Can I split an Apache Avro schema across multiple files?

Question

I can do,

{
    \"type\": \"record\",
    \"name\": \"Foo\",
    \"fields\": [
        {\"name\": \"bar\", \"type\": {
            \"type\": \"record\",
             


        

Answer 1

Yes, it's possible.

I've done that in my java project by defining common schema files in avro-maven-plugin Example:

search_result.avro:

{"namespace": "com.myorg.other",
 "type": "record",
 "name": "SearchResult",
 "fields": [
     {"name": "type", "type": "SearchResultType"},
     {"name": "keyWord",  "type": "string"},
     {"name": "searchEngine", "type": "string"},
     {"name": "position", "type": "int"},
     {"name": "userAction", "type": "UserAction"}
 ]
}

search_suggest.avro:

{"namespace": "com.myorg.other",
 "type": "record",
 "name": "SearchSuggest",
 "fields": [
     {"name": "suggest", "type": "string"},
     {"name": "request",  "type": "string"},
     {"name": "searchEngine", "type": "string"},
     {"name": "position", "type": "int"},
     {"name": "userAction", "type": "UserAction"},
     {"name": "timestamp", "type": "long"}
 ]
}

user_action.avro:

{"namespace": "com.myorg.other",
 "type": "enum",
 "name": "UserAction",
 "symbols": ["S", "V", "C"]
}

search_result_type.avro

{"namespace": "com.myorg.other",
 "type": "enum",
 "name": "SearchResultType",
 "symbols": ["O", "S", "A"]
}

avro-maven-plugin configuration:

    org.apache.avro
avro-maven-plugin
1.7.4
    
    
        generate-sources
        
        schema
        
    
     ${project.basedir}/src/main/resources/avro
         ${project.basedir}/src/main/java/
     
         **/*.avro
     
     
              ${project.basedir}/src/main/resources/avro/user_action.avro
              ${project.basedir}/src/main/resources/avro/search_result_type.avro
