What the research is: The continued emergence of large social network applications has introduced a scale of data and query volume that challenges the limits of existing data stores. However, few benchmarks accurately simulate these request patterns, leaving researchers in short supply of tools to evaluate and improve upon these systems.  To address this issue,… Continue reading Open-sourcing TAOBench: An end-to-end social network benchmark

Meta’s overall network usage and traffic volume has increased as we’ve continued to add new services. Due to the scarcity of fiber resources, we’re developing an explicit resource reservation framework to effectively plan, manage, and operate the shared consumption of network bandwidth, which will help us keep up with demand and limit network disruptions during… Continue reading Network Entitlement: A contract-based network sharing solution

Meta currently operates 14 data centers around the world. This rapidly expanding global data center footprint poses new challenges for service owners and for our infrastructure management systems. Systems like Twine, which we use to scale cluster management, and RAS, which handles perpetual region-wide resource allocation, have provided the abstractions and automation necessary for service… Continue reading Viewing the world as a computer: Global capacity management

Meta is introducing Velox, an open source unified execution engine aimed at accelerating data management systems and streamlining their development. Velox is under active development. Experimental results from our paper published at the International Conference on Very Large Data Bases (VLDB) 2022 show how Velox improves efficiency and consistency in data management systems. Velox helps… Continue reading Introducing Velox: An open source unified execution engine

At Salesforce we regularly use our products and services to scale our own business. One example is Buildpacks, which we created nearly a decade ago and is now a part of Hyperforce. Hyperpacks are an innovative new way of using Cloud Native Buildpacks (CNB) to manage our public cloud infrastructure.  Buildpacks were created to help… Continue reading Hyperpacks: Using Buildpacks to Build Hyperforce

When we focus on minimizing errors and downtime here at Meta, we place a lot of attention on service-level indicators (SLIs) and service-level objectives (SLOs). Consider Instagram, for example. There, SLIs represent metrics from different product surfaces, like the volume of error response codes to certain endpoints, or the number of successful media uploads. Based… Continue reading Improving Meta’s SLO workflows with data annotations
