My two cents Honestly when I found BookKeeper I was very happy because I found an "original" building block to build replicated state machines. I think that the main soul of BK is exactly to be a WAL and this is really "original". >From my point of view the "key features" of BookKeeper are "Fencing" and "Last-Add-Confirmed protocol" BookKeeper is really good at storing data, but IMHO it is because it has been designed and implemented by very skilled engineers, BookKeeper needs to be "fast", because in order to provide a fast WAL you have to give an ultra-fast storage, because the essence of a WAL is "durability" and usually "durable" comes together with 'sync' and so with 'slow' . I am not a "marketing expert" but IMHO we should stress on the distinctive features of BK in respect to other softwares. I am not against the proposed change but as an user I wanted to point that I happy with BK because it is the most powerful distributed WAL (and maybe it is the unique in the opensource/free world) I would like to write in the website that BookKeeper is the real answer to whom who are looking for a distributed WAL. -- Enrico > > [1] > https://www.slideshare.net/hustlmsp/apache-bookkeeper-a-high-performance-and-low-latency-storage-service > [2] https://www.slideshare.net/jujjuri/apache-con2016final
