# Features **1. Broad compatibility** * Java profile compact1 * No use of Unsafe, Java 9 module compatibility **2. Simple concurrency model** * Quickly write correct code with actors * Easily leverage hundreds or more cores * All pipes are defined as produced from one actor and consumed by one other **3. Separation of design concerns** * Business aware scheduling * Actors who do not have work are not scheduled * Schedulers can be custom designed or existing solutions applied * Strong types generated externally * Types between actors are externally defined * New fields can be added and mapped to new business specific usages **4. Multiple APIs** * Embedded friendly use of wrapping arrays * Integrate with a wide variety of existing interfaces * Visitors for reading and writing * Object proxies for reading and writing * Zero copy direct access to input and output fields * Replay of messages until they are released **5. Simple debug and refactoring** * Messages have full provenance and actor chain upon exception * Test framework supports automated regression test construction for refactor * Fuzz testing based on message pipes definitions * Generative contract testing based on behavior definitions for stages **6. Static memory allocations** * No need to release memory and no GC * Simplify memory usage analysis of the application * Minimize runtime failures, including out of memory **7. Copy preferred over lock usage** * No stalled cores, block free, wait free, continuous progress * Efficient power usage * Leverages new fast memory subsystems * Enables efficient NUMA usage **8. Sequential memory usage** * Leverages CPU pre-fetch and caches for fastest possible throughput * Persistence and immediate start up for free with non-volatile memory * All media is sequential, mechanical sympathy * Maximum use of hardware bandwidth **9. Software sketches** * Extensive requirements gathering put into a graph * Involve non-technical people in the early stages * Refine the design before making any commitments, or beginning iterations **10. Minimized deployed application** * For embedded systems, only the needed applications and interfaces are deployed * Configuration is done at compile time * Ultra-small attack surface * Scales well in docker and cloud deployments * Targets absolute minimum resources consumed --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://oci-pronghorn.gitbook.io/pronghorn/chapter-0-what-is-pronghorn/features.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
