### File Scan Task Serialization
-File scan task is serialized as a JSON object according to the following table.
-
-| Metadata field |JSON representation|Example|
-|--------------------------|--- |--- |
-| **`schema`** |`JSON object`|`See above, read schemas instead`|
-| **`spec`** |`JSON object`|`See above, read partition specs
instead`|
-| **`data-file`** |`JSON object`|`See above, read content file instead`|
-| **`delete-files`** |`JSON list of objects`|`See above, read content file
instead`|
-| **`residual-filter`** |`JSON object: residual filter
expression`|`{"type":"eq","term":"id","value":1}`|
+There could be different implementations of file scan task,
+e.g., `BaseFileScanTask` and `StaticDataTask` in Java.
+A enum `task-type` field is needed to distinguish different task types.
+
+| Metadata field | JSON representation | Example
|
+|-----------------|---------------------|---------------------------------------------------------------------------------------|
+| **`task-type`** | `JSON string` | `base-file-task`,
`static-data-task`. Absence of this field should be interpreted as
`base-file-task` |
