Old pattern powering modern tech

Append-only is one of the oldest properties of storage systems that despite its simplicity powers the most efficient and sophisticated modern technology – from databases to blockchains and consensus algorithms.

It’s natural to look for a complex solution when faced with a challenging problem, yet paradoxically the simplest solution not only follows Occam’s razor rule but also makes it easier to achieve optimal performance, scalability and maintenance properties. In this presentation, we’ll go through some of the append-only property history, reasons behind its power and examples of how modern systems leverage it to solve wide range of challenges in performance, distributed systems and other areas.
