When comparing Orchestrate vs Apache Cassandra, the Slant community recommends Orchestrate for most people. In the question“What are the best databases to use for Node.js applications?” Orchestrate is ranked 12th while Apache Cassandra is ranked 13th. The most important reason people chose Orchestrate is:
Orchestrate was built for scale. Orchestrate is a full-fledged distributed data system, provided as a multi-tenant service. There is no need to manage finite server resources like disk space, CPU, or memory
Ranked in these QuestionsQuestion Ranking
Pros
Pro Effortless/Automatic Scaling
Orchestrate was built for scale. Orchestrate is a full-fledged distributed data system, provided as a multi-tenant service. There is no need to manage finite server resources like disk space, CPU, or memory
Pro Already set up for you
Orchestrate is a Database-as-a-Service, so there is no downloading, installation, or any other administration. It also makes configuration management and deployment easy.
Pro Great Node.js support
Orchestrate.js is a first class client for Node.js applications
Pro Fault Tolerance Baked In
As a DBaaS, Orchestrate manages replicas and sharding across multiple machines. Additionally, daily backups are managed by the company.
Pro Multiple Query types at Low Latencies
No other database provides Full-Text-Search, Time-Series, Graph, and Key/Value APIs. Moreover, as a DBaaS, the queries are pre-optimized for low latencies. Consistently under 10ms for any query.
Pro Highly available cluster
Once setup database is set up, it becomes highly available without any downtime.
Pro Highly scalable
Cassandra is very scalable and achieves the highest throughput for the maximum number of nodes compared to other alternatives. Unfortunately this also brings rather high write and read latencies.
Pro Familiar to developers used to SQL
The query language that Cassandra uses (CQL) is similar to SQL even though it's a NoSQL database.
Pro Rapid writing and lightning-fast reading
After measuring the read/write performance values on one server, you can simply calculate how many more servers you should add to the cluster to reach the required performance levels, and scale easily.
Cons
Con Data are not on your server
Since it's a DBaaS, your data are completely on their server. It cannot be run on your server. Backup is handled by them as well, which may be good or not depending on your needs.
Con Not Open Source
Orchestrate is not an open source solution.
Con No JOINS
Cassandra has no support for JOINS.
