getTableNameCaseSensitivity

public StreamingAdapter.TableNameCaseSensitivity getTableNameCaseSensitivity(OracleConnection connection)

Description copied from interface: StreamingAdapter

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

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

Description copied from interface: StreamingAdapter

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
