Due to the large amounts of data that could be passed to and from MemberPro to the new WST site, we would suggest using AJAX API calls with Promises, and Site Caching as much as possible. However, we realize the need for new, live data to be obtained whenever a user requests it. Eclipse360 and MemberPro will work together closely to cache data whenever it’s feasible to do so and to grab new data whenever it’s available.
eclipse360 is aware that the WST site must be timely (reduced latency) as riders may have just finished a run and all consumers of that data will be after the latest results within seconds of the run finishing. We propose that the site will prompt users whenever new information is available via a message at the top of the screen and, once refreshed, the latest data will be displayed.
We propose using a combination of AJAX Promises, Comet Cache for site-wide page caching, and a watch method (messaging as described above) to know when and which data points must be refreshed as quickly as possible.
We will also investigate whether or not header ETags would be useful or simply watching for database changes via a date/time stamp will suffice to refresh content utilizing 304 header responses.
Interestingly, datatables (as described on the Direction and Samples page) as of version 1.9.4 have the ability to cache server-side requests that the user makes to the database to dramatically reduce redraw times on client devices by utilizing client-side data caching, which will bypass the server-side API call. However, datatables also have the ability to clear the client-side cache in order to dynamically refresh the data.
Based on the size and complexity of the data to be displayed we could use a combination of any of the methods above in order to make the new WST as fast and dynamically data-rich as possible and page-specific datatables may use slightly different variations of these methodologies for rapid display purpose.
Naturally, all of this will be seamless from the consumer’s point of view; it will just work.
