You don't really need an ExecutorChannel - simply set ignoreFailures to true on the pub/sub channel...

/**
 * Specify whether failures for one or more of the handlers should be
 * ignored. By default this is <code>false</code> meaning that an Exception
 * will be thrown whenever a handler fails. To override this and suppress
 * Exceptions, set the value to <code>true</code>.
 * @param ignoreFailures true if failures should be ignored.
 */
public void setIgnoreFailures(boolean ignoreFailures) {

If you want to log or otherwise handle exceptions on the DB store, you can add an ExpressionEvaluatingRequesthandlerAdvice to the component that does the DB store.

If you really want an ExecutorChannel, the DSL section of the reference manual has an example.

.channel(MessageChannels.executor("executorChannel", this.taskExecutor))
