Note icon false title As of Datameer v6.1 An option allows you to designate the owner for a an export file on the Tableau server. Choose between either the current Datameer owner of the connection or a specific owner on the Tableau server.
If the user of the Datameer connection isn't a Tableau Server admin, you can only choose the owner of the connection. If the user is later set as a Tableau Server admin, the option to change to a different Tableau owner is possible.
If the owner has been set to be a specific owner on the Tableau server and that owner is later deleted, the next time the export jobs runs, the radio button automatically reverts back to Use Owner from the Datameer connector on Tableau.
Anchor tde tde Note title As of Datameer v6.3 Export using the TDE (Tableau data extract) file format. TDE files are a local copy of a subset or the entirety of the data that you can use to share, work offline, and improve your database performance.
This feature is only supported for Datameer installations running on Linux.
Downloading data without an export job is not possible as a TDE but is supported as TDSX.
File type mapping
Column/wiki/spaces/DAS60/pages/4620163738 between Datameer and Tableau differ and are accounted for during export. The following is the list of data type conversions:
Datameer Data Field Type Tableau Data Field Type BIG_DECIMAL DOUBLE BIG_INTEGER LONG_INTEGER BOOLEAN BOOLEAN DATE DATETIME FLOAT DOUBLE INTEGER LONG_INTEGER LIST UNICODE_STRING STRING UNICODE_STRING When there is data overflow
- BIG_DECIMAL => DOUBLE => positive/negative infinity on overflow
- BIG_INTEGER => LONG_INTEGER => arithmetic exception => record dropped (or job aborted, based on your export job setting)
Note title As of Datameer v7.4 As of Datameer 7.4, export using the Tableau Hyper file format is supported and all Datameer versions above 7.4.7 will show the Hyper format.
(Note, however, that although Datameer allows the option, Tableau Server before v10.5. will not support the export into Hyper format. When export is created and triggered to an unsupported Tableau Server, ingest of the Hyper format file will be refused.)
- Preview the columns of the workbook to be included and choose how to handle invalid data.
- Choose when to run the export job. Export jobs can either be run manually, run each time the workbook in Datameer is calculated, or at specifically scheduled times.
Custom properties can be added in the the Advanced section section as well as logging specifications.
