Log Structured Protocols Inwards Delos (Sosp21)

where the "Virtual Consensus inwards Delos" newspaper finishes, and  talks well-nigh using Delos to build command airplane databases at Facebook. These are my notes from "Tango: Distributed Data Structures over a Shared Log" idea of writing to a shared log too replaying it to reconstruct/materialize country at the machines. This base of operations persuasion is extended alongside a layered state-machine approach to brand the mutual platform to a greater extent than flexible independently expandable. The newspaper thence reports results from Facebook scale implementation of this idea. 

There is enough of room at the bottom.) A takeaway for me hither is that log ingestion too replaying is non that costly at the cloud/datacenter environment. This thence affords us to role this uncomplicated principled approach to solve to a greater extent than pressing bottleneck problems, similar developer productivity, command airplane reliability, etc.

To my commentary above, Mahesh responded alongside this fantabulous point:

There’s too roughly broader betoken well-nigh “the log is the network”; systems are easier to empathise if nodes role a durable ordered autobus rather than RPCing each other willy-nilly.

I concur fully. Our labor should last to slash complexity, non to add together to it. 

Computing's inwardness challenge is how non to brand a mess of it. --Dijkstra
