Hi Jaeho, I was trying to update the interface as well as the incremental ddlog program to reflect recent ddlog changes. Since #376 updates ddlog, I think it would be better if #376 is reviewed and I base this work on top of it.

@feiranwang Sorry I wasn't clear about my intention. I was postponing the merge because it was modifying the docs that may conflict with other more urgent issues. It looks good so please base your commits on top of #376.

@netj Sounds good. Thanks!

@netj Is anyone doing the pass of documentation here? I can still see grammatical errors in that page (I am happy to do one pass if no one is doing this)

@zhangce The doc is updated in incremental_update branch. I'm updating the interface while running experiments...
