This writer sends data to a ThoughtSpot platform.
Create a new configuration of the ThoughtSpot writer. Then Set Up Credentials. You need to provide a host name, user name, password, database name, schema and SSH user and SSH password. The writer uses the TSLOAD CLI tool and TQL commands to load that data. These commands are executed on the server through an SSH connection. Therefore the SSH credentials are needed to connect to the server instance.
The next step is to configure the tables you want to write. Click the Add New Table button and select an existing table from Storage:
The next step is to specify table configuration. Click the Edit Columns button to configure the table columns:
Use the preview icon to peek at the column contents.
For each column you can specify its
IGNOREmeans that the column will not be present in the destination table.
When done configuring the columns, don’t forget to Save the settings.
At the top of the page, you can specify the target table type and name additional load options. The table type is
DIMENSION. See an explanatory article
about schema design or the official guide for
more details on designing the data schema.
There are two main options how the writer can write data to tables — Full Load mode and Incremental Load mode.
In the Incremental Load mode, the data are bulk inserted into the destination table and the table structure must match (including the data types). That means the structure of the target table will not be modified. If the target table doesn’t exist, it will be created. If a primary key is defined on the table, the data is upserted. If no primary key is defined, the data is inserted.
In the Full Load mode, the table is completely overwritten including the table structure. The table is removed
DROP command and recreated.
Additionally, you can specify a Primary key of the table, a simple column data filter, and a filter for incremental processing.
