The B圜onity team adopted elements common with other OLAP engines, including column-oriented storage, vectorized execution, MPP execution, and query optimization, according to Jaiswal. ![]() “This ensures that data is always up-to-date and eliminates any inconsistencies between read and write operations, guaranteeing data integrity and accuracy,” she wrote. This makes it suitable for running in the cloud.ī圜onity, which is developed in C++ (same as ClickHouse), delivers strong consistency of data read and write operations, Jaiswal wrote. “This transformation results in stateless computing nodes, enabling dynamic expansion and contraction by leveraging the scalability of distributed storage and the stateless nature of computing nodes,” Jaiswal wrote.Ī byproduct of the separation of compute and storage is multi-tenant resource isolation, which enables a single B圜onity implementation to be shared by multiple users without impacting performance. The core element separating B圜onity from its predecessor was the implementation of centralized data storage, which allowed for the separation of compute and storage nodes in the cluster. The company decided to upgrade the underlying architecture of ClickHouse and began the internal B圜onity project in 2020. “Since reading and writing operations were performed on the same node, they often interfered with each other, impacting overall performance.” “ClickHouse’s tightly coupled architecture led to interactions among multiple tenants in a shared cluster environment,” Jaiswal wrote. The main culprit, according to a May 24 blog post by B圜onity maintainer Vini Jaiswal, was ClickHouse’s shared-nothing architecture, which prevented the company from scaling storage and compute independently and assuring high levels of query performance. When the TikTok app took off globally later that year, the volume of data flowing into ClickHouse skyrocketed, leading to growing pains with the data warehouse. ByteDance, which owns TikTok, implemented ClickHouse in 2018 to process batch and real-time data. Less than a year later, ByteDance merged Musical.ly with its similar service, called TikTok, and the result has since become one of world’s fastest-growing apps and a global cultural phenomenon.You might not yet be a major TikTok influencer, but you can still analyze data like TikTok’s parent company, ByteDance, which recently released its real-time data warehouse architecture as open source.ī圜onity, the name of ByteDance’s data warehouse, is an elastically scalable, column-oriented relational database that’s based on ClickHouse, the scalable, open-source database that the Russian media giant Yandex created in 2009 and spun out into its own company in 2021. ![]() ByteDance said it would keep Musical.ly separate from its family of Chinese apps. At the time, Musical.ly, an app popular with teenagers to make homemade karaoke videos, had about 60 million users in the United States and Europe. The move is the latest in a back and forth between the United States and China, which are enmeshed in a global competition for technological dominance that has begun to cleave the high-tech world in two and start what some analysts refer to as a new Cold War.īyteDance, a seven-year-old company based in Beijing, acquired Musical.ly in November 2017 for $800 million to $1 billion. One of the people said that the American government had evidence of the app sending data to China. ![]() The Committee on Foreign Investment in the United States, a federal panel that reviews foreign acquisitions of American firms on national-security grounds, is now reviewing the two-year-old deal after lawmakers raised concerns about TikTok’s growing influence in the United States, said the people, who spoke on the condition of anonymity because the investigation was confidential. ![]() The United States government has opened a national security review of a Chinese company’s acquisition of the American company that became TikTok, the hugely popular short-form video app, according to people briefed on the inquiry.
