Harper overview

What is Harper?

HarperDB is the first distributed database with hybrid SQL and NoSQL functionality and a REST API. Known as a structured object store with SQL capabilities. Being a read/write optimized solution, a single node of HarperDB can simultaneously handle 20k writes per second and 120k reads per second.

HarperDB's features include data replication across the globe in under 100ms, responds in milliseconds, integrates API and database functionality into a single product, can be deployed anywhere (local, edge, colo, and/or in the cloud), and more. HarperDB uses role-based, attribute-level security to ensure that users can only gain access to the data they’re supposed to be able to access.

Cons
“It was slightly confusing trying to integrate this with a flask application at first.”

James E.

Data Scientist

“I was used to specifying which data type will be in each column but you don't have to do that for Harper DB which could give problem to the user.”

“I think of moving away from HarperDB due to this reason. 1 GB storage of DB and only one instance allowed, I mean it's too low.”
