Detailed Description

An XID event is generated for a commit of a transaction that modifies one or more tables of an XA-capable storage engine.

Binary Format

The Body has the following component:

Body for Xid_event
Name	Format	Description
xid	8 byte unsigned integer	The XID transaction number.

The Post-Header and Body for this event type are empty; it only has the common header.

Constructor & Destructor Documentation

◆ Xid_event() [1/2]

binary_log::Xid_event::Xid_event ( uint64_t xid_arg )

inlineexplicit

The minimal constructor of Xid_event, it initializes the instance variable xid and set the type_code as XID_EVENT in the header object in Binary_log_event.

◆ Xid_event() [2/2]

binary_log::Xid_event::Xid_event	(	const char *	buf,
		const Format_description_event *	fde
	)

An XID event is generated for a commit of a transaction that modifies one or more tables of an XA-capable storage engine.

Parameters

buf	Contains the serialized event.
fde	An FDE event (see Rotate_event constructor for more info).
