+### KAFKA
+
+The `inputFormat` to load complete kafka record including header, key and
value. An example is:
+
+```json
+"ioConfig": {
+ "inputFormat": {
+ "type": "kafka",
+ "headerLabelPrefix": "kafka.header.",
+ "timestampColumnName": "kafka.timestamp",
+ "keyColumnName": "kafka.key",
+ "headerFormat":
+ {
+ "type": "string"
+ },
+ "keyFormat":
+ {
+ "type": "json"
+ },
+ "valueFormat":
+ {
+ "type": "json"
+ }
+ },
+ ...
+}
+```
+
+The KAFKA `inputFormat` has the following components:
+
+| Field | Type | Description | Required |
+|-------|------|-------------|----------|
+| type | String | This should say `kafka`. | yes |
+| headerLabelPrefix | String | A custom label prefix for all the header
columns. | no (default = "kafka.header.") |
+| timestampColumnName | String | Specifies the name of the column for the
kafka record's timestamp.| no (default = "kafka.timestamp") |
+| keyColumnName | String | Specifies the name of the column for the kafka
record's key.| no (default = "kafka.key") |
+| headerFormat | Object | headerFormat specifies how to parse the kafka
headers. Current supported type is "string". | no |
+| keyFormat | Object | keyFormat can be any existing inputFormat to parse the
kafka key. See [the below
section](../development/extensions-core/kafka-ingestion.md#specifying-data-format)
for details about specifying the input format. | no |
+| valueFormat | Object | valueFormat can be any existing inputFormat to parse
the kafka value payload. See [the below
section](../development/extensions-core/kafka-ingestion.md#specifying-data-format)
for details about specifying the input format. | yes |
