All, I have created a new Page on the NiFi Wiki called 'NiFi Architecture' [1]. This page is under the 'For Developers' page. I have moved the Registry Design page under this page and have created two new pages: NiFi's Write-Ahead Log Implementation and Persistent Provenance Repository Design. These are basically just notes on the designs of these components, as they are two of the very critical parts of the architecture. Just wanted to let people know they are here, if anyone has interest in looking over them.
