Class RowMapper

java.lang.Object

io.debezium.connector.oracle.logminer.RowMapper

public class RowMapper
extends Object

A utility class to map LogMiner content resultSet values. This class gracefully logs errors, loosing an entry is not critical. The loss will be logged

                                  ResultSet rs)

getSegOwner

public static String getSegOwner(OracleStreamingChangeEventSourceMetrics streamingMetrics,
                                 ResultSet rs)

getChangeTime

public static Timestamp getChangeTime(OracleStreamingChangeEventSourceMetrics streamingMetrics,
                                      ResultSet rs)

getScn

public static Scn getScn(OracleStreamingChangeEventSourceMetrics streamingMetrics,
                         ResultSet rs)

getTransactionId

public static String getTransactionId(OracleStreamingChangeEventSourceMetrics streamingMetrics,
                                      ResultSet rs)

getSqlRedo

public static String getSqlRedo(OracleStreamingChangeEventSourceMetrics streaingMetrics,
                                ResultSet rs,
                                boolean isDml,
                                HistoryRecorder historyRecorder,
                                Scn scn,
                                String tableName,
                                String segOwner,

                                String txId)

It constructs REDO_SQL. If REDO_SQL is in a few lines, it truncates after first 40_000 characters It also records LogMiner history info if isDml is true

Parameters:

streaingMetrics - the streaming metrics

rs - result set

isDml - flag indicating if operation code is a DML

historyRecorder - history recorder

scn - scn

tableName - table name

segOwner - segment owner

operationCode - operation code

changeTime - time of change

txId - transaction ID

Returns:

the redo SQL

getTableId

public static TableId getTableId(String catalogName,
                                 ResultSet rs)
