Defining the schema
The first step is to define the Avro schema. As a reminder, our HealthCheck class looks like Listing 5.1:
public final class HealthCheck { private String event; private String factory; private String serialNumber; private String type; private String status; private Date lastStartedAt; private float temperature; private String ipAddress;}

Now, with the representation of this message in Avro format, the schema (that is, the template) of all the messages of this type in Avro would be Listing 5.2:
{ "name": "HealthCheck", "namespace": "kioto.avro", "type": "record", "fields": [ { "name": "event", "type": "string" }, { "name": "factory", "type": "string" }, { "name": "serialNumber", "type": "string" ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
