The article suggest adopting the right solution, Flink, for big data processing. Flink is interesting and built for stream processing. The broader view and take away may be to solve problems using the right solution. We saw many painful…
The public cloud storage services like Amazon S3, Google Cloud Storage and Windows Azure Storage replicate the data to ensure high availability. On the other hand, with data being replicated, the storage services exhibits certain data consistency models. Different cloud service providers employ different data consistency models nowadays. In this post, we survey the data…
Temporary forks and chain reorganizations (reorgs) are natural occurrences in decentralized blockchain systems. They arise due to the asynchronous nature of block propagation across the network. While temporary forks are short-lived and resolved quickly, chain reorganization refers to the process by which the blockchain discards one branch in favor of a longer or higher-priority chain….
Paxos and Raft are both consensus algorithms used to ensure consistency in distributed systems. While they solve similar problems, they have different approaches and design philosophies. Characteristics Paxos Roles: Proposers, Acceptors, Learners. Phases: Two main phases (Prepare/Promise and Propose/Accept). Leader Election: Not explicitly defined, often implemented using Multi-Paxos to handle multiple proposals efficiently. Use Cases:…
Cryptocurrency exchanges have revolutionized the way we trade digital assets, with two main types of exchanges dominating the market: decentralized exchanges (DEX) and centralized exchanges (CEX). In this article, we’ll compare the DEX and CEX from a technical perspective. Decentralized Exchanges (DEX) DEX operate on a decentralized blockchain network, such as Ethereum, and are built…
Amazon S3 is a widely used public cloud storage system. S3 allows an object/file to be up to 5TB which is enough for most applications. The AWS Management Console provides a Web-based interface for users to upload and manage files in S3 buckets. However, uploading a large files that is 100s of GB is not…
