Delta: A highly available, strongly consistent storage service using chain replication

What this post added

Introduced Delta, a new object storage service designed for critical build and distribution artifacts, prioritizing high availability and strong consistency. Delta leverages chain replication for data redundancy and fault tolerance, trading latency and storage efficiency for simplicity and reliability. It supports basic operations (put, get, delete, list) and is horizontally scalable. The post details the architecture of Delta, its comparison with quorum replication, and its failure and recovery modes, including host failure detection and recovery mechanisms.
