Macrometa's architecture is a geo distributed event source with a materialized view engine and CRDT based replication. To achieve consistency in replication, Macrometa provides an adaptive model that allows developers to define the consistency level with fine grained granularity to achieve different levels of isolation and consistency depending on their needs.

Macrometa's team of scientists and engineers have incorporated leading edge ideas from distributed systems and concurrent databases that incorporate technologies like Conflict Free Replicated Datatypes (CRDT) to create a new highly secure, high performance, low latency data infrastructure.

MongoDB is a serverless, distributed database orientated towards documents, in other words, saving data in BSON documents instead of registries, making it much more expressive and powerful. It's got all the advantages and usages of a relational database, but being more flexible and dynamic.

The MondoDB Atlas is a database on a global cloud created with modern applications in mind, and it's distributed and safe by default, alongside being managed in AWS, Google Cloud and Azure.

​

Onboarding

Great documentation to start off quickly, with a free plan that's very quick to access. Has a wide amount of resources and guides to learn about it.

Scalability

Automatic, and scalable both horizontally (sharding) and vertically.

Regions​

MongoDB Atlas supports  the following regions: Americas, Asia Pacific, Europe, Middle East and Africa. The choice of cloud provider and region affects network latency for clients accessing your database deployment and the cost of running the database deployment. For clusters, this choice also affects the configuration options for the available cluster tiers. The region refers to the physical location of your MongoDB database deployment.

Backup

​MongoDB Atlas, the official MongoDB cloud service, provides 2 fully-managed methods for backups:

• ​Continuous Backups, which take incremental backups of data in your cluster, ensuring your backups are typically just a few seconds behind the operational system. Atlas continuous backups allow you to restore from stored snapshots or from a selected point in time within the last 24 hours. You can also query a continuous backup snapshot.
• Cloud Provider Snapshots, which provide localized backup storage using the native snapshot functionality of the cluster's cloud service provider.

Security

​MongoDB provides various features, such as authentication, access control, encryption, to secure your MongoDB deployments. Some key security features include: Authentication, SCRAM, Role-Based Access Control, Transport Encryption, among others.

The Macrometa Global Data Network is based on cutting edge computer science incorporating new ideas and research in the areas of messaging, event processing, data consistency and replication.

MongoDB is a document database with the scalability and flexibility that you want with the querying and indexing that you need. MongoDB’s document model is simple for developers to learn and use, while still providing all the capabilities needed to meet the most complex requirements at any scale. 

• Rich on JSON Documents
• Allows arrays and nested items as values
• Rich and expressive consulting language
• Filter and order on any field, regardless of the way it's inserted in the document
• Full ACID transactions
• Allows for combinations on inquiries
• Completely automatized
• Security Copy
• Global Clusters
