-----------------------------------
Summary: C++ API compileJsonSchema ignores "doc" and custom
attributes on a field/record
Key: AVRO-1256
URL: https://issues.apache.org/jira/browse/AVRO-1256
Project: Avro
Issue Type: Improvement
Components: c++
Affects Versions: 1.7.2
Environment: Running on all platforms (Windows, OSX, Linux)
Reporter: Tim Menninger
Priority: Minor
It appears that when my JSON is compiled into a valid schema object it is
ignoring all types of "documentation" that I am trying to adorn with each field
in my record. Reading through the Java issues it seems that this was a bug and
fixed (AVRO-601, AVRO-612, AVRO-779) but it seems the C++ implementation has
yet to adopt this feature? This is my sample schema, I have attempted to insert
both "doc" and "mycustom" in multiple places to see if it is supported at any
level. Please excuse if there appears to be a syntax error in the JSON I hand
tweaked some of this. The schema is valid and successfully parses.
{
"type": "record",
"name": "myschema",
"doc": "Doc Meta",
"mycustom": "My Custom",
"fields": [
{ "name":"field_a","type":["string","null"], "doc":"Doc Meta",
"mycustom":"My Custom A"},
{ "name":"field_b","type":["string","null"], "doc":"Doc Meta",
"mycustom":"My Custom B"},
{ "name":"field_c","type":["string","null"], "doc":"Doc Meta",
"mycustom":"My Custom C"}
]
}
I looked through the SchemaTests.cc code for 1.7.3 and there was not a test
case for this there so i didn't think this was addressed in that version. I am
running 1.7.2. When this schema is used to load with compileJsonSchema and then
a file is serialized the file schema looks like this.
{
"type":"record",
"name":"myschema",
"fields": [
{ "name":"field_a","type":["string","null"]},
{ "name":"field_b","type":["string","null"]},
{ "name":"field_c","type":["string","null"]}
]
}
