I've an avro file and needs to be converted into CSV
Schema of the avro file is
{
"type" : "record",
"name" : "Activity",
"namespace" : "xyz.domain",
"fields" : [ {
"name" : "activityDate",
"type" : [ "null", "string" ],
"default" : null
}, {
"name" : "activityTypeId",
"type" : [ "null", "int" ],
"default" : null
}, {
"name" : "campionId",
"type" : [ "null", "int" ],
"default" : null
}, {
"name" : "id",
"type" : [ "null", "int" ],
"default" : null
}, {
"name" : "SecondId",
"type" : [ "null", "int" ],
"default" : null
}, {
"name" : "GUID",
"type" : [ "null", "string" ],
"default" : null
}, {
"name" : "primaryAttributeValue",
"type" : [ "null", "string" ],
"default" : null
}, {
"name" : "primaryAttributeValueId",
"type" : [ "null", "int" ],
"default" : null
}, {
"name" : "attributes",
"type" : [ "null", {
"type" : "array",
"items" : {
"type" : "record",
"name" : "Attribute",
"fields" : [ {
"name" : "apiName",
"type" : [ "null", "string" ],
"default" : null
}, {
"name" : "name",
"type" : [ "null", "string" ],
"default" : null
}, {
"name" : "value",
"type" : [ "null", "string" ],
"default" : null
} ]
},
"java-class" : "java.util.List"
} ],
"default" : null
} ]
}
I'm able to read the file but don;t know how to retrieve value from the
nested array ( api name, name and value from the attribute array).
here is my code
fr, err := goavro.NewReader(goavro.FromReader(r))
for fr.Scan() {
datum, err := fr.Read()
if err != nil {
log.Println("cannot read datum: ", err)
continue
}
fmt.Println("RECORD: ", datum)
record := datum.(*goavro.Record)
//_, err = reader.Read(varactivity,
datum.(*goavro.Record))
fmt.Println("===================================================")
//fmt.Println(record)
//fmt.Println("Record Name:", record.Name)
//fmt.Println("Record Fields:")
for i, field := range record.Fields {
fmt.Println(" field", i, field.Name, ":",
field.Datum)
}
}
Can you please provide a sample code to convert the structure into CSV.
Thanks
