A Powerful, Persistent Memory Caching Solution

The in-memory database system (IMDS) as a powerful, persistent memory caching solution.

Has the RDBMS reached its limits in today’s highly scalable Web-based applications?

While object caching (such as Memcached) and NoSQL solutions may fit some scalable, high performance systems, many high volume applications still benefit greatly from “real” database features that support persistence, recoverability, ease of programming and data design, data integrity and more.

The 64-bit in-memory database system (IMDS) combines benefits of both categories: the fastest possible Web data access, along with the reliability, recoverability and programming/design features of a proven database system.

For example, McObject’s eXtremeDB-64 is increasingly popular as a real-time caching layer for financial, Web-based social networking, SaaS and other emerging applications.

The Problem

Business and social transactions are rapidly moving to the Internet. Data sets supporting Web-based financial, commercial, e-commerce, and social networks are growing fast, but as they scale, quality of experience can vary widely between visits as popular sites buckle under the load of heavy traffic. Too often, the information needed to satisfy a user, or to close a sale, is trapped in a back-end DBMS.

Disk-based storage severely cramps data availability. Traditional object caching solutions provide speed by keeping some records in memory. But they lack means for recovery or ensuring data consistency in the event of system failure. NoSQL solutions are scalable and address specific problem domains, but they, too lack features such as ACID transactions, formal data access and definition languages, and more.

The Solution: eXtremeDB-64

The eXtremeDB-64 solution blends the highest speed and data availability with the durability, safeguards on data integrity, and sophisticated querying capabilities that are DBMS hallmarks.

Positioning eXtremeDB-64 as the front-end for a traditional database lends high volume systems the benefits of all-in-memory data access. It also ensures continuous operation and data consistency, proven in a wide variety of applications.

eXtremeDB-64 features include:

  • Transaction logging
  • A Cluster edition that multiplies net available processing power, ensures availability/uptime and enables cost-effective system expansion
  • A High Availability edition for master/slave replication with automatic failover
  • 64-bit support for very large databases, proven at 1+ terabytes, 15 billion rows and beyond
  • Pure in-memory design eliminates I/O, cache management, data transfer and other overhead, resulting in the fastest possible responsiveness
  • Progressive error-detection and other sophisticated debugging features
  • Multiple APIs: native/navigational C/C++, SQL ODBC & JDBC, Java Native Interface and native C# (.NET)
  • eXtremeDB Data Relay for efficient, fine-grained data-sharing with external systems
