When using LogStream staging for replication in Qlik Replicate, the Staging folder is compressed and stored on the Qlik Replicate server itself. Here's the process:
A Log Stream Staging task is defined to replicate changes from the source endpoint to the Log Stream Staging folder1.
This task creates a "Staging" file in the Log Stream Staging folder, which contains the changes from the source database transaction log as a compressed binary file1.
The storage path for the streamed data, which includes the Staging folder, must be specified in the Log Stream target endpoint settings, and it is explicitly stated that this path should be located on the Replicate Server machine2.
Therefore, the correct answer isD. On the Qlik Replicate server, as the staging folder is located on the machine where Qlik Replicate server is running, and it is where the compressed staging files are stored12.
