Step 1: Creating A Stream

Creating A Stream

In this step you will create and configure a stream with the correct configuration. You will need this stream for your producer application to produce data and your consumer to fetch it.

Log in to the Self-Service portal using the credentials supplied by Axual. The following screen will be shown:

  3. Select "default" as your team

  4. Select "AVRO" for both "Key type" and "Value type"

  5. Select io.axual.client.example.schema.Application as the "Key schema"

  6. Select io.axual.client.example.schema.ApplicationLogEvent as the "Value schema"

You will see that the stream is created.

Axual allows to configure streams based on the environment they are used in. E.g. in "Development" you might want to have a shorter retention time than in "Production". In the next step you will configure the stream in at least one environment.

Configuring Your New Stream

When configuring the stream, you must configure it for an environment. The "example" environment comes preconfigured and can be used.

  1. Click "Configure stream"

Config stream view
  1. Enter a retention time (e.g. 1 day)

  2. Choose 1.0.0 as the Key and Value Schema version in the dropdown

  3. Enter a number of partitions (e.g. 2)

  4. Click "Save" to configure your stream. The stream has now become active in the "example" environment.

Next step: Enabling Security

In step 3 you will enable security to make sure you can connect to the platform securely and your application(s) can be authorized to access the stream.
