A tour of Redpanda Streamfest 2024
Data lakes are a great way to store almost any type of data. Yet, if you want to combine them with incoming streams of data, the complexity of writing extract and load pipelines to get all your messages in one place for analytical querying can be burdensome.
In such a case, you can use a streaming data platform like Redpanda as the event storage of your application, and a data lake like S3 or Google Cloud Storage to house various other data that you collect from different sources. Combining this data to unlock its analytical treasures is easier than it sounds.
In this tutorial, we walk through an example setup where we use Trino to run federated queries against a slowly changing data set that lives in an S3-like object storage (MinIO), combined with streaming data from a Redpanda topic.
In the architecture diagram above, we get a glimpse of how the various components of this architecture interact with each other. MinIO serves as the storage layer over our files in the “data lake” while Redpanda is responsible for the live, streaming data side. Both sources are queried through Trino, the SQL-based execution engine. Trino requires a few backend components to function, like the Hive metastore and a relational database, for which we will use a plain MariaDB instance.
You can access the demo code for this tutorial at any time in this GitHub repo.
The building blocks
1. The data lake
The data lake portion of our setup consists of two main components: the storage layer and the query engine layer, which is responsible for executing the queries.
This is how they look in detail:
1.1 The storage layer: MinIO
MinIO delivers scalable, secure, S3-compatible object storage. It can be self-hosted, which means we can build our downstream components on top of it in the same manner as if we were using S3. This compatibility helps with prototyping and makes development cycles faster than having to spin up an AWS infrastructure.
As with the other services we’ll cover in this demo, we deploy MinIO via Docker Compose:
minio:
hostname: minio
image: 'minio/minio:latest'
container_name: minio
ports:
- "9001:9001"
- "9000:9000"
command: [ "server", "/data", "--console-address", ":9001" ]
volumes:
- minio-data:/data
environment:
MINIO_ROOT_USER: minio
MINIO_ROOT_PASSWORD: minio123
MINIO_ACCESS_KEY: minio
MINIO_SECRET_KEY: minio123
networks:
- trinoTo create our "data lake" (e.g. load a file from our file system into the object storage) we can use the official command line client for MinIO, called mc. With mc, we can automate the steps of initializing our static data with a Docker container like this:
mc:
depends_on:
- minio
image: minio/mc
container_name: mc
entrypoint: >
/bin/sh -c "
until (/usr/bin/mc config host add minio http://minio:9000 minio minio123) do echo '...waiting...' && sleep 1; done;
/usr/bin/mc rm -r --force minio/users;
/usr/bin/mc mb minio/users;
/usr/bin/mc policy set public minio/users;
/usr/bin/mc cp /data/mock_user_data.parq minio/users/mock_user_data.parq;
exit 0;
"
networks:
- trino
volumes:
- ./data/mock_user_data.parq:/data/mock_user_data.parqThis container will create a bucket called minio/users and upload the Apache Parquet® file mock_user_data.parq to it. (If you’re wondering where this parquet file came from, don’t worry - we'll discuss that in the next section.)
So far, if we run the following Docker Compose command…
docker-compose up minio mc
…we'll have our data lake ready to go in a second. To verify this step the output should look like this:
minio |
minio | Status: 1 Online, 0 Offline.
minio | API: http://172.24.0.2:9000 http://127.0.0.1:9000

mc | `/data/mock_user_data.parq` -> `minio/users/mock_user_data.parq`
mc | Total: 0 B, Transferred: 58.38 KiB, Speed: 1.59 MiB/s1.2 The query engine: Trino
Trino is an SQL-compliant query engine that is compatible with numerous data sources as well as various business intelligence tools, such as Tableau and Power BI. Trino has built-in connectors for most commonly-used data storage options, like Hive, PostgreSQL, BigQuery, and Apache Kafka®.
