SymmetricDS 中源节点宕机会发生什么?
如果“源”节点已关闭且“目标”节点已启动,则“目标”节点是否可以充当 SymmetricDS for PostgreSQL 中的“源”节点
If the 'Source' node gets down and the 'Target' nodes are up, can the 'Target' node does act as a 'Source' node in SymmetricDS for PostgreSQL

如果数据从 A(源)单向同步到 B(目标),则如果源已关闭,即 A 则 B 需要等待 A 重新上线
如果数据是双向同步,例如 A 和 B 都是源,并且都是 A目标,或者,如果 A 从 A(B 的源)到 B(A 的目标)以及从 B(C 的源、A 的目标)到 C(B 的目标)单向同步,则如果 A 已关闭,B 可以继续发挥源头的作用对于 A 或 C
If data is synced unidirectionally from A (source) to B (target) then if the source is down, i.e. A then B needs to wait until A got back online
If data is synced bidirectionally such as both A and B are a source and a target, or, if A is synced unidirectionally from A (source of B) to B (target of A) and from B (source of C, target of A) to C (target of B) then if A is down B can continue working in its role of source either for A or for C
