Memory Mapped Files vs Traditional File I/O
Developers should use Memory Mapped Files for high-performance scenarios involving large files, such as database systems, video processing, or scientific computing, where low-latency random access is critical meets developers should learn traditional file i/o when building applications that require direct file manipulation, such as data processing tools, batch scripts, or systems that need to read/write custom file formats. Here's our take.
Memory Mapped Files
Developers should use Memory Mapped Files for high-performance scenarios involving large files, such as database systems, video processing, or scientific computing, where low-latency random access is critical
Memory Mapped Files
Nice PickDevelopers should use Memory Mapped Files for high-performance scenarios involving large files, such as database systems, video processing, or scientific computing, where low-latency random access is critical
Pros
- +It's also valuable for inter-process communication (IPC) by allowing multiple processes to share data efficiently without copying, and in embedded systems or real-time applications where direct memory access optimizes resource usage
- +Related to: virtual-memory, inter-process-communication
Cons
- -Specific tradeoffs depend on your use case
Traditional File I/O
Developers should learn Traditional File I/O when building applications that require direct file manipulation, such as data processing tools, batch scripts, or systems that need to read/write custom file formats
Pros
- +It is crucial for scenarios where high-level abstractions like databases are unnecessary, such as simple configuration storage, log file generation, or interfacing with legacy file-based systems
- +Related to: streams, buffered-io
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Memory Mapped Files if: You want it's also valuable for inter-process communication (ipc) by allowing multiple processes to share data efficiently without copying, and in embedded systems or real-time applications where direct memory access optimizes resource usage and can live with specific tradeoffs depend on your use case.
Use Traditional File I/O if: You prioritize it is crucial for scenarios where high-level abstractions like databases are unnecessary, such as simple configuration storage, log file generation, or interfacing with legacy file-based systems over what Memory Mapped Files offers.
Developers should use Memory Mapped Files for high-performance scenarios involving large files, such as database systems, video processing, or scientific computing, where low-latency random access is critical
