Kafka Summit London 2019

Kafka Summit London 2019

As streaming platforms become central to data strategies, companies both small and large are re-thinking their architecture with real-time context at the forefront. Monoliths are evolving into Microservices. Datacenters are moving to the cloud. What was once a ‘batch’ mindset is quickly being replaced with stream processing as the demands of the business impose more and more real-time requirements on developers and architects.

This revolution is transforming industries.

What started at companies like LinkedIn, Uber, Netflix and Yelp has made its way to countless others in a variety of sectors. Today, thousands of companies across the globe build their businesses on top of Apache Kafka®. The developers responsible for this revolution need a place to share their experiences on this journey.

Kafka Summit is the premier event for data architects, engineers, devops professionals, and developers who want to learn about streaming data. It brings the Apache Kafka community together to share best practices, write code, and discuss the future of streaming technologies.

When: May 13-14, 2019
Where: Park Plaza Westminster Bridge London

Ludvig Sandman, SVP Product Engineering and Bruce Zulu, Sales Engineering  Lead for Panopticon Streaming Analytics will present a paper on:

Using Kafka Streams to Analyze Live Trading Activity for Crypto Exchanges

Cryptocurrency exchanges like Coinbase, Binance, and Kraken enable investors to buy, sell and trade cryptocurrencies, including Bitcoin, Litecoin, Ethereum and many more. Depending on the exchange, trades can be made using fiat currencies (legal government tender like U.S. dollars or Euros) or other cryptocurrencies. Most exchanges also allow investors to purchase one type of cryptocurrency with another (for example, buy Bitcoin with Ethereum.) Given the high velocity and high volatility of cryptocurrency valuations, monitoring and analyzing trading activity and the performance of trading algorithms is daunting. Kafka Streams provides a perfect infrastructure to support visibility into the market and participant behavior with a very high degree of temporal accuracy, which is critical when trading such volatile instruments.

In particular, cryptocurrency traders need several ways to visualize trading activity and rebuild and view their order books at full depth. They need tools that can make large numbers of complex real-time calculations, including:

  • Best bids and offers
  • Cumulative sizes for bids and offers
  • Spread to the median
  • Deltas between price events
  • Time-weighted averages
  • Message rates (new, cancel, trade, replace)
  • Cumulative trade flow

All calculations must be done for multiple pairs of fiat currencies and cryptocurrencies in real time throughout the trading day. Traders must have visibility into all aspects of every order through to execution. New tools leverage the power of Kafka Streams that enable traders themselves to build directed graphs on screen, without writing any code. A directed graphs control data flows, calculations, and statistical analysis of cryptocurrency trading data and can output it the screen for in depth monitoring and analysis of real time data as well as historical trading data stored in in-memory time series databases. This paper describes practical approaches to building and deploying Kafka Streams to support cryptocurrency trading.
