    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

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.
