we are considering migrating around 200 million customer info into ES, but before doing it, I need to assess the ES hardware resource requirement to leverage the cost and profit.
The use case of these data is to filter specific groups of people to put proper ADs.
I would like to know how can I assess the resource cost based on the amount, data format and use case.
Here is a desensitized data example:
```json
