SDK writing strategies(fan-out write for example)

maybe a third strategy, chains and fan-out. Write to a primary and that server will fan-out from there.
除了扇出写，链式写之外，有没有必要再添加一个这两种混合的写模式？SDK先写主副本，然后主副本进行扇出写。

The issue discusses adding SDK write strategies, including fan-out, chained, and hybrid writes. Start by locating the SDK's existing write-strategy entry points and documenting how each current mode behaves. Done means the project has a decided scope for the hybrid mode, including whether the SDK writes the primary replica before that replica fans out.
