Cloud Datastore

Cloud Datastore is a highly durable database that can scale automatically to handle your application’s load.

Prerequisite

1. Authentication Requirements: Before establishing a connection with Cloud Datastore, ensure you have the necessary authentication credentials, including:

   • Google Cloud Project ID.
   • Service Account Key File: Create a Service Account on the Google Cloud Console and generate a JSON key file. This key file contains the credentials required for authentication.

2. Enable Cloud Datastore API: In the Google Cloud Console, make sure that the Cloud Datastore API is enabled for your project. This API allows your application to interact with Cloud Datastore.

3. Service Account Access: Grant the Service Account associated with your application the necessary permissions to access Cloud Datastore. Assign the appropriate roles, such as Cloud Datastore User or Cloud Datastore Viewer, to the Service Account.

4. Download and Secure Key: Download the JSON key file generated for the Service Account. Safeguard this key file as it contains essential credentials for authenticating your application's access to Cloud Datastore.

3. Configure Data Input:

   • Specify the Entity Kind: Select the kind of entity you want to retrieve from Google Cloud Datastore.
   • Provide the Entity Key: Enter the key associated with the entity you wish to retrieve.

   Data Input	Description
   Namespace	Specifies the namespace under which the entity is stored. Namespace is used to logically partition data.
   Key	Unique identifier for the entity within the specified namespace and kind.
   Kind	Represents the category or type of the entity. It helps organize and group related entities together.
   Query	Defines the conditions and criteria for retrieving specific entities from the Cloud Datastore.
   Data	Displayed data fields of the retrieved entity, including properties and their corresponding values.

4. Execute and View Response:

   • Run the configured query to retrieve the entity by its key.
   • The response will contain the data associated with the specified entity key.
