We compared ScyllaDB and MongoDB across several key parameters based on reviews from actual users of both databases. While both are mature solutions, ScyllaDB's technical architecture gives it performance and scalability advantages for demanding workloads. But MongoDB provides a wider range of deployment options more aligned with early-stage growth. Below is a summary of our findings:
Based on user experiences, ScyllaDB's multiprimary design provides very high performance at scale, with solid throughput and low latency suited for data-intensive workloads. MongoDB offers more implementation flexibility but lags in scalability. For large-scale distributed applications, ScyllaDB has advantages in speed, simplicity and efficiency.
"I value the API integrations."
"We haven't had any issues with stability."
"MongoDB is fast and efficient."
"One of the first things I noticed when I had my first experience with MongoDB was how easy it was to use. I was expecting more difficulties or at least some challenges, but it was very, very easy to use. It's great technology, performs well, and is very convenient."
"In our case, it is most important to have redundancy."
"The most valuable features of MongoDB are the variety of translations available and the ability to deploy it on the cloud is useful. The cloud users can access the data, work on the data, and if they want to import or manipulate some data they can."
"It's easy to add and remove things in MongoDB. You can alter the tables. MongoDB is faster at reading, slower at writings."
"MongoDB is extremely developer-friendly because when you are starting, there is very little time needed upfront in terms of planning."
"The performance aspects of Scylla are good, as always... A good point about Scylla is that it can be used extensively."
"It is lightweight, and it requires less infrastructure."
"MongoDB should not be used for reporting, analytics, or number-crunching tasks."
"Its security features can be better. Sometimes, my higher authority says that we are not going to use MongoDB because it doesn't provide that much security for the RDBMS or relational data that we use for transactions. Instead of MongoDB, we will use Oracle Database because for a transactional service, you have to rely on RDBMS ACID properties. I would love to work on MongoDB by using my mobile phone. When I am working remotely or traveling and have some instances deployed on my server, I should be able to check through my mobile whether all the data is being pulled. GitHub has a similar feature, where it lets you read from the laptop, and you can also pull and push with your mobile phone. I would request MongoDB to provide such a feature. Basically, I want a mobile version for both iOS and Android versions."
"It should have GUI for managing clusters. MongoDB needs a more powerful GUI to manage clusters and make switchovers. Currently, there is no good, free tool to check the replication to find out if there is a gap."
"The performance could be faster."
"The user interface is not as friendly as Oracle, which is something that can be improved."
"It has certain limitations when it comes to handling hierarchical data, enforcing relationships, and performing complex joins, which should be taken into account when designing databases for applications with intricate data requirements."
"It could be more stable. It would be better if it were more user-friendly like Oracle, which is very easy. For example, creating an index is simple in Oracle. In MongoDB, it's quite challenging to do that. Performance could be better. It's fast and good, but you cannot put every application that you would like to in MongoDB."
"We'd like technical support to respond faster to queries."
"Data export, along with how we can purchase the data periodically, needs to be improved so that the storage is within control. Then, we could optimize it even better."
"The documentation of Scylla is an area with shortcomings and needs to be improved."
MongoDB is ranked 1st in NoSQL Databases with 70 reviews while ScyllaDB is ranked 6th in NoSQL Databases with 2 reviews. MongoDB is rated 8.2, while ScyllaDB is rated 7.6. The top reviewer of MongoDB writes "Lightweight with good flexibility and very fast performance for searching data". On the other hand, the top reviewer of ScyllaDB writes "A solution that offers good performance and flexibility to its users". MongoDB is most compared with InfluxDB, Couchbase, Cassandra, Oracle NoSQL and Oracle Berkeley DB, whereas ScyllaDB is most compared with Cassandra, Couchbase, Apache HBase, Aerospike Database 7 and InfluxDB.
