Limitations
This appendix provides a high-level list of limitations and issues. For additional details, refer to your vendor documentation.
Endpoint specific Constraints
Remote Path Endpoint
Operation
Limitation Description
Amazon-S3
Rename
Does not support renaming an Amazon-S3 folder.
Preserve file modification date
Does not support setting the file modification date to an Amazon-S3 object or file.
Append the file for Copy and Move
Does not support appending an object once an S3 object or a file is uploaded. This limits ActiveTransfer's support for resuming the transfer of the file from the point of interruption. This is applicable for Upload, Copy, and Move tasks.
Socks proxy
ActiveTransfer supports only HTTP and HTTPs proxy for Amazon-S3 endpoints.
Upload the batch of small files to Amazon-S3
Uploading a batch of small files takes a significant amount of time. This action is time-consuming as ActiveTransfer needs to initiate and then confirm each upload irrespective of the size of the file.
For events, it is recommended to use parallel processing for a large batch of small files which needs to be uploaded to the Amazon-S3 endpoint.
Unexpected behavior on unzip task with the compressed file in Amazon-S3
If the source for an Unzip task is a ZIP file that contains a large number of files, then it can lead to unexpected behavior. This occurs in the following scenarios:
*For the compressed file which contains a larger number of files.
*For an unzip task which takes beyond 5 minutes to unzip the files.
*If S3 closes the input stream from where ActiveTransfer reads the compressed files.
Delete a folder
Amazon-S3 does not support directory structure, hence it represents a directory using S3 keys and delimiter / symbol. If an S3 key contains a / symbol, then text till the delimiter is considered as a folder.
However, if there are multiple S3 keys with the same folder name, then to delete a folder ActiveTransfer must delete all S3 file objects that belong to that particular folder. This process is time-consuming.
If you attempt to delete a directory, then ActiveTransfer consumes time to list and delete the files of that particular directory.
AZURE-FILE
Rename
Does not support the Rename operations.
Preserve file modification date
Does not support setting the file modification date.
AZURE-BLOB
Rename
Does not support the Rename operations.
Preserve file modification date

Create directory
If you want to place a blob within a directory, thenActiveTransfer will maintain the hierarchy. However, you will not be able to create a directory explicitly without any files in it.
