Abstract For critical distributed systems, data durability is the ultimate operational baseline. However, at extreme scales, handling millions of OLTP operations per second across petabyte-sized datasets, traditional backup strategies often become the very bottleneck they were designed to prevent. more

Abstract In highly coordinated distributed systems like Apache HBase, operations often rely on global barriers, synchronized procedures that require every node to reach a consensus point before moving forward. At extreme scales, these barriers become highly sensitive to thread contention and coordination overhead. This talk details a real-world production incident at Flipkart where a critical dis… more
