Democratizing Stream Processing @ Netflix By Guil Pires , Mark Cho , Mingliang Liu , Sujay Jain Data powers much of what we do at Netflix. On the Data Platform team, we build the infrastructure used across the company to process data at scale. In our last blog post, we introduced “Data Mesh” — A Data Movement and Processing Platform. When a user wants to leverage Data Mesh to move and transform data, they start by creating a new Data Mesh pipeline.

The Initial Need Leading to CQRS The traditional CRUD (Create, Read, Update, Delete) pattern has been a mainstay in system architectures for many years. In CRUD, reading and writing operations are usually handled by the same data model and often by the same database schema. While this approach is straightforward and intuitive, it becomes less effective as systems scale and as requirements become more complex.

While I am heartened to hear that the Executive Order on AI uses the Defense Production Act to compel disclosure of various data from the development of large AI models, these disclosures do not go far enough.

When it comes to Citus, successfully building out and scaling a PostgreSQL cluster across multiple nodes and even across data centers can feel, at times, to be an art form because there are so many ways of building it out.

When a user logs on to this desktop/laptop or mobile, opens a browser, and types the name of a website, the browser displays the required information, and the user performs an action on the site. Have you ever wondered how computers retrieve this information and what happens in the background? It’s an underlying web application architecture that makes this process possible.

In the world of distributed systems, the likelihood of components failing or becoming unresponsive is higher compared to monolithic systems. Given the interdependence of microservices or modules in a distributed setup, the failure of one component can lead to cascading failures throughout the system, potentially causing the entire system to malfunction or shut down.

The growing challenge in modern IT environments is the exponential increase in log telemetry data, driven by the expansion of cloud-native, geographically distributed, container- and microservice-based architectures. Organizations need a more proactive approach to log management to tame this proliferation of cloud data. By following key log analytics and log management best practices, teams can get more business value from their data.

Sometimes, there is a need to update the table and index statistics manually using the ANALYZE TABLE command. Without going further into the reasons for such a need, I wanted to refresh this subject in terms of overhead related to running the command on production systems. However, the overhead discussed here is unrelated to the usual cost of diving into table rows to gather statistics, which we can control by setting the number of sample pages.
