Overview

-

Data type is a basic attribute of data. It is used to distinguish different types of data. Different data types occupy different storage space and support different operations. Data is stored in data tables in the database. A data type is specified for each column of a data table. Therefore, data to be stored in a data table must comply with the attribute of the specific data type. Otherwise, errors may occur.

Data is stored in data tables in the database. Each column of a table defines the data type. During storage, data must be stored according to data types.

DLI only supports primitive data types.

Creating an OBS Table Using the DataSource Syntax

Function

Create an OBS table using the DataSource syntax.

The main differences between the DataSource and the Hive syntax lie in the supported data formats and the number of supported partitions. For details, see syntax and precautions.

-

You are advised to use the OBS parallel file system for storage. A parallel file system is a high-performance file system that provides latency in milliseconds, TB/s-level bandwidth, and millions of IOPS. It applies to interactive big data analysis scenarios.

Precautions

  • The size of a table is not calculated when the table is created.
  • When data is added, the table size will be changed to 0.
  • You can check the table size on OBS.
  • Table properties cannot be specified using CTAS table creation statements.
  • An OBS directory containing subdirectories:

    If you specify an OBS directory that contains subdirectories when creating a table, all file types and content within those subdirectories will also be included as table content.

FAQ

  • What should I do if the error message "xxx dli datasource v2 tables is only supported in spark3.3 or later version." appears when I create a DataSource table using the default queue?

    Ensure that you use Spark 3.3.1 or a later version when creating such a table. If the error message appears, use the Hive syntax to create the table. For details, see Creating an OBS Table Using the Hive Syntax.

    +
  • What should I do if the error message "xxx don`t support dli v1 table." appears when I use Spark 3.3.1 to run a Jar job?

    This error message indicates that table operations cannot be performed when Spark 3.3.1 is used to execute the Jar job. Use the Hive syntax to recreate the tables' data structure. For example, you can use [STORED AS file_format] CTAS to recreate the table and then run the job. For details, see Creating an OBS Table Using the Hive Syntax.
