Creating a LakeFormation Instance and a Client Connection

Preparing a User

If you use LakeFormation for the first time, create a user and grant permissions to the user by referring to Preparations.

This section demonstrates the entire process of using LakeFormation. You need to complete the following preparations in advance:

• An IAM service user and user group for authorization have been created in IAM, and the user has been associated with the user group.
• A parallel file system has been created in OBS, and a folder for mapping data tables has been created in the file system.
• You have created an agency required for interconnecting with LakeFormation. For example, if you plan to interconnect MRS clusters with LakeFormation, create an agency by referring to Preparations.
