Overview

Data Lake Insight (DLI) software development kits (SDKs) encapsulate the RESTful APIs provided by DLI to simplify development.

DLI offers support for two types of SDKs: one is the general SDK V3, and the other is the SDK developed by DLI (including DLI SDK V1 and DLI SDK V2).

This document describes how to use the SDK developed by DLI.

**Table 1** DLI SDK types
SDK	Version	Description	How to Use
General SDK	V3	The SDK V3 APIs are automatically generated from the YAML files defining the APIs, ensuring parameter consistency with the service's own APIs. You can directly call the API functions offered by SDK V3 to submit both DLI SQL and DLI Spark jobs, streamlining the development process. The SDK you download on the API Explorer page is the universal version SDK V3.	General SDK V3
SDK developed by DLI	DLI SDK V1	SDKs developed by DLI, corresponding to the dli-sdk-x-1.x.x version in the DLI SDK installation package.	This version will be deprecated and is not recommended.
SDK developed by DLI	DLI SDK V2	SDKs developed by DLI based on the general SDK V3, corresponding to the dli-sdk-x-2.x.x version in the DLI SDK installation package. You can directly call DLI SDK V2 to submit both DLI SQL and DLI Spark jobs, streamlining the development process. Download the DLI SDK V2 installation package on the DLI management console. NOTE: Starting May 2024, new users can directly use DLI's SDK V2 without needing to have their accounts whitelisted. For users who started using DLI before May 2024, to use this function, they must submit a service ticket to have their accounts whitelisted.

The DLI SDK calls APIs using HTTPS, with certificates utilized by the server.

DLI SDK Introduction

DLI SDKs encapsulate the RESTful APIs provided by DLI to simplify development. You can directly call the API functions offered by DLI SDKs to submit both DLI SQL and DLI Spark jobs.

DLI SDKs consist of both the SDK V3 and other SDKs developed by DLI.

(Recommended )DLI SDK V3: automatically generates APIs from the YAML files defining the APIs, ensuring parameter consistency with the service's own APIs.
For details, see SDK V3.
DLI SDK (self-developed): SDKs developed by the DLI team. This manual introduces the usage of DLI's self-developed SDKs.
