+## Description
+
+hudi_meta table-valued-function(tvf), using for read hudi metadata, operation
history, timeline of table, instant state etc.
+
+## Syntax
+
+```sql
+hudi_meta(
+ "table" = "ctl.db.tbl",
+ "query_type" = "timeline"
+ ...
+ );
+```
+
+**parameter description**
+
+Each parameter in hudi_meta tvf is a pair of `"key"="value"`.
+
+Related parameters:
+- `table`： (required) Use hudi table name the format `catlog.database.table`.
+- `query_type`： (required) The type of hudi metadata. Only `timeline` is
currently supported.
+
+## Example
+
+Read and access the hudi tabular metadata for timeline.
+
+```sql
+select * from hudi_meta("table" = "ctl.db.tbl", "query_type" = "timeline");
+
+```
+
+Can be used with `desc function` :
+
+```sql
+desc function hudi_meta("table" = "ctl.db.tbl", "query_type" = "timeline");
+```
+
+## Keywords
+
+ hudi_meta, table-valued-function, tvf
+
+## Best Practice
+
+Inspect the hudi table timeline :
+
+```sql
+select * from hudi_meta("table" = "hudi_ctl.test_db.test_tbl", "query_type" =
"timeline");

+## 描述
+
+hudi_meta 表函数（table-valued-function,tvf），可以用于读取 hudi
表的各类元数据信息，如操作历史、表的时间线、文件元数据等。
+
+## 语法
+
+```sql
+hudi_meta(
+ "table" = "ctl.db.tbl",
+ "query_type" = "timeline"
+ ...
+ );
+```
+
+**参数说明**
+
+hudi_meta 表函数 tvf 中的每一个参数都是一个 `"key"="value"` 对。
+相关参数：
+- `table`： (必填) 完整的表名，需要按照目录名。库名。表名的格式，填写需要查看的 hudi 表名。
+- `query_type`： (必填) 想要查看的元数据类型，目前仅支持 timeline。
+
+## 举例
+
+读取并访问 hudi 表格式的 timeline 元数据。
+
+```sql
+select * from hudi_meta("table" = "ctl.db.tbl", "query_type" = "timeline");
+
+```
+
+可以配合`desc function`使用
+
+```sql
+desc function hudi_meta("table" = "ctl.db.tbl", "query_type" = "timeline");
+```
+
+
+## 最佳实践
+
+查看 hudi 表的 timeline

+select * from hudi_meta("table" = "hudi_ctl.test_db.test_tbl", "query_type" =
"timeline");

+## Description
+
+hudi_meta table-valued-function(tvf), using for read hudi metadata, operation
history, timeline of table, instant state etc.
+
+## Syntax
+
+```sql
+hudi_meta(
+ "table" = "ctl.db.tbl",
+ "query_type" = "timeline"
+ ...
+ );
+```
+
+**parameter description**
+
+Each parameter in hudi_meta tvf is a pair of `"key"="value"`.
+
+Related parameters:
+- `table`： (required) Use hudi table name the format `catlog.database.table`.
+- `query_type`： (required) The type of hudi metadata. Only `timeline` is
currently supported.
+
+## Example
+
+Read and access the hudi tabular metadata for timeline.
+
+```sql
+select * from hudi_meta("table" = "ctl.db.tbl", "query_type" = "timeline");
+
+```
+
+Can be used with `desc function` :
+
+```sql
+desc function hudi_meta("table" = "ctl.db.tbl", "query_type" = "timeline");
+```
+
+## Keywords
+
+ hudi_meta, table-valued-function, tvf
+
+## Best Practice
+
+Inspect the hudi table timeline :
+
+```sql
+select * from hudi_meta("table" = "hudi_ctl.test_db.test_tbl", "query_type" =
"timeline");

syntax to query the Hudi table will throw an error.

## Incremental Read
Incremental Read can query the data changed between startTime and endTime, and
the returned result set is the final state of the data at endTime.
