Democratizing ML Pipelines using StreamPipes: Flexible Model Integration and Serving for Industrial IoT Applications
Philipp Zehnder, Marco Heyden

Apache StreamPipes (incubating) is an industrial IoT toolbox which enables non-technical users to flexibly connect, analyze and exploit continuous data streams. Under the hood, StreamPipes integrates an event-driven microservice architecture with a rich graphical user interface that lets users create stream processing pipelines. In this talk, we focus on analyzing image data from industrial cameras with Machine Learning (ML) and Apache StreamPipes. Based on an application example for Visual Quality Inspection, techniques for integrating ML models into StreamPipes are presented and a demo shows how product defects can be easily recognized in real time using a no-code approach.
The talk gives an overview of Apache StreamPipes, highlights the positioning of StreamPipes within the ASF IoT ecosystem and demonstrates how machine learning models can be easily integrated and evaluated within a StreamPipes application.

StreamPipes’ New Kids on the Block: An Introduction to Edge Extensions, Client API and Data Explorer
Dominik Riemer, Patrick Wiener

Several community initiatives are working on major feature extensions to Apache StreamPipes which aim to ease the time-consuming task of analyzing Industrial IoT data in a self-service manner. In this talk, we focus on a feature tour of the three latest Apache StreamPipes features that are to be introduced in 2021: First, we introduce StreamPipes Edge Extensions, which allow users to flexibly select deployment targets of pipeline elements, enabling geographic distribution of pipeline elements over the edge-to-cloud continuum. Second, integration of StreamPipes with external applications is significantly improved with the Apache StreamPipes API & Client libraries, a new developer-oriented way to interact with StreamPipes concepts programmatically. Finally, we demonstrate the recently introduced data explorer which eases the interaction and visual exploration of persisted data streams in StreamPipes. The talk will be accompanied by several live demos that illustrate the practical outcome for Apache StreamPipes users.

Cracking the Nut, Solving Edge AI with Apache Tools and Frameworks
Timothy Spann

Today, data is being generated from devices and containers living at the edge of networks, clouds and data centers. We need to run business logic, analytics and deep learning at the edge before we start our real-time streaming flows. Fortunately using the all Apache FLiP stack we can do this with ease! Streaming AI Powered Analytics From the Edge to the Data Center is now a simple use case. With MiNiFi we can ingest the data, do data checks, cleansing, run machine learning and deep learning models and route our data in real-time to Apache NiFi and Apache Pulsar for further transformations and processing. Apache Flink will provide our advanced streaming capabilities fed real-time via Apache Pulsar topics. Apache MXNet models will run both at the edge and in our data centers via Apache NiFi and MiNiFi. Our final data will be stored in Apache Kudu via Apache NiFi for final SQL analytics. We add microservices in Pulsar Functions. Tools:
Apache Flink, Apache Pulsar, Apache NiFi, MiNiFi, Apache MXNet, Apache Kudu, Apache Impala, Apache HDFS

Building and Scaling Robust Zero-code IoT Streaming Data Pipelines with Open Source Technologies
Paul Brebner

With the rapid onset of the global Covid-19 Pandemic in 2020 the USA Centers for Disease Control and Prevention (CDC) quickly implemented a new Covid-19 pipeline to collect testing data from all of the USA’s states and territories, and produce multiple consumable results for federal and public agencies. They did this in under 30 days, using Apache Kafka.
Inspired by this story, we built two demonstration streaming pipelines for ingesting, storing, and visualizing public IoT data (Tidal data from NOAA, the National Oceanic and Atmospheric Administration) using multiple open source technologies. The common ingestion technologies were Apache Kafka, Apache Kafka Connect, and Apache Camel Kafka Connector, supplemented with Prometheus and Grafana for monitoring. The initial experiment used Open Distro for Elasticsearch and Kibana as the target storage and visualisation technologies, while the second experiment used PostgreSQL and Apache Superset.
In this talk we introduce each technology and the pipeline architecture, and walk through the steps followed, challenges encountered, and solutions used to build reliable and scalable pipelines, and visualize the results (including Tidal periods, ranges and locations). We compare and contrast the two approaches, focussing on exception handling, scalability, performance and monitoring, and the pros and cons of the two visualization technologies (Kibana and Superset).