Trino has three main components:
- Coordinator
- Worker
- Hive metastore
The Coordinator and Worker will live in the same service for demonstration purposes but in a production environment, to achieve scalability and high availability, they should be run separately. This can be achieved via Docker:
trino-coordinator:
container_name: trino-coordinator
image: 'trinodb/trino:latest'
hostname: trino-coordinator
ports:
- '8080:8080'
volumes:
- ./etc:/etc/trino
networks:
- trino1.2a Hive metastore
Our tables will be defined through the Hive metastore (HMS). HMS is the catalog of all the collections held in our object storage. When new data is inserted into our tables, HMS takes care of registering the schema and other metadata in a durable database for us. The HMS is a simple service with a binary API using the Thrift protocol. The metadata that HMS updates lives in a MariaDB instance.
The relevant Docker Compose snippet looks like this:
hive-metastore:
container_name: hive-metastore
hostname: hive-metastore
image: 'bitsondatadev/hive-metastore:latest'
ports:
- '9083:9083'
volumes:
- ./conf/metastore-site.xml:/opt/apache-hive-metastore-3.0.0-bin/conf/metastore-site.xml:ro
environment:
METASTORE_DB_HOSTNAME: mariadb
depends_on:
- mariadb
networks:
- trino
mariadb:
container_name: mariadb
image: 'mariadb:latest'
hostname: mariadb
ports:
- '3306:3306'
environment:
MYSQL_ROOT_PASSWORD: admin
MYSQL_USER: admin
MYSQL_PASSWORD: admin
MYSQL_DATABASE: metastore_db
volumes:
- ./metastore-data:/var/lib/mysql
networks:
- trinoThe metastore-site.xml file is used to configure the metastore so it can access the database and MinIO. The HMS is configured via the file /etc/catalog/hive.properties. This tells Trino how to access the metastore and the object storage.
connector.name=hive-hadoop2
hive.metastore.uri=thrift://hive-metastore:9083
hive.s3.path-style-access=true
hive.s3.endpoint=http://minio:9000
hive.s3.aws-access-key=minio
hive.s3.aws-secret-key=minio123The Redpanda connection configuration lives in /etc/catalog/kafka.properties.
The contents of this configuation file are fairly minimal: It simply specifies how Trino will be able to find our Redpanda broker and which topic it should ingest from. The kafka.table-names is the property that specifies the topic name.
connector.name=kafka
kafka.nodes=redpanda:9092
kafka.table-names=user_events
kafka.hide-internal-columns=falseLet's spin up every service required for our example and continue with the streaming setup!
docker-compose up trino-coordinator mariadb hive-metastore minio mc
2. The streaming platform: Redpanda
For the streaming part of our project, we will use Redpanda, a Kafka API-compatible event streaming engine that is faster, simpler, and more reliable. This API compatibility will help us set up the connection between our live data and our data lake, as our query-engine, Trino, has a working Kafka connector already built.
For more information about the Trino connector, head over to the official documentation here.
3. The data
For this tutorial, we will use mock event data that resembles users interacting with a website. To generate our "slowly-changing" data set that will live in MinIO, we can use mockaroo. The generated data that we export to a csv file will look like this:
user_id,first_name,last_name,email,gender,ip_address
1,Kim,Saltman,ksaltman0@mlb.com,Female,177.38.222.225
2,Waldo,Ducker,wducker1@newyorker.com,Male,117.68.143.132
3,Iona,Sabater,isabater2@ft.com,Female,233.154.142.64
4,Kelly,Hawyes,khawyes3@rediff.com,Male,121.243.56.88
5,Dulciana,Foxley,dfoxley4@irs.gov,Female,140.138.88.205
6,Monti,Dryden,mdryden5@dailymotion.com,Genderfluid,59.230.189.110
7,Hersch,Nind,hnind6@networksolutions.com,Male,254.181.254.158
8,Renard,Scheffel,rscheffel7@elegantthemes.com,Male,48.115.25.158
9,Asa,Croydon,acroydon8@mit.edu,Male,83.77.36.108
10,Mace,Olekhov,molekhov9@patch.com,Genderfluid,74.185.165.15In order to optimize our data lake, let's convert this file into parquet format with a simple Python script. Parquet is designed as a columnar storage format to support complex data processing. It is a self-describing data format that embeds the schema or structure within the data itself. This will make loading our data a bit easier as we can catch issues with it earlier.
import pandas as pd
def csv_to_parquet(csv_file, parquet_file):
df = pd.read_csv(csv_file)
df.to_parquet(parquet_file)
if __name__ == "__main__":
csv_to_parquet("mock_user_data.csv", "mock_user_data.parq")This concludes the static side of our data set up. The streaming side will be generated by a Python script. In our final queries, we will want to be able to join the two data sets on the user_id field, so our script will include that as well.
