The distributed database that scales like a dream but queries like a nightmare.

Full Rankings

The distributed database that scales like a dream but queries like a nightmare.

Pros

  • +Massive horizontal scalability with no single point of failure
  • +Excellent write performance for time-series and IoT data
  • +Flexible schema design that evolves without downtime

Cons

  • -Complex querying with limited JOIN support
  • -Steep learning curve for data modeling and tuning

Bigtable's open-source cousin. Great for massive, sparse data if you don't mind wrestling with Hadoop.

Pros

  • +Massive scalability on Hadoop HDFS
  • +Real-time random read/write access to petabytes
  • +Strong consistency and fault tolerance
  • +Sparse data storage without wasted space

Cons

  • -Steep learning curve with complex Hadoop ecosystem dependencies
  • -Poor performance for small datasets or complex queries

SQL's rebellious cousin that ditched joins for distributed glory, but still can't handle your relational baggage.

Pros

  • +Familiar SQL-like syntax reduces learning curve for Cassandra newcomers
  • +Optimized for Cassandra's column-family model with built-in support for partitions and clustering keys
  • +Enables schema definition and data manipulation in a distributed NoSQL environment

Cons

  • -Lacks joins and complex transactions, forcing denormalization and application-level logic
  • -Limited query flexibility compared to full SQL, often requiring careful data modeling upfront
