Prominent pros & cons

PROS

Cassandra excels in handling time series data with vast amounts of writes and can achieve high performance without a single downtime due to its node-to-node ring architecture.
Its most valuable features include counter features, NoSQL schema, scalability, and high availability, making it ideal for large-scale data storage and real-time processing.
The database capabilities of Cassandra are highly regarded, with fast retrieval, large data handling capacity, and compatibility with real-time data analytics being key strengths.
Cassandra's distribution capabilities allow for flexible deployment options, such as running part in the cloud and part on-prem, offering a robust failover solution.
The scaling capabilities and non-SQL nature of Cassandra, combined with its fast write speeds and automatic recovery process, make it a top choice for distributed database systems.

CONS

Cassandra's secondary index can be problematic and may require improvement.
Data fetching performance from high-volume datasets could be enhanced in Cassandra.
There is a limitation in Cassandra's support for SQL-like ORDER BY or GROUP BY clauses.
Cassandra may need more integrated tools for maintenance, reducing dependency on third-party solutions.
The batch insertion of large data volumes in Cassandra can lead to performance issues.

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 solution doesn't have joins between tables so you need other tools for that.

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.

Cassandra can improve by adding more built-in tools. For example, if you want to do some maintenance activities in the cluster, we have to depend on third-party tools. Having these tools build-in would be e benefit.
