Concord Systems

Concord Systems was a Brooklyn, New York stream-processing company founded in December 2014 by Alexander Gallego and Emilio Del Tesoro, and backed by Bloomberg Beta. It built a high-performance distributed stream processing framework written in C++ on top of Apache Mesos, aimed at letting application developers and data scientists write real-time streaming computations ("operators") in the language of their choice — Python, Ruby, Go, Java/Scala, Node.js or Haskell — with Kafka and Amazon Kinesis connectors and a CLI for deploying topologies. Akamai Technologies acquired the company in an all-cash transaction in September 2016 and folded the technology into its IoT edge data platform for real-time messaging and log processing. The company is discontinued: concord.io is parked and the documentation site is gone. Its interface was a Thrift-based operator driver API rather than an HTTP/REST API, so there is no OpenAPI or event surface to catalog; the surviving first-party developer artifacts are the github.com/concord organization and the client libraries still published on PyPI, RubyGems and pkg.go.dev.

Concord Systems is profiled on the APIs.io network. Tagged areas include Company, Stream Processing, Real Time, Data Processing, and Big Data.

Concord Systems’ developer surface includes CLI and 5 more developer resources.
