Cortico is a non-profit that builds audio tools to improve public dialogue. Allison King is an engineer at Cortico, and she joins the show to talk about the process of building audio applications.  One of these applications was a system for ingesting radio streams, transcribing the radio, and looking for duplicate information across the different

Datomic is a database system based on an append-only record keeping system. Datomic users can query the complete history of the database, and Datomic has ACID transactional support. The data within Datomic is stored in an underlying database system such as Cassandra or Postgres. The database is written in Clojure, and was co-authored by the

A high volume of data can contain a high volume of useful information. That fact is well understood by the software world. Unfortunately, it is not a simple process to surface useful information from this high volume of data. A human analyst needs to understand the business, formulate a question, and determine what metrics could

Physical places have a large amount of latent data. Pick any location on a map, and think about all of the questions you could ask about that location. What businesses are at that location? How many cars pass through it? What is the soil composition? How much is the land on that location worth? The

Lyft is a ridesharing company that generates a high volume of data every day.  This data includes ride history, pricing information, mapping, routing, and financial transactions. The data is stored across a variety of different databases, data lakes, and queueing systems, and is processed at scale in order to generate machine learning models, reports, and

GraphQL is a system that allows frontend engineers to make requests across multiple data sources using a simple query format. In GraphQL, a frontend developer does not have to worry about the request logic for individual backend services. The frontend developer only needs to know how to issue GraphQL requests from the client, and these

A data warehouse serves the purpose of providing low latency queries for high volumes of data. A data warehouse is often part of a data pipeline, which moves data through different areas of infrastructure in order to build applications such as machine learning models, dashboards, and reports. Modern data pipelines are often associated with the

At Airbnb, infrastructure management is standardized across the organization. Platform engineering teams build tools that allow the other teams throughout the organization to work more effectively. A platform engineering team handles problems such as continuous integration, observability, and service discovery. Other teams throughout a company use the tools that a platform engineering team builds. For

In a modern data platform, distributed streaming systems are used to read data coming off of an application in real-time. There are a wide variety of streaming systems, including Kafka Streams, Apache Samza, Apache Flink, Spark Streaming, and more.  When Eric Anderson joined the show back in 2016, he was working at Google on Google

Distributed stream processing frameworks are used to rapidly ingest and aggregate large volumes of incoming data. These frameworks often require the application developer to write imperative logic describing how that data should be processed.  For example, a high volume of clickstream data that is getting buffered to Kafka needs to have a stream processing system
