How radonDB implement Snapshot Isolation #7
Comments
Hi @louishust, radon has a commit lock to make snapshot isolation: Line 573 in a81a767
2, At the same time, if a read query executing, it will try to acquire the same lock at: Line 363 in a81a767
So, he must wait the committing done. This is the key to support snapshot isolation. |
Thanks for your reply. So the performance is like one thread? If deploy two radondb in one cluster, how to maintain the lock? |
1, As the case we talked above,, its YES. |
Is there some design doc for implementation of Snapshot Isolation ?
Queue commit action?
