Nice PickThe 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
Compare:vs Apache Cassandra
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
