We performed a comparison between Cassandra and ClickHouse based on real PeerSpot user reviews.
Find out what your peers are saying about Elastic, Meta, Chroma and others in Vector Databases."I am satisfied with the performance."
"Cassandra has some features that are more useful for specific use cases where you have time series where you have huge amounts of writes. That should be quick, but not specifically the reads. We needed to have quicker reads and writes and this is why we are using Cassandra right now."
"The most valuable features are the counter features and the NoSQL schema. It also has good scalability. You can scale Cassandra to any finite level."
"Our primary use case for the solution is testing."
"Can achieve continuous data without a single downtime because of node to node ring architecture."
"The time series data was one of the best features along with auto publishing."
"The most valuable features of Cassandra are the NoSQL database, high performance, and zero-copy streaming."
"The most valuable feature of Cassandra is its fast retrieval. Additionally, the solution can handle large amounts of data. It is the quickest application we use."
"If you have a real-time basis, you should take a look at ClickHouse because it works on a vector database, and the querying is super fast compared to traditional databases."
"Fine-tuning was a bit of a challenge."
"Depending upon our schema, we can't make ORDER BY or GROUP BY clauses in the product."
"The secondary index in Cassandra was a bit problematic and could be improved."
"The solution is not easy to use because it is a big database and you have to learn the interface. This is the case though in most of these solutions."
"The solution is limited to a linear performance."
"There could be more integration, and it could be more user-friendly."
"Interface is not user friendly."
"It can be difficult to analyze what's going on inside of the database relative to other databases. It can also be difficult to troubleshoot sometimes."
"One issue is that you need persistent volumes. Otherwise, if one system goes down, you lose data in that cluster."
