Member Function Documentation

virtual ReplicationReturnCode drizzled::plugin::TransactionApplier::apply ( Session &  in_session,
const message::Transaction &  to_apply 
)
pure virtual

Apply something to a target.

Note:

It is important to note that memory allocation for the supplied pointer is not guaranteed after the completion of this function – meaning the caller can dispose of the supplied message. Therefore, appliers which are implementing an asynchronous replication system must copy the supplied message to their own controlled memory storage area.

Parameters:
Transactionmessage to be replicated

Implemented in drizzle_plugin::RabbitMQLog, drizzle_plugin::ZeroMQLog, and ReplicationLog.
