The related system call fsync() commits just the buffered data relating to a specified file descriptor. [1] fdatasync() is also available to write out just the changes made to the data in the file, and not necessarily the file's related metadata. [2] Some Unix systems run a kind of flush or update daemon, which calls the sync function on a ...
To avoid this, a temporary per-subvolume log tree is created to journal fsync-triggered copies on write. Log trees are self-contained, tracking their own extents and keeping their own checksum items. Their items are replayed and deleted at the next full tree commit or (if there was a system crash) at the next remount.
Sync, a signal used in composite video systems to coordinate the timings of lines, fields and frames; DIN sync, a standard interface for electronic music instruments; Ford Sync, an in-car communications and entertainment system; Oscillator sync, where a slave oscillator is reset by a master oscillator
The Mai Zheng et al. paper claims to point out failures in LMDB, but the conclusion depends on whether fsync or fdatasync is utilised. Using fsync ameliorates the problem. The selection of fsync over fdatasync is a compile-time switch that is not the default behavior in current Linux builds of LMDB but is the default on macOS, *BSD, Android ...
8 to 12 bits parallel data line These are parallel data lines that carry pixel data. The data transmitted on these lines change with every Pixel Clock (PCLK). Horizontal Sync (HSYNC) This is a special signal that goes from the camera sensor or ISP to the camera interface. An HSYNC indicates that one line of the frame is transmitted.
Using this method, the receiver detects the 'first' edge transition... (the START bit), waits 'half a bit duration' and then reads the value of the signal. A further delay of one 'whole bit duration' is executed before the next data bit is 'read' - repeating for the length of the whole serial word (typically 7/8-data bits).

Considering the hardware limitations regarding preservation of data in the event of sudden power loss and the ineffectiveness of approaches commonly employed by developers to prevent these sorts of losses, many database engines do not by default call FileDescriptor.sync() nor FileChannel.force() nor fsync or equivalents for every commit because ...
