QLDB is a database similar with apache Kafka database. It's a Ledger database. You can use it to reduce the stress of rds or dynamodb when there are a lot of players and update requests.

    エンジン プラグイン
    この製品には、コード プラグインが含まれており、ビルド済みのバイナリと Unreal Engine に統合される全ソースコードが完備されています。任意のエンジン バージョンにインストールし、プロジェクト毎に有効化することが可能です。

Note: This plugin is recommended for more advanced users. 


You can use this plugin to store players' activities. For example, how many times does the player open the store page in your game? or how often did they pay a gamble box? Players may lie in research but data won't lie.

You can upload the user activities to QLDB to analyze why the player did not open the store page or why they did not purchase the gamble box. if you upload these user activities to dynamodb or rds, it will block the net traffic because DynamoDB and RDS can't handle update request in high throughput rate and if it can, the cost will be extremely expensive.
