Let's say I have two 100GB Perforce Streams: A and B. A is the parent B and only supports one-direction merging.
My goal is to setup regular automation to merge changes in Stream A down to Stream B. However, to do this, it looks like I have to create and sync the entire 100GB workspace for Stream B, then run a p4 integrate command to merge all the changes from Stream A, even if only a few files were changed in the parent! I can circumvent this sync issue slightly by using the same workspace after the initial sync, but this runs into scaling issues in terms of space and sync time as I add Stream C or D.
In sum: is there any way for me to create a workspace and create an integrate changelist such that I'm only syncing the minimal amount of files needed to create said integrate changelist, or am I out of luck?
