Member Function Documentation

consumption_requested()

void Log_user_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 Log_user_consumer::get_consumed_lsn ( ) const

overridevirtual

Returns

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

Implements Log_consumer.

get_name()

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

overridevirtual

Returns

Name of this consumer.

Implements Log_consumer.

set_consumed_lsn()

void Log_user_consumer::set_consumed_lsn

(

lsn_t

consumed_lsn

)

Set the lsn reported by get_consumed_lsn() to the given value.

It is required that the given value is greater or equal to the value currently reported by the get_consumed_lsn().

Parameters

[in]

consumed_lsn

the given lsn to report

Member Data Documentation

m_consumed_lsn

lsn_t Log_user_consumer::m_consumed_lsn {}

private

Value reported by get_consumed_lsn().

Set by set_consumed_lsn(lsn).

m_name

const std::string Log_user_consumer::m_name

private

Name of this consumer (saved value from ctor).
