HSE: Heterogeneous-Memory Storage Engine
HSEis an embeddable key-value store designed for SSDs based on NAND flash or persistent memory. HSE optimizes performance and endurance by orchestrating data placement across DRAM and multiple classes of SSDs or other solid-state storage.
HSE is ideal for powering NoSQL, Software-Defined Storage (SDS), High-Performance Computing (HPC), Big Data, Internet of Things (IoT), and Artificial Intelligence (AI) solutions.
Key Features
- Standard and advanced key-value operators
- Full transactions with snapshot-isolation spanning multiple independent key-value collections
- Cursors for iterating over snapshot views
- Data model for optimizing mixed use-case workloads in a single data store
- Flexible durability controls
- Configurable data orchestration schemes
- C API library that can be embedded in any application
Benefits
- Scales to terabytes of data and hundreds of billions of keys per store
- Efficiently handles thousands of concurrent operations
- Dramatically improves throughput, latency, write-amplification, and read-amplification versus common alternatives for many workloads
- Optionally combines multiple classes of solid-state storage to optimize performance and endurance
Getting Started

YCSB Performance Results
YCSB (Yahoo!® Cloud Serving Benchmark) is an industry-standard benchmark for databases and storage engines supporting key-value workloads. The following table summarizes several YCSB workload mixes, with application examples taken from the YCSB documentation.
YCSB Workload | Operations | Application Example |
---|---|---|
A | 50% Read; 50% Update | Session store recording user-session activity |
B | 95% Read; 5% Update | Photo tagging |
C | 100% Read | User profile cache |
D | 95% Read; 5% Insert | User status updates |
We integrated HSE with YCSB to make it easy to compare its performance and scalability to that of other storage engines for YCSB workloads. Below are throughput results from running YCSB with HSE.
For comparison, we include results from RocksDB , a popular and widely-deployed key-value store. For these YCSB workloads, HSE delivered up to nearly 6x more throughput than RocksDB.
System configuration details and additional performance results can be found in the YCSB section of the HSE Wiki.
We also integrated HSE with MongoDB® , a popular NoSQL database, to validate its benefits within a real-world storage application. Below are throughput results from running YCSB with MongoDB using HSE (MongoDB/HSE).
For comparison, we include results from MongoDB using the default WiredTiger storage engine (MongoDB/WiredTiger). For these YCSB workloads, MongoDB/HSE delivered up to nearly 8x more throughput than MongoDB/WiredTiger.
System configuration details and additional performance results can be found in the MongoDB section of the HSE Wiki.
