Detailed Description

Class that aggregates important information about already certified gtid.

GTID consists of TSID and transaction number. Due to the fact that TSID is represented internally by the number relative to the used sidno map, there are as many GTID representations as maps used (snapshot map / global server map used in TC / group sid map...) Certified GTID provides information about server representation of the GTID (used globally in the TC) and group representation of the GTID (group gtid). Other information used in the code and aggregated inside of this class is: type of the certified GTID, certification result (negative/positive/negative-error) and information whether this GTID is local to the current server performing certification

Constructor & Destructor Documentation

Certified_gtid() [1/3]

gr::Certified_gtid::Certified_gtid	(	const Gtid &	server_gtid,
		const Gtid &	group_gtid,
		bool	is_gtid_specified,
		bool	is_local,
		const Certification_result &	cert_result = Certification_result::negative
	)

Constructs Certified_gtid object.

Parameters

server_gtid	GTID as seen by server (global)
group_gtid	GTID as seen by group (local to group)
is_gtid_specified	True if GTID is specified
is_local	pass true if transaction originates from this server
cert_result	Obtained certification result for transaction
