@Charlie You​ :

The error message you're encountering suggests a timeout issue when reading from the Delta-shared dataset hosted in S3. There are a few potential reasons and solutions you can explore:

1. Network connectivity: Verify that the network connectivity between your GCP workspace and the S3 bucket hosting the Delta-shared dataset is stable
2. Access credentials: Confirm that the GCP workspace has the necessary access credentials or permissions to read from the S3 bucket
3. Dataset size and performance: If the Delta-shared dataset is large or contains a significant amount of data, the read operation may take longer and potentially exceed the default timeout settings
4. Spark configuration: Review the Spark configuration in your GCP workspace and ensure it is optimized for handling the size and complexity of the Delta-shared dataset
