Replication Protocol
The MariaDB replication protocol governs the replication of data from a master server to downstream slave servers.
-
1-Binlog Events
Information about data modification made to a server instance written into the binary log. -
2-Binlog Event Header
All binlog events stored in a binary log file have a common structure. -
3-Binlog Network Stream
Events stored in the binlog can be sent over the network to replicate data ... -
4-Semi-Sync Replication
After the status byte of a binlog network stream, 2 bytes are added before ... -
5-Slave Registration
COM_QUERY packets are exchanged before sending COMREGISTER_SLAVE and COM_BINLOG_DUMP. -
ANNOTATE_ROWS_EVENT
Accompany row events and describe the query which caused the row event. -
BEGIN_LOAD_QUERY_EVENT
This event is written into the binary log file for LOAD DATA INFILE events ... -
BINLOG_CHECKPOINT_EVENT
Specifies a binlog file such that XA crash recovery can start from that file. -
COM_BINLOG_DUMP
Command the slave sends to the master after COM_REGISTER_SLAVE. -
COM_REGISTER_SLAVE
Sent by the slave in order to start MariaDB replication. -
EXECUTE_LOAD_QUERY_EVENT
This event is written into the binary log file for LOAD DATA INFILE events.... -
Fake GTID_LIST event
This event is sent by master server to the registering slave. -
Fake ROTATE_EVENT
When a slave connects to a master, the first binlog event sent is Fake ROTATE_EVENT. -
FORMAT_DESCRIPTION_EVENT
Occurs at the beginning of a binary log file at position 4, after the magic number bytes. -
GTID_EVENT
For global transaction ID instead of the old BEGIN query event. -
GTID_LIST_EVENT
Logged in every binlog to record the current replication state. -
HEARTBEAT_LOG_EVENT
Sent by a master to a slave to let it know that the master is still alive. -
INTVAR_EVENT
A INTVAR_EVENT is written every time a statement uses an auto increment col... -
QUERY_EVENT
Written into the binary log file for statement-based replication, DDLs, non... -
RAND_EVENT
Contains two seed values that set the rand_seed1 and rand_seed2 system variables. -
ROTATE_EVENT
When a binary log file exceeds the size limit, a ROTATE_EVENT is written at the end of the file. -
ROWS_EVENT_V1/V2, ROWS_COMPRESSED_EVENT_V1
A ROWS_EVENT_V1 is written for row based replication if data is inserted, d... -
START_ENCRYPTION_EVENT
This event is written to every binary log file if 'encrypt_binlog' is set to ON -
STOP_EVENT
Written to the binary log when it shuts down or when resuming after a mysqld process crash. -
TABLE_MAP_EVENT
Precedes each row operation event and maps a table definition to a number. -
USER_VAR_EVENT
A USER_VAR_EVENT is written every time a statement uses a user defined vari... -
XA_PREPARE_LOG_EVENT
A XA_PREPARE_LOG_EVENT records the prepare phase of a distributed transacti... -
