Invocation concurrency: The number of threads of execution concurrently invoking a service or method.
调用并发性：并发调用服务或方法时执行的线程数。
The complexity in concurrency programming stems from the fact Threads often needs to operate on the common data. Each Thread has its own sequence of execution, but accesses common data.
并发的复杂性在于，线程需要经常访问共同数据，每个线程都有自己的执行顺序，但需要访问共同数据。
But getting used to this new model of execution can be a bit awkward, if only because it represents an entirely different way of thinking about concurrency.
但是，习惯这种新的执行模型可能有点儿困难，因为这是一种全新的并发性考虑方式。
Robust concurrency and asynchronous execution support.
健壮的并发和同步执行支持。
The pool grows as per the application demands for concurrency, and the threads that have finished execution are returned to the pool.
这个池依应用程序对并行的需求而增长，并且那些已完成执行的线程会被返回到这个池。
The retry is used in case a concurrency exception does occur in the query table execution and the query table engine needs to retry the claim operation.
重试仅用于查询表执行时出现并发异常且查询表需要重新申明的情况下。
Concurrency: tracks execution data to help find waiting threads in multi-threaded applications.
并发性：跟踪执行的数据以便在多线程应用程序中找到等待线程。
This paper studies the model of transaction execution and presents real-time validation concurrency control protocol(RTVCC)for RTADBSs.
该文研究了实时主动数据库事务执行模式，提出了有效性检查并发控制协议。
Is it a question of proper tools, such as better native support for concurrency in languages, or of execution frameworks?
如果有更好的工具可以解决问题么，比如在语言中加入对并发更好的本地支持，或者使用框架？
