Distributed Systems

To deliver consistency across various platforms — Saga is the most common pattern for ensuring cross-service data consistency. It splits a global transaction into multiple subtransactions. If all subtransaction operations succeed, then the global transaction succeeds, and if one subtransaction still fails after retries, then all executed subtransactions are compensated. The above process is simple and clear…

Not that long ago, we used to develop our applications to run standalone on a single machine and use as many resources as needed and available. But we needed to evolve to become more efficient in utilizing compute resources. Multi-tenancy became a standard. Experience tells us that good fences make…

This article is to compare and appreciate the marvellous engineering systems, their capability to push notification at scale having being designed at the big tech organisations of modern world: Uber and Netflix. There are quite a lot of similarities in their requirements and way that they have designed the systems…

Naive Bayes, birçok alanda sınıflandırma için kullanılan istatiksel bir metoddur. Bayes teoremine dayanan naif yani zayıflatılmış ve kolaylaştırılmış bayes demektir. Ana temeli bir olayın olasılıksal olarak gerçekleşme payını hesaplamaktır.Buradaki amaç baskın olan koşulu ortaya koymak ve onun sınıfını ayırmaktır. Tabi ki bütün bu bahsettiklerim Naive Bayes sınıflandırma içindir. Paralleştirme ise…

MapReduce programming model fundamentally changed the data processing world. The MapReduce pattern may be older, but Google’s MapReduce seminal paper and the Hadoop open-source distribution enabled programmers to run analysis on large data sets without having expertise in distributed servers and cluster management. Google published many such papers over some…
