Parallel Execution

The ParallelExecutor service allows a computation to occur in parallel.

It can be used in two ways. First, with an explicit Future:

Code Block
java java
Future<String> future = executor.invoke(new Invokable<String>() { ... });

...

Another alternative will return an object proxy, not a Future:

Code Block
java java
RSSFeed feed = executor.invoke(RSSFeed.class, new Invokable<RSSFeed>() { ... });

...

tapestry.thread-pool.queue-size

Since
since 5.3

The size of the task queue. When there are at least the core number of threads in the pool, tasks will be placed in the queue. If the queue is empty, more threads may be created (up to the maximum pool size). If the queue is full and all threads have been created, the task is rejected (and exception is thrown).

Defaults to 100.
