Retrieving Test Data

We can now call the RESTful service to provide test data that is generated from the profile that is maintained by the Data Sample Analyzer microservice.

./scripts/curl-tdg.sh names

ArchConfWorkshopUser:~/environment $ ./scripts/curl-tdg.sh names
Jonn
ArchConfWorkshopUser:~/environment $ ./scripts/curl-tdg.sh names
Jon
ArchConfWorkshopUser:~/environment $ ./scripts/curl-tdg.sh names

{% hint style="info" %} Notice that the test data generated is very limited due to the data we entered:

>John
>Jonny
>Johny
>Jonathon
>Johnathon
>Jon

The first 2 letters is always Jo and the 3rd character is either a n or a h {% endhint %}

Continuous Analyzing

First, ensure that the Data Analyzer microservice for the names topic is still running.

./target/debug/tdg_analyzer --topic names

Using the terminal where the Kafka producer is still running for the names topic, start feeding it more names.

kafka_2.13-2.6.0/bin/kafka-console-producer.sh --topic names --bootstrap-server localhost:9092

>Chris
>Christopher
>Kris
>Kristy                   
>Christian  
>Christy

{% hint style="info" %} You should see messages in the Data Analyzer's consoler that the names are being processed. {% endhint %}

Call the RESTful endpoint again and see what test data is now generated.
