When comparing MongoDB vs Orchestrate, the Slant community recommends MongoDB for most people. In the question“What are the best databases to use for Node.js applications?” MongoDB is ranked 5th while Orchestrate is ranked 12th. The most important reason people chose MongoDB is:
MongoDB queries can be very fast because the data is usually all in one place and can easily be retrieved in a single lookup. But this is true only when the data is truly a document. When it's trying to emulate a relational model it starts to become really slow because it may have to perform many independent queries to retrieve a single document.

Pros
Pro Great speed
MongoDB queries can be very fast because the data is usually all in one place and can easily be retrieved in a single lookup. But this is true only when the data is truly a document. When it's trying to emulate a relational model it starts to become really slow because it may have to perform many independent queries to retrieve a single document.
Pro Perfect documentation and tutorials
Miles above other databases in educational resources.
Pro Uses JSON
As Node.js uses JavaScript there's no need to map the returned JSON data from MongoDB, as JavaScript is a superset of JSON. Essentially solving object-relational impedance mismatch by its very nature. Working with JSON is also easier overall as it more easily fits into how you would represent data on the client.
Pro Doesn't require a unified data structure
Mongo is very flexible in that it doesn't require a unified data structure across all objects. So it's rather easy to use.
Pro Easy to scale
MongoDB has powerful sharding and scaling capabilities for when the data stored in the database gets so large that a single machine may not be able to store all of it. Sharding solves this problem through horizontal scaling. Mongo gives developers the ability to easily and painlessly add or remove as many machines as needed.
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.
Cons
Con Reported to lose or corrupt data
MongoDB is famously known for leaking and losing data over time.
Con Document Stores may be not suited for relational data
MongoDB has no JOIN, all relations are supposed to be resolved client-size which entails additional requests to the server.
Con Need many search features
Though it is possible to index and search text in documents in MongoDB 4.0 in multiple languages. The indexing and search is not as powerful as for example Elastic Search. For instance not being able to search for only parts of words.
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.
