What is MongoDB not good for?
Nowadays, there are very few applications that actually require transactions.
MongoDB, unfortunately, does not support transactions.
So if you need to update more than one document or collection per user request, don’t use MongoDB.
It may lead to corrupted data, as there is no ACID guarantee..
How does MongoDB improve query performance?
Optimize Query PerformanceCreate Indexes to Support Queries.Limit the Number of Query Results to Reduce Network Demand.Use Projections to Return Only Necessary Data.Use $hint to Select a Particular Index.Use the Increment Operator to Perform Operations Server-Side.
Is MongoDB worth learning 2020?
The only restriction with this is supported data structures. MongoDB is comparatively faster as well. It is also very flexible and is an excellent database for companies considering scaling. Capable of handling a huge collection of data, MongoDB is used by extremely large teams.
Is Redis faster than MongoDB?
MongoDB is schemaless, which means that the database does not have a fixed data structure. This means that as the data stored in the database gets larger and larger, MongoDB is able to operate much faster than Redis. Redis is only significantly faster when the stored data is relatively small in size.
Is MongoDB faster than MySQL?
Performance and Speed It is magically faster because it allows users to query in a different manner that is more sensitive to workload. Developers note that MySQL is quite slower in comparison to MongoDB when it comes to dealing with large databases. It is unable to cope with large and unstructured amounts of data.
Is MongoDB slower than SQL?
MongoDB is almost 100 times faster than traditional database system like RDBMS, which is slower in comparison with the NoSQL databases. There is no support for complex joins in MongoDB, but RDBMS supports complex joins, which can be difficult to understand and take too much time to execute.
How much RAM does MongoDB need?
approximately 1GBMongoDB requires approximately 1GB of RAM per 100.000 assets. If the system has to start swapping memory to disk, this will have a severely negative impact on performance, and should be avoided.
Is MongoDB good to learn?
Absolutely Yes. MongoDB although clearly the favorite is just one of the many commonly used NoSQL DBs. So, yes you should learn it, not just it, but all NoSQL DB systems because I’m of the opinion that Web technologies are rapidly evolving today, standards are no longer standards for more than 6 months.
What are the disadvantages of MongoDB?
Disadvantages of MongoDB There are a few disadvantages of the MongoDB NoSQL database as well. MongoDB uses high memory for data storage. There is a limit for document size, i.e. 16mb. There is no transaction support in MongoDB.
Can MongoDB replace MySQL?

Can MongoDB handle big data?
Because of its features, MongoDB is The database for Big Data processing. MongoDB, the open-source NoSQL database, was recently named “Database Management System of the Year” by DB-Engines with a good reason, as NoSQL databases are generally better-suited for processing Big Data than RDBMS.
Is MongoDB dead?
