I am installed and added data source (web data connector) inside tableau
Web data connector URL : http://localhost/datasouceexample/example.html
we data connector holds some data.
import data from web data connector and created graphs using the data's from the web data connector URL .Generated graph and saved in "tableau public" option.
Embed the code inside my web application . Graphs shows perfectly.
My question is about the automatic data updation .
1 ) I want to update graph automatically based on the value from web data connector URL
2 ) If any new updations are inside input datas (new inputs) , automatically sync with tableau and update the graph,so no changes in the embed code and graph updated automatically
Any settings available inside tableau for do this section? if it is possible ? Thanks
Only dashboards with a google sheets datasource can be automatically updated on Tableau Public. Maybe you could redesign your web service to write to a google sheets doc. If so, you could republish your dashboard to sync with that doc.
The scenario you are describing is not possible using Tableau Public (the free version of Tableau software) and the web data connector. Tableau Public does not support updating web data connector data once published on Public, you would need to refresh the data from your desktop application and republish.
The closest supported path to your use case would be, as Kara_F mentioned in the comments, to use Tableau Server. With that product, you can create web data connector datasources and publish them to your Server. You can then schedule a refresh job which will update your data at a certain interval. More info for keeping WDC data up to date can be found here: http://onlinehelp.tableau.com/v0.0/server/en-us/datasource_wdc.htm.

Using custom connector i am able to load data from mysql to s3 in AWS Appflow but when creating a new table in mysql, it is not showing up in Appflow console.
New entities are discovered during the ListEnties event that is called recursively when building a flow amd selecting the source object. Since you are building a custom connector all the logic of how the connector discovers entities is in your custom code. Specifically the list_entities method of your MetadataHandler.
See the end-to-end flow of the readme of the Python custom connector SDK. I quote part here.
https://github.com/awslabs/aws-appflow-custom-connector-python
Step 5: AppFlow user then uses that ConnectorProfile to create Flow definitions. During the flow creation AppFlow invokes listEntity and describeEntity functions on the connector to retrieve the list of supported entities and the entity detail of the specific entity AppFlow user selected on the console / API.
With that said, if you can share im your question the code of your metadata handler as well as a description of the source database and why you think the new table should be discovered by your code.
I would also look at the CloudWatch logs or whereever you store logs for the Lambda hosting your custom connector. View the logs after trying to build a flow and not seeing the expected new entities listed. If there is an error trying to read a new entitiy you could see it here if you have the proper logging setup.
I have few custom modules created using Module Builder. I need to fetch data using external REST API (around 200-300k record per API) and without storing data in suite database I need to display data on custom modules (using UI provided by SuiteCRM only. NO CUSTOM UI). and also I have operations to be perform on data which will again call External API.
So, as per requirement, Data should not be saved at database. How to achieve this in SUITECRM (7.11.8 version)?
I have tried using Process record hook. But things aren't working.
I have existing Tableu Server workbook with diagrams and own datasources(mysql).
Is it possible to fetch data from Tableau Server via Rest Api, e.g. if I build a custom web dashboard and need only data from Tableau?
I am interested in Tableaus ability to filter/aggregate data, thats what it does for its diagrams, would be great to harvest it from custom Python web page for my custom diagrams (e.g. for D3 or Highcharts).
Is "Extracts API" the right direction for this?
Or the path with "Query View Data" is the solution?
If you want to specify the filter values and get the exact set of data that your diagrams/workbooks are using, go with the Query View Data solution.
If you pull the data from the extract, you will get it exactly as it is out of the extract. This means if you have filters or aggregation done in your visualization (which is processed after the extract), it won't apply to the extracted data.
My company recently transitioned to IBM Connections and has closed down a few features like Box.com.
IBM Connections can also store files, but when uploading them, I cannot connect Tableau to them directly as the file path is a URL and Tableau cannot get files from URLs.
I've tried to load it in Power Query and then load it in Tableau but then I need to find a way to refresh the file while the original Excel file gets edited.
Any suggestions how can I get a live connection from IBM Connections Docs > Tableau Server?
I don't believe a live connection is possible. However, it looks like IBM provides a robust api. Depending on your requirements, you could script something that writes out a json file. Then use tableau to refresh the json as an extract on a schedule. Another possibility is the Web Data Connector.
I would like to use a REST API as a data source for tableau. Is this possible in any way? The API service returns standard JSON, and I would think that would be an ideal scenario for tableau. Rather than connecting to some backend database behind the API.
Thanks
The web data connector does this and is in beta right now as noted by inox. See: https://www.tableau.com/web-data-connector
"The Web Data Connector will allow you to create a connection to almost any data that is accessible over HTTP. This can include internal web services, JSON data, REST APIs, and many other sources. It will not be supported in the initial launch of Tableau 9.0. Beta participants will be able to use a dedicated product key to continue building and testing connectors until the Web Data Connector officially launches."
Also, you can use the Extract API to create Tableau Extracts from an API: https://www.tableau.com/learn/tutorials/on-demand/extract-api-introduction
