Method Details

readAvailableGtidSet

private static io.debezium.connector.mysql.GtidSet readAvailableGtidSet(Configuration config)

waitForGtidSetsToMatch

protected static void waitForGtidSetsToMatch(Configuration master,
 Configuration replica)

Wait up to 10 seconds until the replica catches up with the master.

Parameters:

master - the configuration with the RelationalDatabaseConnectorConfig.HOSTNAME and MySqlConnectorConfig.PORT configuration properties for the MySQL master; may not be null

replica - the configuration with the RelationalDatabaseConnectorConfig.HOSTNAME and MySqlConnectorConfig.PORT configuration properties for the MySQL replica; may not be null

• waitForGtidSetsToMatch(Configuration, Configuration, long, TimeUnit)

waitForGtidSetsToMatch

protected static void waitForGtidSetsToMatch(Configuration master,
 Configuration replica,
 long timeout,
 TimeUnit unit)

Wait a maximum amount of time until the replica catches up with the master.

Parameters:

master - the configuration with the RelationalDatabaseConnectorConfig.HOSTNAME and MySqlConnectorConfig.PORT configuration properties for the MySQL master; may not be null

replica - the configuration with the RelationalDatabaseConnectorConfig.HOSTNAME and MySqlConnectorConfig.PORT configuration properties for the MySQL replica; may not be null

timeout - the maximum amount of time to wait

unit - the time unit for the timeout

See Also:

• waitForGtidSetsToMatch(Configuration, Configuration)

readSystemVariables

protected Map<String,String> readSystemVariables(Configuration config)
                                          throws Exception

Read the system variables and master status using the given connector configuration. This can be used when creating ConnectorOutputTest.TestSpecification instances with variables.

When connected to a replica, the GTID source for the master is added to the variables using the "@{code master_uuid}" variable, which does not correspond to a real MySQL system variable. The GTID source of the server to which the test case connects is given by the "server_uuid" system variable.

Parameters:

config - the connector configuration; never null

Returns:

the available system variables

Throws:

Exception - if there is a problem connecting to the database and reading the system variables

Overrides:

addValueComparatorsByFieldPath

protected void addValueComparatorsByFieldPath(BiConsumer<String,VerifyRecord.RecordValueComparator> comparatorsByPath)

Overrides:

assertSameGtidSet
