You can also specify an S3 prefix and namespace to organize your data in the S3 bucket.

If you're using Role-Based Authentication, you can use the RudderStack IAM role for authentication. If not, you'll need to enter the AWS Access Key ID and AWS Secret Access Key to authorize RudderStack to write to your S3 bucket.

Finally, you can configure the sync frequency and starting time for RudderStack to sync the data to your S3 data lake.

When choosing a name for your S3 bucket, consider using lowercase letters. This will help keep your naming convention consistent.

A well-structured name can greatly simplify data retrieval and management. Use numbers, hyphens, and periods to create a clear and organized name.

Avoid using spaces and underscores in your bucket name, as they can cause confusion. For example, company-data-lake is a better choice than Company_Data_Lake.

A consistent naming convention is essential for efficient data management. It makes it easier to find and access the data you need.

Data ingestion involves collecting raw data from various sources and bringing it into the data lake. Amazon S3 supports multiple ingestion methods, including batch processing and real-time streaming.
