Dear Wang,
> Some codes were added in ReorderBufferProcessTXN() for treating DDL,
My mailer went wrong, so I'll put comments again. Sorry.
Some codes were added in ReorderBufferProcessTXN() for treating DDL,
but I doubted updating accept_writes is needed.
IMU, the parameter is read by OutputPluginPrepareWrite() in order align messages.
They should have a header - like 'w' - before their body. But here only a keepalive message is sent,
no meaningful changes, so I think it might be not needed.
I commented out the line and tested like you did [1], and no timeout and errors were found.
Do you have any reasons for that?
Best Regards,
Hayato Kuroda
