Hey!
I'm trying to import data from google sheets into a big query table. I used the URL method and I was able to get the data. But it looks like I'm not able to store the metadata and because of this, I can't use this table with any analytical tool like ThoughtSpot. Is there a workaround for this? How can I get data from Google Sheets onto big query and then use that table elsewhere?
Basically, I think I need to enable metadata caching, how do I do that?
Thank you in advance 😄
You're right in focusing on the importance of metadata for using BigQuery tables with analytical tools like ThoughtSpot. However, the concept of "metadata caching" as you described doesn't apply in the context of BigQuery. Instead, BigQuery automatically manages metadata, such as the table schema, as part of its standard functionality. Here's how you can effectively use data from Google Sheets in BigQuery and ensure compatibility with tools like ThoughtSpot:
Import Data from Google Sheets to BigQuery:
Schema and Metadata Management:
Integration with Analytical Tools:
Refreshing Data from Google Sheets:
Using External Tables (Optional):
Testing and Validation:
In summary, focus on ensuring that your BigQuery table's schema correctly represents your data and that ThoughtSpot is properly configured to read this schema. BigQuery handles metadata management automatically, so there's no need for a separate metadata caching mechanism.
I am having the same issue and question. I also use ThoughtSpot and have directly linked the google sheet into google big query and linked ThoughtSpot to google big query. This does work but the issue is the loading time of ThoughtSpot now. I worked with the tech team at ThoughtSpot and found that I had to create a copy table in the data set and then insert the table from the connect google sheet into the new copy table I created. This did solve my speed and time out issues. Yet now each week when we get data from our clients I need to delete the copy and recopy the table and re insert the data from the new data that came in that week. Also this was working until now I am trying that process again and now Google Big Query is not loading all of the data from the insert. The data is not matching from the google sheet table to the copy table i have made. So I had to reconnect the original table that is connected to the google sheet back to ThoughtSpot and now having speed and time out issues again. Is there a way to create a better cach on the table that the google sheet is connected to?
Performance issues commonly arise when utilizing ThoughtSpot with a direct connection to a Google Sheet via BigQuery. These issues stem from the inherent limitations of real-time data synchronization. BigQuery's external data sources, including Google Sheets, are not designed for high-performance querying with large datasets or frequent updates. This can lead to resource strain and potential timeouts.
Current Approach and Its Limitations
The current approach of creating a copy table in BigQuery and manually updating it from the Google Sheets-linked table effectively reduces the load on BigQuery, thereby improving performance. However, this manual process can be time-consuming and tedious.
Proposed Solution: Automated Data Transfer with Google Cloud Functions (GCF)
To address the limitations of manual data transfer, a more efficient solution is to automate the process using a scheduled data pipeline, specifically through Google Cloud Functions (GCF). This automated approach eliminates manual intervention and ensures regular data updates.
Steps to Implement Automated Data Transfer
Create a GCF Function:
a. Develop a GCF function that performs the following tasks:
i. Fetches the latest data from the Google Sheet using the Google Sheets API.
ii. Transforms the data to match the BigQuery schema.
iii. Inserts the transformed data into the BigQuery copy table.
Schedule the GCF Function:
a. Utilize Cloud Scheduler to trigger the GCF function at a regular interval (daily, weekly, etc.) that aligns with your data update schedule.
Configure ThoughtSpot:
a. Connect ThoughtSpot to the BigQuery copy table. This ensures ThoughtSpot utilizes the most up-to-date data, which is refreshed regularly by the GCF function.
Additional Points to Consider
Verify that the data transformation in the GCF function accurately reflects the schema required by ThoughtSpot.
Implement error handling and logging within the GCF function for effective management and troubleshooting.
Conduct thorough testing of the entire pipeline to confirm data integrity and the expected performance improvements.
Benefits of Automated Data Transfer
Eliminates manual intervention and ensures regular data updates.
Reduces strain on BigQuery, improving performance for both ThoughtSpot and other BigQuery users.
Maintains a synchronized and efficient data flow between Google Sheets and BigQuery.
By adopting this automated approach using Google Cloud Functions, you can effectively optimize ThoughtSpot's performance when utilizing data from Google Sheets via BigQuery. This solution eliminates manual data transfer, improves performance, and ensures data consistency.
Is there an video or step by step instructions I can view to build this on my own? I am best when I learn by watching and then doing.

How to trigger the GCF when the Google Sheet is edited ?
To trigger a Google Cloud Function (GCF) when a Google Sheet is edited, you can use Google Apps Script to create a trigger within the sheet that calls the Cloud Function. Here's are some steps you take:
Step 1: Create the Cloud Function
First, ensure your Cloud Function is set up to handle requests:
Step 2: Enable Google Sheets API
Make sure that the Google Sheets API is enabled in your Google Cloud project:
Step 3: Create Google Apps Script
Use Google Apps Script to add a script to your Google Sheet that will trigger your Cloud Function when edits are made:
function onEdit(e) {
var url = 'YOUR_CLOUD_FUNCTION_URL'; // Replace with your Cloud Function URL
var options = {
'method' : 'post',
'contentType': 'application/json',
'payload' : JSON.stringify(e),
'muteHttpExceptions': true
};
try {
var response = UrlFetchApp.fetch(url, options);
Logger.log(response.getContentText());
} catch (error) {
Logger.log('Failed to trigger Cloud Function: ' + error.toString());
}
}
Step 4: Deploy the Script as a Trigger
