Apache Flink Flink is an open source framework and distributed engine for stateful stream processing. High Performance Fault Tolerance Stateful Processing Flexible APIs Flink Runtime Stateful Computations over Data Streams 4 @morsapaes Learn more: flink.apache.org
Use Cases This gives you a robust foundation for a wide range of use cases: Streaming Analytics & ML Stateful Stream Processing Event-Driven Applications Streams, State, Time SQL, PyFlink, Tables Stateful Functions Flink Runtime Stateful Computations over Data Streams 5 @morsapaes Learn more: flink.apache.org
Use Cases Classical, core stream processing use cases that build on the primitives of streams, state and time. Streaming Analytics & ML Stateful Stream Processing Event-Driven Applications Streams, State, Time SQL, PyFlink, Tables Stateful Functions Flink Runtime Stateful Computations over Data Streams 6 @morsapaes Learn more: flink.apache.org
Stateful Stream Processing Classical, core stream processing use cases that build on the primitives of streams, state and time. ● Explicit control over these primitives ● Complex computations and customization ● Maximize performance and reliability Example Use Cases Large-scale Data Pipelines 7 @morsapaes ML-Based Fraud Detection Service Monitoring & Anomaly Detection
Use Cases More high-level or domain-specific use cases that can be modeled with SQL or Python and dynamic tables. Streaming Analytics & ML Stateful Stream Processing Event-Driven Applications Streams, State, Time SQL, PyFlink, Tables Stateful Functions Flink Runtime Stateful Computations over Data Streams 8 @morsapaes Learn more: flink.apache.org
Streaming Analytics & ML More high-level or domain-specific use cases that can be modeled with SQL or Python and dynamic tables. ● Focus on logic, not implementation ● Mixed workloads (batch and streaming) ● Maximize developer speed and autonomy Example Use Cases Unified Online/Offline Model Training 9 @morsapaes E2E Streaming Analytics Pipelines ML Feature Generation

Python is…pretty stacked? Mature analytics stack, with libraries that are fast and intuitive. 12 @morsapaes Source: JetBrains’ Developer Ecosystem Report 2020
…and also timeless! 1995 2008 2003 2015 Mature analytics stack, with libraries that are fast and intuitive. 2001 13 @morsapaes Source: JetBrains’ Developer Ecosystem Report 2020
…and also timeless! 1995 2008 2003 2015 Mature analytics stack, with libraries that are fast and intuitive. 2001 Older libraries are mostly restricted to a data size that fits in memory (RAM), and designed to run on a single core (CPU). 14 @morsapaes
This is a problem. 15 @morsapaes
16 @morsapaes
But you still want to use these powerful libraries, right? 17 @morsapaes
Why PyFlink? 18 @morsapaes
Why PyFlink? Expose the functionality of Flink to Python users 19 @morsapaes
Why PyFlink? Distribute and scale the functionality of Python through Flink 20 @morsapaes Learn more: The Integration of Pandas into PyFlink.
