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.

Amazon Aurora Serverless is an on-demand, auto-scaling configuration for Amazon Aurora. It automatically starts up, shuts down, and scales capacity up or down based on your application's needs. It enables you to run your database in the cloud without managing any database capacity.

With Aurora Serverless, you simply create a database endpoint, optionally specify the desired database capacity range, and connect your applications. You pay on a per-second basis for the database capacity you use when the database is active, and migrate between standard and serverless configurations with a few clicks in the Amazon RDS Management Console.

​Onboarding
Very quick to start, includes a free version to try things out. Might take some time due to its C8 query language.

​Scalability
Automatic, elastic scaling.

Regions
United States, Europe, Australia, Middle East.

​Security
Presents Real time log analytics, Real time Event Correlation, Real-time security information, threat & anomaly detection and event management, Graph Search & Knowledge Graphs, and more.


​

Onboarding
Good documentation that includes tutorials.

Scalability
On-demand auto scaling configuration, sharding.

Regions
US, Africa, Asia Pacific, China, South America, Middle East and Europe. The support varies across specific versions of each database engine, and across AWS Regions.

 
Backups 
Aurora backs up your cluster volume automatically and retains restore data for the length of the backup retention period. You can specify a backup retention period, from 1 to 35 days, when you create or modify a DB cluster.  Aurora backups are stored in Amazon S3.

Security
By default, Aurora Serverless v1 uses the Transport Layer Security/Secure Sockets Layer (TLS/SSL) protocol to encrypt communications between clients and your Aurora Serverless v1 DB cluster. It supports TLS/SSL versions 1.0, 1.1, and 1.2.
