Citadel has an effective framework for high-performance real-time event processing using Kdb+ and several of the firm’s platforms have Kdb+ either at the core or close to it. Citadel’s framework builds on the Kdb+ primitives to allow engineers to rapidly develop dynamic event processing systems, from which insights can be drawn in real-time. Despite its advantages, the Q language presents a strong barrier to entry for those unfamiliar with Q. That’s why we’re thrilled by the introduction of PyKx. In this talk, we’ll be taking you through our journey in integrating it into our framework and the challenges it’s helped overcome.
some talking points for the KXCON23 presentation on High Performance, Real-time Event Processing with PyKX | kdb at Citadel:
- Introduction to real-time event processing (CEP)
- Why CEP is important in financial markets
- How kdb and PyKX can be used for CEP
- A reference architecture for CEP with kdb
- Examples of CEP applications with kdb
- Performance benchmarks of kdb CEP
- Future directions for kdb CEP
Here is a more detailed explanation of each point:
- Introduction to real-time event processing (CEP)
CEP is a technology for processing and analyzing streaming data in real time. It is used to detect patterns and events in data as they occur, and to take action based on those events.
Why CEP is important in financial markets
Financial markets are constantly generating new data. This data can be used to identify trading opportunities, manage risk, and make other decisions. However, the data is often streaming in real time, which makes it difficult to process and analyze using traditional methods.
CEP can be used to solve this problem by processing and analyzing streaming data in real time. This allows financial institutions to identify and act on trading opportunities faster, manage risk more effectively, and make better decisions.
How kdb and PyKX can be used for CEP
kdb is a high-performance, in-memory database that is designed for real-time data processing. PyKX is a Python library that provides an interface to kdb.
Together, kdb and PyKX can be used to build high-performance, real-time CEP applications. kdb provides the performance and in-memory capabilities that are essential for CEP, while PyKX provides the flexibility and ease of use of Python.
A reference architecture for CEP with kdb
A typical reference architecture for CEP with kdb would consist of the following components:
* A data source that generates the streaming data
* A kdb server that stores and processes the data
* A PyKX client that connects to the kdb server and performs the CEP operations
* A visualization tool that displays the results of the CEP operations
Examples of CEP applications with kdb
Some examples of CEP applications with kdb include:

* Fraud detection
* Market surveillance
* Risk management
* Trading signal generation
* Order execution
Performance benchmarks of kdb CEP
kdb has been shown to be capable of processing millions of events per second. This makes it a suitable choice for high-performance CEP applications.
Future directions for kdb CEP
kdb is constantly evolving, and new features are being added to the CEP capabilities. Some of the future directions for kdb CEP include:
* Support for more complex event patterns
* Integration with other kdb features, such as machine learning
* Support for distributed processing
I hope this gives you some talking points for your KXCON23 presentation on High Performance, Real-time Event Processing with PyKX | kdb at Citadel. Good luck!
