Cases when MongoDB does not work

1. When the dataset size exceeds the available memory: MongoDB relies heavily on memory-mapped files to provide efficient data access. However, if the dataset size grows beyond the available memory, it can lead to frequent page faults and reduced performance. In such cases, it is recommended to either scale up the hardware resources or shard the dataset across multiple servers.
2. When there is a need for complex joins and transactions: MongoDB is a NoSQL database that prioritizes scalability and performance over strict consistency. As a result, it does not support complex join operations or multi-document transactions in the same way as traditional relational databases. While MongoDB provides some mechanisms to handle relationships between documents, if your use case heavily relies on complex joins or ACID transactions, a relational database might be a better fit.
3. When there is a requirement for real-time analytics: MongoDB is designed for operational data storage and retrieval rather than real-time analytics. Although it provides aggregation framework and map-reduce capabilities, it may not offer the same level of performance and flexibility as dedicated analytics databases like Apache Spark or Apache Druid. If your application requires extensive real-time analytics, it might be worth considering specialized analytics tools alongside MongoDB.
4. When the data schema is likely to change frequently: MongoDB’s flexible schema-less nature allows for easy changes to the data structure. However, if the data schema is expected to evolve frequently and unpredictably, it can introduce challenges in maintaining data integrity and consistency. In such cases, a relational database with a fixed schema and strong data validation might be a more suitable choice.
5. When strong ACID guarantees are required: MongoDB provides a level of data consistency through replica sets and write acknowledgments. However, it does not offer full ACID (Atomicity, Consistency, Isolation, Durability) guarantees across multiple operations. If your application demands strict ACID compliance, especially for complex transactions involving multiple documents, a traditional relational database might be a better choice.
