You can find more detailed information on the supported tools and integrations in Materialize’s Metabase or any other Postgres wire-compatible tool. Typically, a dashboard is used to visualize data and you can use a business intelligence tool like Redpanda's integration with Materialize allows real-time insights into your data streams. Run the following command:Īgain, running the same query after some time, we can see a change in the values. You can also check the output of the individual producers using Redpanda’s CLI tool, rpk.

Once the script runs successfully, you should see messages produced on the topics.

Entries pushed by the producer are of the type JSON.

The insertion goes on until there are 100000 entries to fitbit_owner

Insert one entry to fitbit_owner and one to five entries to fitbit_activity_tracker every 0.5 seconds.

Create the topics fitbit_activity_tracker and fitbit_owner.

Running the producer code will accomplish the following : The producer logic for our application can be found in the redpanda_producer.py file. Here is a simple schema diagram of the topics: The values of owner_id and date between the two topics are the same, forming a pseudo foreign key relationship between the pair. The second topic, called fitbit_owner, has the owner's name along with the owner_id and date.

Apart from this, it also includes a couple of id fields called owner_id and activity_id. It records the steps, date, calories burnt, active minutes, and sedentary minutes. The first one is called fitbit_activity_tracker, which shows the various activities generated on a given day in 2022. In Redpanda, data is read from multiple sources and then organized into topics. The schema we are using is that of a Fitbit activity tracker. The Kafka library supports only Python version >=3.7. For this, we require a Kafka library to push the data onto our topics. To generate data and simulate our data streams, we will use Python. Materializeĭownload and set up Materialize.

Since Materialize uses psql as its CLI, you need to install PostgreSQL. Note: If you are running in a Mac/Docker environment, please note down the IP addresses of the brokers, which you can find after the installation. To see other installation options, view the documentation here. In this document, we will be running in a Linux (Ubuntu20) environment. Please follow the README instructions to get the code up and running in your environment. You can find the code to build the demo Fitbit activity tracker app in Let us now look at the prerequisites to get started. (This scenario is for demonstration purposes only and may not necessarily reflect a typical use case.) In this tutorial, we’re using a sample Fitbit tracker app to stream source data with Redpanda and feed it into in-memory views using Materialize. By using Redpanda and Materialize together in our app stack, we can get real-time views of the data to share with users. Since users can work out at any time, data coming in through any user’s Fitbit tracker has to be processed immediately so that the leaderboard is updated in real-time. Imagine that an organization wants to run a daily challenge based on the number of calories burnt by users and give out daily rewards to the top three fitness enthusiasts on the leaderboard. Use case: Integrating Redpanda and Materialize for IoT data streaming While we will be discussing Materialize, Redpanda, and Fitbit data in this blog’s use case, it’s also worth noting that similar IoT streaming applications can be created using these tools with Apache Pinot®, FastAPI, and Raspberry Pi.

This includes use cases like real-time dashboards, anomaly detection, and event-driven microservices. Materialize is a streaming database that can ingest real-time data streams from Redpanda and make them queryable within seconds, allowing developers to run online analytical processing (OLAP) queries on them.īy combining Redpanda and Materialize, developers can build real-time applications that ingest and process IoT data at scale. It enables ingesting large volumes of IoT data at high throughputs, and provides scalable and fault-tolerant storage. It is purpose-built to deliver speed, accuracy, and safety for streaming data.

Redpanda is a data streaming platform API-compatible with the Apache Kafka ® ecosystem. When considering tools for processing IoT data in real-time, a good combination to use together is Redpanda and Materialize. Collecting and processing IoT data has been challenging due to the classic “3Vs” of big data: volume, velocity, and veracity, imposing IoT analytics systems to acquire sophisticated data storage and processing infrastructure. The data generated by Internet of Things (IoT) devices are considered big data.
