See the following code: ``` Configuration config = context.getFactoryConfiguration(); Map<String, String> configMap = config.toMap(); OptionUtils.printOptions(IDENTIFIER, configMap); OceanBaseConnectorOptions connectorOptions = new OceanBaseConnectorOptions(configMap); String zoneStr = context.getPipelineConfiguration().get(PIPELINE_LOCAL_TIME_ZONE); ZoneId zoneId = PIPELINE_LOCAL_TIME_ZONE.defaultValue().equals(zoneStr) ? ZoneId.systemDefault() : ZoneId.of(zoneStr); return new OceanBaseDataSink(connectorOptions, zoneId); ``` - I removed direct-load related options because the direct-load feature has been removed from flink-sql-connector-oceanbase since version 1.4. ########## flink-cdc-connect/flink-cdc-pipeline-connectors/flink-cdc-pipeline-connector-oceanbase/src/main/java/org/apache/flink/cdc/connectors/oceanbase/sink/OceanBaseMetadataApplier.java: ########## @@ -0,0 +1,142 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.
