Choosing the Right AEM Persistence Mechanism: FileDataStore, TarMK, or MongoMK?

[aem101]

Trying to understand the differences between AEM persistence mechanisms with FileDataStore, AEM with TarMK, and AEM with MongoMK. Can you help me with some basic guidance?

1. When to Use Which: In what situations should I consider using AEM with FileDataStore, AEM with TarMK, or AEM with MongoMK? What are the typical scenarios for each?

2. Performance and Memory: Are there any performance or memory usage differences I should be aware of between these options?

3. Scalability: How do these options handle scaling up my AEM system? Any tips for planning scalability?

4. Cost Considerations: Are there cost factors I should keep in mind when making this decision?

I'd appreciate any insights or real-world examples you can provide to help me grasp these concepts better. Thank you!
