Avro C : How update a record or add fields one at a time

[Murali K. Kandula]

Hello All,



"{\"type\":\"record\",\
  \"name\":\"Person\",\
  \"fields\":[\
     {\"name\": \"ID\", \"type\": \"long\"},\
     {\"name\": \"First\", \"type\": \"string\"},\
     {\"name\": \"Last\", \"type\": \"string\"},\
     {\"name\": \"Phone\", \"type\": \"string\"},\
     {\"name\": \"Age\", \"type\": \"int\"}]}”;


For the schema mentioned above is it possible to add fields one at a time for a 
particular record. Ex: Let say a record with values ( ID: 1, first: abcd, 
last:xyz, phone: 111-222-3344, age:30) can we write this record to the file 
with only the field ID(with value 1) and then later update the record with ID( 
of value 1) with first,last,phone and age.


Please let me know if it’s possible.


Thanks
