1. The second approach is to use transport-level asynchrony.

2. But this approach doesn't use transport-level asynchrony.

3. In other words, asynchrony enables all remote operations except for the processing of returned data by the federated server to proceed concurrently.

4. In the figure below, asynchrony has been enabled, and the optimizer has chosen to place an ATQ operator above the rightmost (pink) SHIP.

5. Asynchrony should be explicit and non-transparent, but in a very lightweight and non-disruptive manner.

6. TSI can detect the ventricular systolic asynchrony in patients with uremic myocardiopathy and provide reliable parameters for clinical management.

7. These concurrent connections occur because of asynchrony and do not include connections from the query that were added because of some other optimization(e.g.

8. When asynchrony is used, often partners will embed their own correlation logic within their message protocol in order to coordinate which response correlates to which request.

9. This asynchrony can lead to significant improvements in query performance.http://

10. The asynchrony FIFO module can be applied in the other asynchrony interface circuit design in multi-clock system.

11. How much time is saved by the asynchrony in this plan?

12. In transport level asynchrony, separate transport connections are used for sending the request and receiving the response -- for example, when you use SMTP for transport.

13. Client-side asynchrony enables the request and response messages to be processed in two different threads.

14. Without asynchrony, the federated UNION operator initiates the blue leg first, waits for the remote join to complete, and retrieves its result set.

15. Early, accurate and reliable estimates of ventricular asynchrony may help to choose optimal candidates for cardiac resynchronization.

16. In addition, if the remote operations take approximately the same amount of time to return the first row, then the benefit achieved in enabling asynchrony is maximized.

17. The section thereafter summarizes the scope and impact of asynchrony in federated execution plans.

18. Unfortunately, this isn't good enough for many interaction schemes, as it precludes things like asynchrony, stateful interaction, and peer-to-peer communication.

19. Thus, the federated queries which benefit the most from asynchrony are those whose remote queries are complex and and for which it is time consuming to return the first row.

20. The bind and the prep options supply the default value for the CURRENT FEDERATED ASYNCHRONY special register.

21. Only SHIP operators with associated remote statements that appear in the plan tree underneath join or union operators are candidates for asynchrony.

22. It also provides the default value to the CURRENT FEDERATED ASYNCHRONY special register for dynamic SQL statements.

23. But queries that involve only nicknames have only very limited opportunities for such asynchrony 2.

24. If a dynamic statement is issued and the CURRENT FEDERATED ASYNCHRONY special register is set, the value of the special register is used to optimize the query.
