Configuration holds replication configuration information gathered from performance_schema and global variables.

Used in: FullStatus

• double heartbeat_interval = 1

  HeartbeatInterval controls the heartbeat interval that the primary sends to the replica

• int32 replica_net_timeout = 2

  ReplicaNetTimeout specifies the number of seconds to wait for more data or a heartbeat signal from the source before the replica considers the connection broken

FullStatus contains the full status of MySQL including the replication information, semi-sync information, GTID information among others

PrimaryStatus is the replication status for a MySQL primary (returned by 'show binary log status').

Used in: FullStatus, tabletmanagerdata.DemotePrimaryResponse, tabletmanagerdata.PrimaryStatusResponse

• string position = 1

• string file_position = 2

• string server_uuid = 3

Status is the replication status for MySQL/MariaDB/File-based. Returned by a flavor-specific command and parsed into a Position and fields.

Used in: FullStatus, StopReplicationStatus, tabletmanagerdata.ReplicationStatusResponse, vtctldata.ShardReplicationPositionsResponse

• string position = 1

• uint32 replication_lag_seconds = 4

• string source_host = 5

• int32 source_port = 6

• int32 connect_retry = 7

• string relay_log_position = 8

  RelayLogPosition will be empty for flavors that do not support returning the full GTIDSet from the relay log, such as MariaDB.

• string file_position = 9

• string relay_log_source_binlog_equivalent_position = 10

• uint32 source_server_id = 11

• string source_uuid = 12

StopReplicationMode is used to provide controls over how replication is stopped.

Used in: tabletmanagerdata.StopReplicationAndGetStatusRequest

• IOANDSQLTHREAD = 0

• IOTHREADONLY = 1

StopReplicationStatus represents the replication status before calling StopReplication, and the replication status collected immediately after calling StopReplication.

Used in: tabletmanagerdata.StopReplicationAndGetStatusResponse

• optional Status before = 1

• optional Status after = 2