The main data generation part involves only a few lines of code:
MOCK_EVENTS = [
"email_click",
"link_1_click",
"link_2_click",
"pdf_download",
"video_play",
"website_visit",
]
# Generate randomized user event data for a non-existing website
data = {
"timestamp": datetime.now().isoformat(), # ISO 8601 timestamp, because Trino can easily parse this
"event_name": random.choice(MOCK_EVENTS),
"event_value": randint(0, 1),
}
# Send the data to the Redpanda topic
key = str(randint(0, 1000)).encode("utf-8")
value = json.dumps(data).encode("utf-8")
producer.send(
EVENTS_TOPIC_NAME,
key=key,
value=value,
)We'll choose one event from our list of mock events and send it to the Redpanda topic.
Redpanda’s Kafka API compatibility lets us set up this data generator as if we were writing an application that interacts with Kafka. To connect to Redpanda, we just have to specify the list of brokers, which will have a different hostname based on the environment we are currently using.
BOOTSTRAP_SERVERS = (
"redpanda:9092"
if os.getenv("RUNTIME_ENVIRONMENT") == "DOCKER"
else "127.0.0.1:54810"
)
producer = KafkaProducer(bootstrap_servers=BOOTSTRAP_SERVERS)With the Admin API, we can also create our destination topic if it doesn't already exist.
# Create kafka topics if running in Docker.
admin_client = KafkaAdminClient(
bootstrap_servers=BOOTSTRAP_SERVERS, client_id="user-event-producer"
)
# Check if topic already exists first
existing_topics = admin_client.list_topics()
if EVENTS_TOPIC_NAME not in existing_topics:
admin_client.create_topics(
[NewTopic(EVENTS_TOPIC_NAME, num_partitions=1, replication_factor=1)]
)The data we push to Redpanda will look like this:
Key:
123Value:
The key is the user_id, which is a randomly generated integer in this case, but we should be able to match it to our static data set, as that contains integers from 1 to 1000 as well. The value has the timestamp of the event in ISO 8601 format, the event name, and the event value.
To run the data generator we can use the following command:
docker-compose up redpanda producerThis will spin up our local Redpanda cluster and start the producer. The logs will look as follows:
producer | Sent data to Redpanda topic user_events: b'672' - b'{"timestamp": "2022-08-07T13:56:59.810898", "event_name": "link_1_click", "event_value": 1}', sleeping for 1 second
producer | Sent data to Redpanda topic user_events: b'696' - b'{"timestamp": "2022-08-07T13:56:59.921337", "event_name": "link_2_click", "event_value": 1}', sleeping for 1 second

producer | Sent data to Redpanda topic user_events: b'118' - b'{"timestamp": "2022-08-07T13:57:00.813905", "event_name": "website_visit", "event_value": 0}', sleeping for 1 second
producer | Sent data to Redpanda topic user_events: b'525' - b'{"timestamp": "2022-08-07T13:57:00.924928", "event_name": "pdf_download", "event_value": 1}', sleeping for 1 second
producer | Sent data to Redpanda topic user_events: b'461' - b'{"timestamp": "2022-08-07T13:57:01.035165", "event_name": "link_2_click", "event_value": 0}', sleeping for 1 secondThere is a short sleep included in the producer for easier testing.
