Member Function Documentation

consumption_requested()

virtual void Log_consumer::consumption_requested ( lsn_t  request_lsn )

pure virtual

Request the log consumer to consume faster.

Remarks

This is called whenever the redo log consumer is the most lagging one and it is critical to consume up to the request_lsn. The caller has to hold log.files_mutex and log.limits_mutex.

Implemented in Arch_log_consumer, Log_user_consumer, and Log_checkpoint_consumer.

get_consumed_lsn()

virtual lsn_t Log_consumer::get_consumed_lsn ( ) const

pure virtual

Returns

Maximum LSN up to which this consumer has consumed redo. The caller should acquire log.files_mutex.

Implemented in Arch_log_consumer, Log_user_consumer, and Log_checkpoint_consumer.

get_name()

virtual const std::string & Log_consumer::get_name ( ) const

pure virtual

Returns

Name of this consumer.

Implemented in Arch_log_consumer, Log_user_consumer, and Log_checkpoint_consumer.
