Hi,
I'm using the DBReplicator with PostgreSQL. Other than varchar, integer, and date data in my database I store some pictures as well. I noticed during the synchronization that my blob file increases in size which is reasonable since I have pictures replicate as well. However, after the synchronization is completed the blob file (located in ..\Replication\synchronize\client directory) does not get deleted nor emptied like zip and XML files . This causes the publisher/subscriber to zip the whole blob file next time when it tries to synchronize. So if the blob file is big it takes a lot of time to zip everything again and to send it over the network, especially if Real-Time synchronization is in place.

I suggest making the DBReplicator delete blob file automatically after it has been zipped and sent and the synchronization is completed successfully.
