I am getting issues when using the write file connector with option “Append” on Azure. It says it is not supported.

Therefor I’m trying to change this into the other option which is correct. But based on the docs I do not understand what the append option is doing. On the docs it just says “ Append file disk_write_mode_append - There must be a file present at the specified location, this will be extended. This is not really telling my anything. So, it only works when files already exist, if it's a new file it will do nothing?

Next to this, does Azure not support this feature or does indicium not (yet) support this feature for Azure?

The disk_write_mode_append is not supported by the write file connector, the documentation is incorrect at this point.

This causes the process action to fall back to the default write mode, which creates a new, unique file name if the provided file name already exists.
