Building a Real-Time Analytics Database: a Choose Your Own Adventure Journey

Big Data & AI

Have you ever stopped to think about how to build a database? The thing is, there isn't just one way, as we can see by the massive number of data infrastructure options we have to choose from. It's a nonstop series of tradeoffs, each motivated by the constraints the database wants to satisfy. An in-memory transactional database would be one thing. A general-purpose, single-server relational database would be another. A low-latency, horizontally scalable analytics database would be...the journey we're going to take.

In this talk, we'll start by picking a data model, make decisions about serialization and storage, choose indexing strategies, pick a query language, and figure out how to scale, eventually ending up with something that looks remarkably like Apache Pinot, a real-time analytics database. Pinot was built on a journey like this, always optimized for ultra low-latency, user-facing analytics at scale. In the real world, Pinot is used by applications like LinkedIn and UberEats to expose the state of the system not just to internal decision-makers, but to the users of the system itself, including all of us people who consumers of analytical queries. By focusing on the internals of Pinot and the tradeoffs made along the way to build a database of its kind, we'll see how it enables a new class of applications that every user of a system into a decision maker.

Introducing Apache Pinot

Big Data & AI

When things get a little bit cheaper, we buy a little bit more of them. When things get cheaper by several orders of magnitude, you don't just see changes in the margins, but fundamental transformations in entire ecosystems. Apache Pinot is a driver of this kind of transformation in the world of real-time analytics.

Pinot is a real-time, distributed, user-facing analytics database. The rich set of indexing strategies makes it a perfect fit for running highly concurrent queries on multi-dimensional data, often with millisecond latency. It has out-of-the box integration with Apache Kafka, S3, Presto, HDFS, and more. And it's so much faster on typical analytics workloads that it is not just a marginally better data warehouse, but the cornerstone of the next revolution in analytics: systems that expose data not just to internal decision makers, but to customers using the system itself. Pinot helps expand the definition of a "decision-maker" not just down the org chart, but out of the organization to everyone who uses the system.

In this talk, you'll learn how Pinot is put together and why it performs the way it does. You'll leave knowing its architecture, how to query it, and why it's a critical infrastructure component in the modern data stack. This is a technology you're likely to need soon, so come to this talk for a jumpstart.
