Import Data

Load Data

You can bring data into Tableau from Singdata Lakehouse in several ways. Each method fits different needs. Some methods work best for small files, while others help you handle large or real-time data. Here is a table that shows the main options:

Method	Description
File upload from local computer	Upload data directly from your local machine into the Lakehouse explorer.
Copy tool in pipelines	Connect to many data sources and load data, either in the original format or as a Delta table.
Dataflows	Use Power BI dataflows to load data, with access to over 200 connectors in the Lakehouse explorer.
Notebook code	Use Spark libraries to connect to a data source, load data into a data frame, and save it in the lakehouse.
Stream real-time events	Stream real-time events using Eventstream to load data into the lakehouse.

You should pick the method that matches your project. For example, if you want to upload a small file, use the file upload option. If you need to move large amounts of data or use automation, try the copy tool in pipelines. Notebook code works well for advanced users who want to write code. Streaming real-time events helps when you need live data.

After you load your data into the Lakehouse, you can see it in Tableau. You can now start building your visualizations.

Build Visualizations

When you build dashboards in Tableau, you want them to be clear and helpful. Good dashboards help people understand data quickly. Here are some best practices you can follow:

Know your purpose and audience. Think about what you want to show and who will use the dashboard.
Place the most important view in the upper-left corner. People look there first.
Design your dashboard for the size it will be viewed at. Make sure it looks good on all devices.
Limit the number of views to two or three. Too many views can make things confusing and slow.
Add interactivity. Use filters and highlights so users can explore the data themselves.

Tip: Simple dashboards often work better than complex ones. Focus on what matters most to your audience.

You can now use your imported data to create charts, maps, and tables. Try different visualizations to find the best way to share your insights.

Troubleshooting

When you use Tableau with Singdata Lakehouse, you might have problems. This part helps you fix the most common ones so you can keep working.

Connection Errors

Connection errors happen if Tableau cannot reach the Lakehouse. These problems often come from network issues, wrong server names, or blocked ports. Here are some things you can do:

Check your internet. Make sure your device can reach the Lakehouse server.
Make sure the server name and port are right. Even a small mistake can stop the connection.
Ask your network team if firewalls or security settings block the connection.
Restart Tableau and try again.

If you still get errors, write down the exact message. This helps your admin or support team find the problem faster.

Authentication Issues

Authentication problems can stop you from logging in or seeing data. You might use Kerberos, OAuth, or single sign-on to log in. Each way has its own setup steps. Common problems include:

Wrong username or password.
Issues with Kerberos, OAuth, or single sign-on settings.
Proxy servers or load balancers set up wrong, which can block trusted authentication.

To fix these problems:

Double-check your login details.
Look at your authentication method settings.
If you use a proxy or load balancer, check the guides for these tools.
Turn on debug logging in Tableau to get more details about the error.

Tip: If you cannot fix the problem, share the debug logs with your IT team. This makes it easier to find and fix the issue.

Performance Tips

Sometimes, dashboards or queries run slow. Slow speed can happen for many reasons, like bad queries or big data sets. Try these tips to make things faster:

Use Tableau extracts to cut down on live queries.
Pause automatic updates while building dashboards. This saves time and lets you make changes without waiting.
Use the Apply button for filters. Tableau only runs queries when you finish setting all filters.
Design your tables well. Make data marts and group tables by important columns.
Use result caching. Tableau can reuse results from earlier queries.
If pagination is not supported, Tableau must load all results before you see them. This can slow things down.

Good design and smart settings help your dashboards run better and save money.
