Avro Flat Schema Format

An Avro schema that uses the flat format contains all of the Avro column-definition fields in one Avro record. The schema is specific to the source object that contains the defined columns.

The following flat schema defines two columns in one record:

{"type" : "record", fields" : [ {
   {"name" : "COL1", "type" : [ "null", "string" ], "doc" : "...", "default" : null}
   {"name" : "COL1_Present", "type" : "boolean", "doc" : …}
   {"name" : "COL1_BeforeImage", "type" : [ "null", "string" ],"doc" : … }
   {"name" : "COL1_BeforeImage_Present", "type" : "boolean", "doc" : …}
   {"name" : "COL2", "type" : [ "null", "string" ], "doc" : "...", "default" : null}
   {"name" : "COL2_Present", "type" : "boolean", "doc" : …}
   {"name" : "COL2_BeforeImage", "type" : [ "null", "string" ],"doc" : … }
   {"name" : "COL2_BeforeImage_Present", "type" : "boolean", "doc" : …}
}]
