Any luck yet?
I'm using SSIS to ALTER VIEW and tabonlinsyncclient.exe to incrementally refresh and append it to tableau online. I've been able to append hundreds of millions of rows this way.
But sometimes there are errors, so I'm looking for alternative methods of automating TDE updates.
1) I've got a big tde on tableau online
2) I can manually create new tde's on my c: drive from my tds (connected to my sqlsvr view)
3) Then I can easily use tabcmd to append them to my big tableau onlne extract.
(Note: my source data is not a csv, and my tds contains lots of curation I've performed on it, so my tde updates must come from my tds structure.)
The question is for step 2: how do I use my tds to generate the local c: drive tde without manually doing so with the tableau desktop UI ? In other words, how do I automate the generation or full-refresh of a local tde file on my c: or unc path ?
I'd love to say yes, but that would be too much - I'm still midway in the
What worries me the most are the calculated fields, bins and sets. I'm not
yet sure whether I can recreate those from *.tde, and most importantly -
how to automate the process of creation.
The rest of the process is not a problem - I'm using Kettle (Pentaho data
integration) with pre-enabled Tableau Data Extract Output feature (check
that out, it's awesome), I'm just worried about creating the right set of
columns earlier in the transformation and whether the sets and bins will
still be there.
Another issue I have is that simple appending won't do the job alone. It is
an often situation that some of the records that were previously in the
data source shouldn't be there after the refresh. Sometimes I add
additional columns to my TDE and want them to be populated for all the rows
that were already in the TDE.
I'm just looking for a way to make sure that sets, bins and calc fields
will still be there, unchanged, after an extract is made. Basically, I need
a way to dynamically read that metadata info and recreate the TDE locally
using TableauExtractAPI. If anyone finds a way to do that, it would solve
many problems! (heads up for devs, make that happen )
I believe that it is already possible, I just can't find any useful info in
TableauExtractAPI documentation. Hope somebody will answer our questions

Stephen Hicks,so this is what I've came up with:
Since my extracts are generated from DB Views, my idea is to create some kind of "templates" of TDEs with zero rows but correct metadata. Then store TDE and TDS to a *NIX server.
Extract SQL query from TDS and use it to pull data set from DW (same view, just not limited). After that append the rows to the template TDE and push full TDEs to Tableau Server.
Please reconsider this flow, I'm open for any flaws you may find in it.
