Method Details

getType

String getType()

getHistoryRecordComparator

HistoryRecordComparator getHistoryRecordComparator()

getOffsetContextLoader

OffsetContext.Loader<OracleOffsetContext> getOffsetContextLoader()

getSource

StreamingChangeEventSource<OraclePartition,OracleOffsetContext> getSource(OracleConnection connection,
 EventDispatcher<OraclePartition,TableId> dispatcher,
 ErrorHandler errorHandler,
 Clock clock,
 OracleDatabaseSchema schema,
 OracleTaskContext taskContext,
 Configuration jdbcConfig,
 OracleStreamingChangeEventSourceMetrics streamingMetrics)

getTableNameCaseSensitivity

default StreamingAdapter.TableNameCaseSensitivity getTableNameCaseSensitivity(OracleConnection connection)

Returns whether table names are case sensitive. By default the Oracle driver returns table names that are case sensitive. The table names will be returned in upper-case by default and will only be returned in lower or mixed case when the table is created using double-quotes to preserve case. The adapter aligns with the driver's behavior and enforces that table names are case sensitive by default.

Parameters:

connection - database connection, should never be null

Returns:

the case sensitivity setting for table names used by the connector's runtime adapter

determineSnapshotOffset

OracleOffsetContext determineSnapshotOffset(RelationalSnapshotChangeEventSource.RelationalSnapshotContext<OraclePartition,OracleOffsetContext> ctx,
 OracleConnectorConfig connectorConfig,
 OracleConnection connection)
                                     throws SQLException

Returns the offset context based on the snapshot state.

Parameters:

ctx - the relational snapshot context, should never be null

connectorConfig - the connector configuration, should never be null

connection - the database connection, should never be null

Returns:

the offset context, never null

Throws:

SQLException - if a database error occurred

getValueConverter

default OracleValueConverters getValueConverter(OracleConnectorConfig connectorConfig,
 OracleConnection connection)

Returns the value converter for the streaming adapter.

Parameters:

connectorConfig - the connector configuration, shoudl never be null

connection - the database connection, should never be null

Returns:

the value converter to be used
