◆ consumption_requested()

void Arch_log_consumer::consumption_requested ( lsn_t  request_lsn)
overridevirtual

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.

Implements Log_consumer.

◆ get_consumed_lsn()

lsn_t Arch_log_consumer::get_consumed_lsn ( ) const
overridevirtual
Returns
Maximum LSN up to which this consumer has consumed redo. The caller should acquire log.files_mutex.

◆ get_name()

const std::string & Arch_log_consumer::get_name ( ) const
