I have a simple avro schema that looks like this:
{
"type": "record",
"name": "transaction",
"namespace": "com.mycompany",
"doc": "Transaction records",
"fields": [
{
"name": "version",
"type": "int",
"default": 1,
"doc": "version the class"
},
{
"name": "eventType",
"type": "string",
"default": "saleTransaction",
"doc": "event type"
},
{
"name": "writeTimestamp",
"type": "org.joda.time.DateTime",
"doc": "Timestamp when this event was written to the stream"
},
{
"name": "originatingClient",
"type": "string",
"doc": "identifier of the originating client"
}
}
When I compile it using avro-maven-plugin, I get the following error:
ERROR] Failed to execute goal
Execution transaction-schemas of goal org.apache.avro:avro-maven-plugin:1.8.0:schema failed: "org.joda.time.DateTime" is not a defined name. The type of the "writeTimestamp" field must be a defined name or a {"type": ...} expression. -> [Help 1]
How do I get this to work?
There is no date support as of now in Avro, you would have to store the time as a long. And there is no support for custom types, as that would mean to support avro serialization and deserialization of that type.
