How should the company perform this data load?
Use an AWS SDK with a multipart upload to transfer the data from on premises to the S3 bucket. Use the Copy command for Neptune to move the data in bulk from the S3 bucket to the Neptune DB instance.
Use AWS Database Migration Service (AWS DMS) to transfer the data from on premises to the S3 bucket. Use the Loader command for Neptune to move the data in bulk from the S3 bucket to the Neptune DB instance.
Use AWS DataSync to transfer the data from on premises to the S3 bucket. Use the Loader command for Neptune to move the data in bulk from the S3 bucket to the Neptune DB instance.
Use the AWS CLI to transfer the data from on premises to the S3 bucket. Use the Copy command for Neptune to move the data in bulk from the S3 bucket to the Neptune DB instance.
Explanations:
While the AWS SDK and multipart upload can be used to transfer data to S3, the Copy command is not supported for bulk data transfers to Neptune. The Copy command is specific to Amazon Redshift.
AWS Database Migration Service (DMS) is not designed for bulk data transfers to S3 or Neptune. DMS is primarily used for database migration, not for transferring files directly to S3.
AWS DataSync is an efficient, high-performance data transfer tool for moving large datasets to S3. The Loader command in Neptune is specifically designed to bulk load data from S3 into Neptune.
The AWS CLI can transfer data to S3, but the Copy command is not applicable for Neptune. It is used for bulk loading data into Redshift, not Neptune.
I rank that the answer is:
Use AWS DataSync to transfer the data from on premises to the S3 bucket. Use the Loader command for Neptune to move the data in bulk from the S3 bucket to the Neptune DB instance.