Since learning to program on a VAX 11/780, Paul has extensive R&D and consulting experience in distributed systems, technology innovation, software architecture and engineering, software performance and scalability, grid and cloud computing, and data analytics and machine learning.

PMEM-backed Repositories for more high-performance Apache NiFi
Takashi Menjo

Low latency and high throughput are desirable characteristics for dataflow systems such as Apache NiFi to process large-scale IoT data fast. NiFi keeps track of all dataflow in the system by storing their content, attribute, and provenance in disks, which needs I/O and tends to be a performance bottleneck. Persistent memory (PMEM), a non-volatile and byte-addressable memory installed into DIMM slots, is a new alternative to disk and could bring more performance. However, to benefit much from PMEM, programs need to change to be PMEM-aware. In this talk, I’ll show my proposal to NiFi, which introduces PMEM-backed Content, FlowFile, and Provenance Repositories, based on PMEM-related technologies such as Filesystem DAX (Direct Access) and PMDK (Persistent Memory Development Kit). Note that it is for now a proposal to NiFi but could be applied to other data management systems such as Kafka. This talk covers how my proposal improves NiFi’s latency and throughput, how it modifies NiFi to use DAX and PMDK, the results of performance tests when using Optane PMem in App Direct Mode, and one more proposal for NiFi to be more PMEM-aware.

Takashi Menjo is a Researcher at NTT Software Innovation Center located in Tokyo, Japan. He works in the area of PMEM-aware applications, especially redesigning traditional disk-based software such as PostgreSQL or Apache NiFi.

A machine learning hub for IoT data using Apache Madlib
Nitin Borwankar

Apache Madlib adds comprehensive statistics and machine learning capabilities to Postgres. A Cambrian explosion of IoT data sources has meant massive data integration overhead long before you can get to ML. But what if the ML step itself was very low friction and done all inside the database. And what if it was possible to access raw data files from sensors so a lot of ETL was actually LTE - load, then transform then extract. Combining Apache Madlib with the super powers of Postgres extensions allows such... well... "massive synergies".
We look at data from human sleep monitoring devices and heart rate monitors to explore and exercise the capabilities of this powerful combination and see how we can set alarms and thresholds to warn of dangerous situations. Predictive analytics and visualization are also made much simpler which we demonstrate using this health data.

Nitin Borwankar has played almost every role in the software development lifecycle over 25 years from QA Engineer, to App developer, Database Architect, Product Manager, Engineering Manager and Data Scientist. He is a founder and CTO of Numericc.

Unified fieldbus API with Apache PLC4X
Łukasz Dywicki

The universe is full of standards which compete in multiple dimensions. Same truth applies to manufacturing industry. Space between standards is filled by various software libraries which are intended to let both - computers as well as micro controllers interact with end hardware.
During this presentation we will have a look on Open Systems Interconnection (OSI) model and see where typical fieldbus technology. We will briefly see major differences in usage of field buses compared to traditional TCP or UDP based communications.
In second part of this talk we will take a look on typical manufacturing solutions such as Profinet, CANopen and Ethernet/IP. We will learn basis of one of these standards and see how to acquire data through Apache PLC4X client API. Finally we will compare how to interact with remaining two standards using APIs introduced earlier.

Polyglot Apache PLC4X
Christofer Dutz

Apache PLC4X had the "X" in it's name from the start as it was always intended to provide APIs for accessing PLCs and industrial hardware in multiple languages.
But creating drivers for "N" protocols in "M" languages is a maintenance nightmare.
In this session I will not only take you through the available APIs in Java, Go, C and possibly C#/.Net and Python, but also explain how we manage to do this via code-generation.
In the past 2 years we have created a framework and the necessary tooling for generating more than 90% of a drivers code from a machine- and human-readable format.
In the second part I'll take you on a journey through this toolset.

Full blooded Apache and Open-Source enthusiast. Invests all of his work and private time in multiple Apache Projects. Deeply interested in the IoT Area he is currently VP of the Apache PLC4X project and deeply involved in multiple Apache projects as well as mentor to multiple podlings in the Apache Incubator.
