HarperDB Systemeigenschaften

HarperDB is the first distributed database with hybrid SQL & NoSQL functionality & a REST API. Known as a structured object store with SQL capabilities, or NewSQL. HarperDB is focused on speed, ease of use, & flexibility. As a distributed database, HarperDB leverages a logical structure enabling ACID compliant efficient storage & retrieval without inconsistency, race conditions, or utilizing in-memory indexing. HarperDB is fully indexed & runs on any device from edge to cloud. HarperDB Cloud is their database-as-a-service offering.

Storage Algorithm 

HarperDB's unique storage algorithm built on top of LMDB enables HarperDB to ingest JSON documents & relational data in a single product.  

SQL & NoSQL 

Insert JSON, query with performant SQL including joins & full CRUD operations. Regardless of how data is ingested, data is stored according to the HarperDB data model & can be queried via SQL or NoSQL.

Dynamic Schema

Ingest any type of data at scale. The schema reflexively creates attributes on ingest, creating new database fields as they are sent. Users can ingest unstructured data & retain SQL functionality.

Clustering & Replication

HarperDB leverages a publish/subscribe model to move data between instances. This enables configurable bi-directional, table-level replication. HarperDB’s clustering is fault tolerant, peer-to-peer, provides table level replication, has a globally shared schema, & enables distributed computing.

REST API 

All database operations are available via a single endpoint HTTP API with a stateless microservices architecture. See API documentation in our Postman Collection.

Management Studio 

The HarperDB Studio enables users to manage both self-hosted & HarperDB Cloud managed instances. The Studio includes Marketplace & resources like SDKs, connectors, drivers, example code, & video tutorials..

Access

HarperDB is cross-platform, running natively on Linux, MacOS & Microsoft WSL2. It can be deployed via Docker container, & is available for download via npm or as a managed service via HarperDB Studio. HarperDB also offers images on DigitalOcean & AWS. 

The HarperDB Studio is web-based & can be accessed via anything with a web browser.

Role Based Security

HarperDB uses a Role-Based Access Control (RBAC) framework to manage access to HarperDB instances. Visit the documentation. 

ACID Transactions

HarperDB is fully ACID compliant allowing users to follow the universal standard of SQL query language at the standards of atomicity, consistency, isolation, & durability. 

Industry Standard Interfaces & Drivers

HarperDB leverages standard interfaces and provides numerous drivers.

By combining the functionality of the best SQL, NoSQL, and NewSQL products on the market into one powerful tool, HarperDB makes data management easier and more cost effective. Effectively enabling SQL on JSON, users no longer have to choose a database based on the structure of their data. With HarperDB’s speed, flexibility, and customization, you can reduce time spent on database maintenance and reduce the number of systems needed to achieve your end goal. HarperDB is allowing developers from relational backgrounds to use their existing knowledge with SQL with a database that also allows their team to use NoSQL from the same data model (and vice versa).

Accessed via a simple REST API, HarperDB is super easy to use and built for developers and technology leaders of any skill level. Because HarperDB can run truly anywhere and ingest any type of data at scale, organizations can avoid cloud lock-in, latency, and complexity. From large industrial companies looking to activate a hybrid cloud or data warehouse, to developers looking to enable rapid development and integration, there are many applications that HarperDB can handle consistently and efficiently. 

HarperDB Cloud is fully managed and hosted to maximize operational efficiency and reduce cost and complexity.

Performance

On average, HarperDB was 37X faster than MongoDB, 6.8X faster than InfluxDB on writes, and 581% faster than SQLite. HarperDB scales out-of-the-box for concurrent operations, & has simplified work on database administration & maintenance. See the benchmarks.

Use cases where HarperDB is a better fit than other solutions include:

• Rapid app development
  
• Edge computing
  
• Hybrid edge/cloud and distributed computing 
  
  • Data pipeline that runs across multiple clouds with real-time data synchronization
    
  • Extend data fabric to edge data centers
    
  • Move serverless functions and API to the edge 
    
  • Eliminate vendor lock-in, reduce cost, lower latency, gain real-time capability
    
• IoT
  
• Integration
  
• Real-time analytics
  
• Machine learning
  
• Reporting and charting

HarperDB enables developers and technology leaders to:

• Leverage existing AWS, GCP, or Azure Infrastructure and migrate API to HarperDB easily, quickly, with little disruption
  
• Lower costs, avoid “vendor lock-in” and provide a low-latency API 
  
• Provide geo-redundant, cross-cloud DR and high availability architecture
  
• Increase development velocity 
  
• Reduce application latency 
  
• Provide a better “end-user” experience 
  
• Simplify architecture 
  
• Have more negotiating power with AWS, GCP, and Azure 
  
• Improve app speed and performance

A few highlighted customers include: US Army, US Airforce, Chelan PUD, TATA, & Lumen. ​

HarperDB follows a freemium/premium model. A database is only as powerful as it is flexible, so we created a simple pricing model based on the memory of a machine. Pricing is per instance and is based on provisioned memory. For self-hosted instances, HarperDB will restrict itself to use only the RAM afforded by its license.

HarperDB includes a powerful free forever tier, enabling users to spin up a 0.5 GB RAM instance at no cost. The paid model starts at 1 GB RAM, at $19.99/month for HarperDB Cloud and $215.89/year for self-hosted.
