所以HashingWriteBuffer 总是使用着下一层(儿子)的 working_buffer。 HashingWriteBuffer也继承 BufferWithOwnMemory ,那他也有自己的内存区域,它不像 CompressedWriteBuffer 和 WriteBufferFromFileBase 一样,使用初始化时申请的 OwnMemory 作为自己的working_buffer。 HashingWriteBuffer 的 OwnMemory 作用是 calculateHash...

参考手册: The doublewrite buffer is a storage area whereInnoDBwrites pages flushed from the buffer pool before writing the pages to their proper positions in theInnoDBdata files. If there is an operating system, storage subsystem, or unexpectedmysqldprocess exit in the middle of a page write,...
The AMD LogiCORE™ IP Video Frame Buffer Read and Video Frame Buffer Write cores provide high-bandwidth direct memory access between memory and AXI4-Stream video type target peripherals, which support the AXI4-Stream Video protocol.

For a wide-oriented binary stream, the position will be backed up based on the number of bytes used to represent the wide char in the ungetc buffer. For this reason, attempting to use ungetwc() on a character when the destination is a binary wide-oriented stream that was never read in...

Write buffer cycle: refers to the "buffer time window N" mentioned above, which represents the delay that data users can accept when synchronizing data from Tcapdb to a third-party system. The higher this value is, the less sensitive the user is to the delay. The Tcapdb side will de-du...
