The Admin and Server pages have been redesigned to show more info quicker. In list view the columns can be resized. In thumbnail view the grid dynamically resizes. You can hover over a thumbnail to see more info about visualization. The content search is better too:
Web authoring (even mobile) introduced by Tableau 8 Server. Change dimensions, measures, mark types, add filters, and use Show Me are all directly in a web browser and can be saved back to the server as a new workbook or if individual permissions allow, to the original workbook:
Subscribing to a workbook or worksheet will automatically notify about the dashboard or view updates to your email inbox. Subscriptions deliver image and link.
Tableau 8 Data Engine is more scalable now, it can be distributed between 2 nodes, 2nd instance of it now can be configured as Active, Synced and Available for reading if Tableau Router decided to use it (in addition Fail-over function as before)
Tableau 8 Server now supports Local Rendering, using graphic ability of local devices, modern browsers and HTML5. No-round-trip to server while rendering using latest versions of chrome 23+, Firefox 17+, Safari , IE 9+. Tableau 8 (both Server and Desktop, computing each view in Parallel. PDF files, generated by Tableau 8 up to 90% smaller and searchable. And Performance Recorder works on both Server and Desktop.Tableau 8 Server introducing Shared sessions allows more concurrency, more caching. Tableau 7 uses 1 session per viewer. Tableau 8 using one session per many viewers, as long as they do no change state of filters and don't do other altering interaction. If interaction happened, Tableau 8 will clone the session for appropriate Interactor and apply his/her changes to new session:
Finally Tableau getting API, 1st part of it I described in previous blog post about TDesktop - TDE API (C/C++, Python, Java on both Windows AND Linux!).For Web Development Tableau has now brand new JavaScript API to customize selection, filtering, triggers to events, custom toolbar, etc. Tableau 8 has own JavaScript API WorkBench, which can be used right from you browser:
TDE API allows to build own TDE on any machine with Python, C/C++ and Java (see 24:53 at http://www.tableausoftware.com/tcc12conf/videos/new-tableau-server-8 ). Additionally Server API (REST API) allows programmatically create/enable/suspend sites and add/remove users to sites.
In addition to Faster Uploads andPublishing Data Sources, users can Publish Filters as Set and User Filters. Data Sources can be Refreshed or Appended instead of republishing - all from Local Sources. Such Refreshes can scheduled using Windows Task Scheduler or other task scheduling software on client devices - this is a real TDE proliferation!
My wishlist for Tableau 8 Server: all Tableau Server processes needs to be 64-bit (and they still 32-bit, see it here: http://onlinehelp.tableausoftware.com/v7.0/server/en-us/processes.htm ; they are way overdue to be the 64-bit; Linux version of Tableau Server (Microsoft recently changed very unfavorably the way they charge users for each Client Access) is needed, I wish integration with R Library (Spotfire has it for years), I want Backgrounder Processes (mostly doing data extracts on server) will not consume core licenses etc…
And yes, I found in San Diego even more individuals who found the better way to spend their time compare with attending Tableau 2012 Customer Conference and I am not here to judge:
