Clarification on Bulk Upload Process and Limitations for PCA S3 Buckets

[user-apv12]

We have multiple Bulk Upload Buckets created by the Post Call Analytics (PCA) deployment in Amazon S3. Could you please confirm the correct procedure for performing a bulk upload into these buckets? Additionally, are there any limitations or best‑practice recommendations regarding the number of files or file sizes that can be uploaded at once to the PCA Bulk Upload Buckets?

Any update on the bulk upload procedure?

[user-apv12]

There is an update on the S3 bucket, one of the S3 buckets is being created through a CloudFormation stack for this bulk upload. Since the Step Function includes a bulk‑upload workflow option, could you please provide the updated steps for using this feature? Additionally, it would be helpful to understand any limitations, constraints, or best practices associated with using bulk upload through Step Functions.
Thanks in advance!
