Union:
Combine
data that have been split across multiple files or tables into a
single Tableau data source.
Note:
This Union Feature available only for Excel and Text based data
source.
When
to use this Union Feature?
For
example see above image. I have city wise bike trips data in files.
Each city data stored in single file. But I want to analyze this data
for all cities. Then you have to copy this data from each file and
prepare new file by combining all this data. Instead of doing this
you can directly combined this files using new Union feature in
tableau 9.3
Similarly
some times we will collect monthly data in separate files. In that
scenario also we can use Union feature all combine all months data
into single data source without using copy and paste.
Data
Grid:
Now
you can Sort the data in data preview pane. you can create the
calculated fields, Groups
and bins also.
Join:
When
you pivot data, Tableau creates new columns. Now you can join on
those columns and
use
these fields for new data integration and analysis.
Data
Connections:
Salesforce.com
OAuth Support:
Use
the familiar Salesforce.com sign-in experience to sign in to
Salesforce.com from Tableau Desktop, Tableau Online and Tableau
Server.
Initial
SQL Support:
Tableau
now passes initial SQL commands when connecting to Oracle, Pivotal
Greenplum, and Microsoft SQL Server to set session attributes.
Tableau
Parameters in Initial SQL:
You
can now include parameters in an initial SQL statement for a data
source. This enables new scenarios, like row-level security, where
users can only see the data they are authorized to see.
Kerberos
for Teradata and PostgreSQL:
Leverage
your IT investments in enterprise data security to create a seamless
single sign-on flow from Tableau all the way to your database.
Performance:
On-Demand
Connections:
See
your data faster. When viewing a published workbook, Tableau connects
only to the data sources that are required to display your view
instead of connecting to all data sources in the workbook.
External
Query Cache:
Workbook
load times and interactions are faster thanks to caching. When using
Tableau Data Server, the external query cache and in-memory query
caches are better synchronized.
Maps:
Tableau
added postal codes for 39 European countries, districts in India, and
US demographic data layers for 2016. We’ve also updated postal
codes for UK, France, Germany, and the US.
Forecasting:
Tableau
automatically selects the best season length to help you forecast odd
seasonal patterns and irregular time-series. You can also forecast
values ordered by an integer dimension.
Excluding
Totals for Color Encoding:
Separate
your totals, subtotals and grand totals by excluding them from
color-encoding.
Look
at above image. Before 9.3 version Tableau applying color to totals
also. So Dark color always for total of that table. All actual values
will look lighter.
But
in 9.3 Tableau excluding totals from color encoding. So easily we can
see the highest and lowest values with color indication.
Sheet
Colors:
Make
your worksheets easier to identify and group by adding color to
the
sheet
tabs in the sheet-sorter and filmstrip views.
Progressive
Dashboard Load:
Not
having to wait for the entire dashboard to load means you can start
analyzing your data sooner.
Publish
data source:
It’s
easier to publish, keep your data fresh, and stay connected
with
the new Publish Data Source flow.
Mobile

Tableau Server connection and signs you in to the last server you
used.
Tableau

unexpectedly run out of space. Tableau Server now lets you specify
disk-space thresholds that alert you when space runs low.
PostgreSQL
