After this, it opens the file and returns the file descriptor to the caller, [6] with the data buffer that was passed to the function with the template now containing the new filename. [7] The file can be deleted immediately after the mkstemp call returns to prevent other processes from opening it, but the file can still be used because the ...
A victim buffer is a type of write buffer that stores dirty evicted lines in write-back caches [note 1] so that they get written back to main memory. Besides reducing pipeline stall by not waiting for dirty lines to write back as a simple write buffer does, a victim buffer may also serve as a temporary backup storage when subsequent cache ...
The write is one of the most basic routines provided by a Unix-like operating system kernel. It writes data from a buffer declared by the user to a given device, such as a file. This is the primary way to output data from a program by directly using a system call. The destination is identified by a numeric code.
A schema for a particular use of protocol buffers associates data types with field names, using integers to identify each field. (The protocol buffer data contains only the numbers, not the field names, providing some bandwidth/storage savings compared with systems that include the field names in the data.)
Copy-on-write (COW), also called implicit sharing [1] or shadowing, [2] is a resource-management technique [3] used in programming to manage shared data efficiently. Instead of copying data right away when multiple programs use it, the same data is shared between programs until one tries to modify it.
In computer science, a data buffer (or just buffer) is a region of memory used to store data temporarily while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers); however, a buffer may be used when data is moved between processes ...
Sending that file by using mmap of file data and a cycle of write calls, reduces the context switches to 2 per write call and avoids those previous 2 extra user data copies. Sending the same file via zero copy reduces the context switches to 2 per sendfile call and eliminates all CPU extra data copies (both in user and in kernel space). [1] [2 ...
Jackson (API) can read and write line-delimited JSON texts. logstash includes a json_lines codec. [10] ldjson-stream module for Node.js; ld-jsonstream dependency free module for Node.js; json-stream-es is a JavaScript/TypeScript library (frontend and backend) that can create and read newline-delimited JSON documents.
