eXtremeDB is a high-performance, low-latency, ACID-compliant embedded database management system using an in-memory database system (IMDS) architecture and designed to be linked into C/C++ based programs. It works on Windows, Linux, and other real-time and embedded operating systems.
History
eXtremeDB was introduced in 2001 by McObject LLC, targeting
Later editions targeted the high-performance non-embedded software market, including capital markets applications (algorithmic trading, order matching engines) and real-time caching for Web-based applications, including social networks and e-commerce.[4]
Product features
Core eXtremeDB engine
eXtremeDB supports the following features across its product family.[5]
Application programming interfaces
- A type-safe, native, navigational C/C++ API
- JDBCAPI (included in eXtremeSQL edition)
- Native C# (.NET) API
- Java Native Interface (JNI)
- Python
Database indexes
- B-tree
- R-tree
- Radix tree or Patricia trie
- k-d tree
- Hash table
- Trigram index
- Custom indexes
Concurrency mechanisms
eXtremeDB supports multiple concurrent users, offering ACID-compliant transactions (as defined by Jim Gray[6]) using either of two transaction managers: a multiple-reader, single writer (MURSIW) locking mechanism, or multiversion concurrency control (MVCC) transaction manager (optimistic non-locking model).[7][8]
Supported data types
eXtremeDB can work with virtually all
Security
- Page-level cyclic redundancy checking (CRC)
- AES encryption
- Secure Sockets Layer
Optional features
Distributed database management abilities
The eXtremeDB
Hybrid storage
eXtremeDB Fusion edition provides the option of persistent storage (disk or flash) for specific tables, via a database schema notation.[11]
Transaction logging
eXtremeDB Transaction Logging edition records changes made to the database and uses this log to recover in the event of device or system failure. This edition includes eXtremeDB Data Relay technology that replicates selected changes to external systems such as enterprise applications and database systems.
SQL ODBC/JDBC
The eXtremeSQL edition provides
Kernel mode deployment
The eXtremeDB Kernel Mode edition deploys the database system within an operating system kernel, to provide database functions to kernel-based applications logic.[14]
Features for managing market data
eXtremeDB Financial Edition provides features for managing
Benchmarks
McObject published reports on benchmark tests employing eXtremeDB. Main-Memory vs. RAM-Disk Databases: a Linux-Based Benchmark examined
In November, 2012 a marketing report was published for
In late 2014, two more audited benchmark reports were dedicated to eXtremeDB Financial Edition. The first, dated October 29, evaluated McObject's DBMS performance on IBM POWER8 hardware, while the second, on November 18, detailed its application in cloud computing. In 2016, an additional report was conducted to gauge the capabilities of the eXtremeDB Financial Edition.[19]
