![]() ![]() All we need to do is install it:īut like in any respectable pizzeria, we allow people to add toppings from a list, and similarly to the above, we can define a custom pizza_toppings function. We'll use the kafka-python client to build our producer. This step is, strictly speaking, not fundamental, but will allow us to check our producer by reviewing the pushed records in Aiven.io console Topics tab. The last step needed in the configuration is to enable the Kafka REST API (Karapace) in Kafka's console Overview tab, for our cluster. In order to allow topics to be created on the fly while pushing the first record, in this tutorial we'll enable the to_create_topics_enable parameter in Aiven.io console Overview tab scroll down to the Advanced configuration section and then click the + Add configuration option menu. 1.2 Auto topic creation and enabling Kafka REST APIsīy default, Kafka producers can push data only to pre-created topics. On the Overview tab, I can also take note of the Service URI (usually in the form -.e:) that we'll use to correctly point our producer to the Kafka cluster. Then download them to our computer creates 3 files: We can go to the Overview tab of our Kafka instance in Aiven.io console where we can easily find the Access Key, Access Certificate and CA Certificate. While we're waiting for the service to be up and running, we can already start preparing for the next step: downloading the certificates required to connect. ![]() It will take a few minutes before our Kafka 3-node cluster shows up in the RUNNING state. For our initial test we're ok in using a Startup plan, knowing we can always upgrade (or downgrade) in the future. Your choice depends on where you're located or where you plan to provide your services. ![]() Since I'm based in Italy I could easily go for the recently created aws-eu-south AWS region, located in Milan, to minimize latency. Select the service plan based on our needs.Select the Cloud provider we want to deploy our services to, together with the Cloud region.Select the Kafka service (if we're picky we can also choose our favorite Apache Kafka version).Navigate to Aiven.io console and sign in (or sign up it's quick and easy). ![]() For this example we'll need a Kafka cluster. In this blog post I'll walk you through how to create such a fake dataset for Kafka with a hot topic in mind: Pizza! 1. Even if you know your data schema, creating a coherent set of rows from scratch is challenging. Finding streaming data sources is a hard task, and, especially if you just want to test the basics of the platform, setting them up properly can be quite cumbersome.Ĭreating fake data by hand is also not trivial. Not only is it empty by default, but it is also a streaming data platform that works by ingesting, transforming and distributing data on the fly - and it expects a continuous flow of data. With Apache Kafka, the scale of this problem is even larger. Those datasets, however, are pretty static and do not always provide the set of features, fields or cardinality you need to perform your trials. Several platforms solve this problem by offering pre-filled sample datasets that can be installed or enabled with the help of few commands. This makes them hard to use for testing, which is still needed to evaluate whether a solution fits your use case. The tool can be used to generate test data from scratch or from existing data.If you're just interested in a ready-to-go pizza-based Kafka Producer, check out the related Github repo! Data platforms are empty shellsĭatabases, data lakes, and datastores in general are cool pieces of technology allowing anyone to manage and analyze data, but they share a common problem: they are completely empty by default. Only a few simple entries are necessary to generate comprehensive (realistic) test data. It reads your database and displays tables and columns with their data generation settings. The tool can be used by DBAs, developers, or testers, who need sample data to test a database-driven application.ĭatanamic Data Generator makes database test data generation easy and painless. Writing your own test data generators or scripts is time consuming.
