- Cache 和 Buffer 都是缓存,主要区别是什么? - 知乎
Buffer的核心作用是用来缓冲,字面意思缓慢冲击。 比如你每秒要写100次硬盘,对系统冲击很大,浪费了大量时间忙着写处理,用个buffer缓冲区暂存起来,变成每秒要写10次硬盘,对系统冲击极大程度缓解了,因为写入效率变高了。
- terminology - What does it mean by buffer? - Stack Overflow
Here, the buffer array is used to store the data read by read (2) until it's written; then the buffer is re-used There are more complicated buffer schemes used, for example a circular buffer, where some finite number of buffers are used, one after the next; once the buffers are all full, the index "wraps around" so that the first one is re-used

- sql - How to increase dbms_output buffer? - Stack Overflow
4 When buffer size gets full There are several options you can try: 1) Increase the size of the DBMS_OUTPUT buffer to 1,000,000 2) Try filtering the data written to the buffer - possibly there is a loop that writes to DBMS_OUTPUT and you do not need this data 3) Call ENABLE at various checkpoints within your code Each call will clear the buffer
