Cassandra vs MongoDB vs couchdb vs redis vs Riak vs hbase vs membase vs neo4j
While SQL databases are insanely useful tools, their monopoly ~ 15 years is coming to an end. And it was just time: I can't even count the things that were forced into relational databases, but never really fitted them.

for JavaScript expression queries
Arbitrary JavaScript functions can be executed on the server side
Update-in-place support is better than couchdb
Memory-to-file mapping when data is stored
Performance concerns outweigh the requirements for functionality
It is recommended to turn on the log function (parameter –journal)

Best application scenarios:Suitable for applications with fast data changes and database size (suitable for memory capacity.
For example:Stock price, data analysis, real-time data collection, and real-time communication.
(Note 3: master-slave replication: if only one server processes all replication requests at the same time, this is called master-slave replication, generally, applications are deployed in Server clusters that require high availability .)
