Ivan Andika updated HDDS-15684:
-------------------------------
Description:
Just an idea.
Came across
[https://medium.com/@sgn00/triple-buffer-lock-free-concurrency-primitive-611848627a1e]
We can try to think whether we can use triple buffer to replace the current
double buffer.
The current weakness of double buffer is that we cannot swap the buffers if
there is either a read or write in progress (or there might be data
corruption).
The third buffer idea will add another buffer. This would decouple the read and
writer. We can also implement the lockless implementation to improve the
performance.
