Hive Data Store uses NoSQL Cloud Database to synchronize and store the data for use on the client, such as the components of the game and the settings information. Using this service is a good solution for the games based on the client or if it needs real-time updates between clients.
Hive Data Store has the following features:
- The data is stored in the storage separately of each game.
- All data is encrypted and delivered safely.
- Unlike SQL database, NoSQL Cloud Database has no tables and rows, and the data is stored in documents consisting of collections.
- Stores and documented data as key–value pairs.
- Optimizes for storing the collection that consists of multiple documents.
- For the precautions of designing key–value, see the Operation > Game Data Store guide from Hive Developers.
Add Data
You can add data to the Data Store in one pair of a key–value or multiple pairs of map format at once. After a request, true or false is returned.
The followings are sample codes to add data of a key–value pair.

Get Data
There are two ways to get your data one or all at once, and you also can get all user data corresponding to a key you requested. The three ways of getting data are as follows:
-
- Get one of my data
- Get all my data
- Get all data using key
Check out the following sample codes for each way.
The followings are sample codes to get one of my data.
