProxyActionConcurrently.

/**
     * Start concurrency number of actions concurrently and at the same time.  This
     * method ensures that the actions are started at the same time, and they are
     * not being blocked in a thread pool.  Obviously, this uses concurrency
     * number of threads simultaneously so use caution as thread starvation
     * deadlock can occur with high concurrency levels.
     *
     * @param concurrency Number of handler proxies to run the action against, concurrently
     * @param setup Action to be run on each proxy before starting concurrent actions
     * @param action Action to be run concurrently and in sync with other proxies
     * @param cleanup Action to be run to cleanup proxy
     * @param factory HandlerProxyFactory to supply proxies to be run concurrently
     * @throws InterruptedException