Kafka data is unstructured, and it has no metadata to describe the format of the messages. Without further configuration, the Kafka connector can access the data, and map it in raw form. However, there are no actual columns besides the built-in ones:
trino --server http://localhost:8080 --catalog kafka --schema default
trino:kafka> DESCRIBE user_events
Column | Type | Extra | Comment
-------------------+------------+-------+---------------------------------------------
_partition_id | bigint | | Partition Id
_partition_offset | bigint | | Offset for the message within the partition
_key | varchar | | Key text
_key_corrupt | boolean | | Key data is corrupt
_key_length | bigint | | Total number of key bytes
_message | varchar | | Message text
_message_corrupt | boolean | | Message data is corrupt
_message_length | bigint | | Total number of message bytes
_timestamp | timestamp | | Message timestampThe data from Redpanda can already be queried using Trino, but it is not yet in actual table shape. The raw data is available through the _message and _key columns, but it is not decoded into columns. As the sample data is in JSON format, the JSON functions and operators built into Trino can be used to slice the data.
The Trino Kafka connector supports topic description files to turn raw data into table format. These files are located in the etc/kafka folder in the Trino installation and must end with .json. It is recommended that the file name matches the table name, but this is not necessary.
We have created a schema description file for our topic. It looks like this:
{
"tableName": "user_events",
"schemaName": "default",
"topicName": "user_events",
"dataFormat": "json",
"key": {
"dataFormat": "raw",
"fields": [
{
"name": "user_id",
"type": "VARCHAR",
"hidden": "false"
}
]
},
"message": {
"dataFormat": "json",
"fields": [
{
"name": "timestamp",
"mapping": "timestamp",
"type": "VARCHAR"
},
{
"name": "event_name",
"mapping": "event_name",
"type": "VARCHAR"
},
{
"name": "event_value",
"mapping": "event_value",
"type": "VARCHAR"
}
]
}
}This file is saved as default.user_events.json in the etc/kafka folder and gets copied into our Docker image.
Having the schema description file, we can now query the data:
select user_id, event_name, event_value, timestamp
from user_eventsThis gives us the following output:
user_id | event_name | event_value | timestamp

920 | link_2_click | 0 | 2022-08-07T14:13:38.708060 We now have enough infrastructure to combine the streaming data with our static file!
Query federation!
Now that we have both the static and streaming data, we can start building our queries on top of them.
To start the complete data lake portion of our project, run:
docker-compose up trino-coordinator mariadb hive-metastore minio mc
This will spin up every dependency required for Trino, including the HMS, the MariaDB backend, and it will also start the MinIO server and copy the Parquet file to a bucket.
To start the streaming side of the project, run:
docker-compose up redpanda producer
With everything now running, all we need to do is grab the Trino client so we can connect to the server and run some queries! The required installation steps are detailed here.
To connect to our Trino server, use the following command:
trino --server http://localhost:8080
Before we are able to query our data from the Parquet file, we need to create a schema and a table in the HMS. This can be done with a few SQL statements:
USE hive;
CREATE SCHEMA IF NOT EXISTS users
WITH (location = 's3a://users/');
CREATE TABLE IF NOT EXISTS hive.users.user_data
(
user_id INT,
first_name VARCHAR,
last_name VARCHAR,
email VARCHAR,
gender VARCHAR,
ip_address VARCHAR
)
WITH ( external_location = 's3a://users/',
format = 'PARQUET');These commands will create a schema called users and a table called user_data for us in the HMS with an external location pointing to our Parquet file.
Now we are able to query our parquet file thanks to HMS. To verify, run this command:
select *
from hive.users.user_data;This will give us:
user_id | first_name | last_name | email | gender | ip_address

Conclusion
The opportunities for such an application are endless. Using event timestamps, we can calculate basically any time-based metric we want, while also keeping in-sync with our slowly changing data in our object storage. This functionality has many different uses, including clickstream analytics with customer or user lookups, infrastructure operations analysis, sales analysis, and many other real-time analytics use cases.
The Kafka API-compatibility and ease of deployment of Redpanda allows us to take existing infrastructure elements and replace it with a scalable and persistent event streaming engine like Redpanda. This makes for an easy development environment setup that - with minimal changes - can also be used in production at full scale, meeting your operational and resiliency requirements.
If you have any questions about running this demo, please ask them in the Redpanda Community on Slack. As a reminder, all code for this tutorial is accesible in this GitHub repo, and you can find Redpanda’s main project here.
