-**Description of Object Data Type:**
-
-Since V2.0.8-beta, the `iTableSession.insert(Tablet tablet)` interface supports splitting a single Object-class file into multiple segments and writing them sequentially in order. When the column data type in the Tablet data structure is **`TSDataType.Object`**, you need to use the following method to populate the Tablet:
-
-```Java
-/*
-rowIndex: row position in the tablet
-columnIndex: column position in the tablet
-isEOF: whether the current write operation contains the last segment of the Object file
-offset: starting offset of the current write content within the Object file
-content: byte array of the current write content
-Note: When writing, ensure the total length of all segmented byte[] arrays equals the original Object size, 
-otherwise it will cause incorrect data size.
-*/
-void addValue(int rowIndex, int columnIndex, boolean isEOF, long offset, byte[] content)
-```
-
-During queries, the following four methods are supported to retrieve values:
-`Field.getStringValue`, `Field.getObjectValue`, `SessionDataSet.DataIterator.getObject`, and `SessionDataSet.DataIterator.getString`.
-All these methods return a String containing metadata in the format:
-`(Object) XX.XX KB` (where XX.XX KB represents the actual object size).

-### 1.7 Writing Object Type
-
-To avoid oversized Object write requests, values of **Object** type can be split into segments and written sequentially. In SQL, the `to_object(isEOF, offset, content)` function must be used for value insertion.
-
-> Supported since V2.0.8-beta
-
-**Syntax:**
-
-```SQL
-INSERT INTO tableName(time, columnName) VALUES(timeValue, TO_OBJECT(isEOF, offset, content));
-```  
-
-**Parameters:**
-
-| Name    | Data Type          | Description                                                                 |
-|---------|--------------------|-----------------------------------------------------------------------------|
-| isEOF   | BOOLEAN            | Whether the current write contains the last segment of the Object          |
-| offset  | INT64              | Starting offset of the current segment within the Object                   |
-| content | Hexadecimal (HEX)  | Content of the current segment                                             |
-
-**Examples:**
-
-Add an Object-type column `s1` to table `table1`:
-
-```SQL
-ALTER TABLE table1 ADD COLUMN IF NOT EXISTS s1 OBJECT FIELD COMMENT 'object type';
-```
-
-1. **Non-segmented write**
-
-```SQL
-INSERT INTO table1(time, device_id, s1) VALUES(NOW(), 'tag1', TO_OBJECT(TRUE, 0, X'696F746462'));
-```
-
-2. **Segmented write**
-
-```SQL
--- First write: TO_OBJECT(FALSE, 0, X'696F');
-INSERT INTO table1(time, device_id, s1) VALUES(1, 'tag1', TO_OBJECT(FALSE, 0, X'696F'));
-
--- Second write: TO_OBJECT(FALSE, 2, X'7464');
-INSERT INTO table1(time, device_id, s1) VALUES(1, 'tag1', TO_OBJECT(FALSE, 2, X'7464'));
-
--- Third write: TO_OBJECT(TRUE, 4, X'62');
-INSERT INTO table1(time, device_id, s1) VALUES(1, 'tag1', TO_OBJECT(TRUE, 4, X'62'));
-```
-
-**Notes:**
-
-1. If only partial segments of an Object are written, querying the column will return `NULL`. Data becomes accessible only after all segments are successfully written.
-2. During segmented writes, if the `offset` of the current write does not match the current size of the Object, the write operation will fail.
-3. If `offset=0` is used after partial writes, the existing content will be overwritten with new data.
