InterSystems Cache®, a high-performance database, powers transaction processing applications all over the globe. It's used for everything, from mapping a million stars in the Milky Way to processing a trillion equity trades per day to managing smart energy grids. InterSystems has developed Cache, a multi-model (object-relational, key-value), DBMS and application server. InterSystems Cache offers multiple APIs that allow you to work with the same data simultaneously: key/value, relational/object, document, multidimensional, object, object, and object. Data can be managed using SQL, Java, node.js.NET, C++ and Python. Cache also offers an application server that hosts web apps (CSP, REST, SOAP and other types TCP access for Cache data).

Consider it a temporary memory solution for your applications. Memcached enables you to reallocate memory from areas of your system that have an excess to those that are experiencing a shortfall. While the initial example shows a traditional deployment approach, it is inefficient because the total cache size only represents a small portion of your web farm's true capacity, and maintaining cache consistency across numerous nodes requires significant effort. With memcached, all servers draw from a unified virtual memory pool, simplifying operations. Furthermore, as your application's demand increases, necessitating the addition of more servers, there is typically a corresponding rise in the volume of frequently accessed data. A deployment strategy that allows these two components of your system to scale in tandem is a more logical and efficient approach. This synergy not only optimizes resource use but also enhances overall system performance.

Bolt is a key/value store written entirely in Go, drawing inspiration from Howard Chu's LMDB project. The primary aim of this initiative is to offer a straightforward, quick, and dependable database solution for smaller projects that do not need the complexity of a full-fledged database server like Postgres or MySQL. Given that Bolt serves as a foundational component, a focus on simplicity is paramount. The API is intentionally minimal, emphasizing only the essential operations of retrieving and storing values. This streamlined approach was central to Bolt's original vision: to create an uncomplicated pure Go key/value store without overwhelming it with unnecessary features. Consequently, the project has successfully achieved this goal. Nonetheless, the narrowly defined scope has led to the conclusion of the project's development. Managing an open source database is a labor-intensive endeavor that demands significant time and resources. Any modifications to the codebase can have unforeseen and potentially severe consequences, making even minor adjustments necessitate extensive testing and validation over prolonged periods. Additionally, the project's limited functionality allows users to focus on core database operations without the distractions of a more complex system.

An adaptable and efficient key-value storage engine, both persistent and in-memory, is engineered for superior performance and resource optimization. It is crafted to effectively handle data on-disk and in-memory by identifying recurring patterns in serialized bytes, without limiting itself to any particular data model, be it SQL or NoSQL, or storage medium, whether it be Disk or RAM. The core system offers a variety of configurations that can be fine-tuned for specific use cases, while also aiming to incorporate automatic runtime adjustments by gathering and analyzing machine statistics and read-write behaviors. Users can manage data easily by utilizing well-known structures such as Map, Set, Queue, SetMap, and MultiMap, all of which can seamlessly convert to native collections in Java and Scala. Furthermore, it allows for conditional updates and data modifications using any Java, Scala, or native JVM code, eliminating the need for a query language and ensuring flexibility in data handling. This design not only promotes efficiency but also encourages the adoption of custom solutions tailored to unique application needs.
