  • Enum Constant Details

    • UNKNOWN

      public static final EventType UNKNOWN
      Events of this event type should never occur. Not written to a binary log.

    • START_V3

      public static final EventType START_V3
      A descriptor event that is written to the beginning of the each binary log file. (In MySQL 4.0 and 4.1, this event is written only to the first binary log file that the server creates after startup.) This event is used in MySQL 3.23 through 4.1 and superseded in MySQL 5.0 by FORMAT_DESCRIPTION.

    • QUERY

      public static final EventType QUERY
      Written when an updating statement is done.

    • STOP

      public static final EventType STOP
      Written when mysqld stops.

    • ROTATE

      public static final EventType ROTATE
      Written when mysqld switches to a new binary log file. This occurs when someone issues a FLUSH LOGS statement or the current binary log file becomes larger than max_binlog_size.

    • INTVAR

      public static final EventType INTVAR
      Written every time a statement uses an AUTO_INCREMENT column or the LAST_INSERT_ID() function; precedes other events for the statement. This is written only before a QUERY and is not used in case of RBR.

    • LOAD

      public static final EventType LOAD
      Used for LOAD DATA INFILE statements in MySQL 3.23.

    • SLAVE

      public static final EventType SLAVE
      Not used.

    • CREATE_FILE

      public static final EventType CREATE_FILE
      Used for LOAD DATA INFILE statements in MySQL 4.0 and 4.1.

    • APPEND_BLOCK

      public static final EventType APPEND_BLOCK
      Used for LOAD DATA INFILE statements as of MySQL 4.0.

    • EXEC_LOAD

      public static final EventType EXEC_LOAD
      Used for LOAD DATA INFILE statements in 4.0 and 4.1.

    • DELETE_FILE

      public static final EventType DELETE_FILE
      Used for LOAD DATA INFILE statements as of MySQL 4.0.

    • NEW_LOAD

      public static final EventType NEW_LOAD
      Used for LOAD DATA INFILE statements in MySQL 4.0 and 4.1.

    • RAND

      public static final EventType RAND
      Written every time a statement uses the RAND() function; precedes other events for the statement. Indicates the seed values to use for generating a random number with RAND() in the next statement. This is written only before a QUERY and is not used in case of RBR.

    • USER_VAR

      public static final EventType USER_VAR
      Written every time a statement uses a user variable; precedes other events for the statement. Indicates the value to use for the user variable in the next statement. This is written only before a QUERY and is not used in case of RBR.

    • FORMAT_DESCRIPTION

      public static final EventType FORMAT_DESCRIPTION
      A descriptor event that is written to the beginning of the each binary log file. This event is used as of MySQL 5.0; it supersedes START_V3.

    • XID

      public static final EventType XID
      Generated for a commit of a transaction that modifies one or more tables of an XA-capable storage engine. Normal transactions are implemented by sending a QUERY containing a BEGIN statement and a QUERY containing a COMMIT statement (or a ROLLBACK statement if the transaction is rolled back).

    • BEGIN_LOAD_QUERY

      public static final EventType BEGIN_LOAD_QUERY
      Used for LOAD DATA INFILE statements as of MySQL 5.0.

    • EXECUTE_LOAD_QUERY

      public static final EventType EXECUTE_LOAD_QUERY
      Used for LOAD DATA INFILE statements as of MySQL 5.0.

    • TABLE_MAP

      public static final EventType TABLE_MAP
      This event precedes each row operation event. It maps a table definition to a number, where the table definition consists of database and table names and column definitions. The purpose of this event is to enable replication when a table has different definitions on the master and slave. Row operation events that belong to the same transaction may be grouped into sequences, in which case each such sequence of events begins with a sequence of TABLE_MAP events: one per table used by events in the sequence. Used in case of RBR.

    • PRE_GA_WRITE_ROWS

      public static final EventType PRE_GA_WRITE_ROWS
      Describes inserted rows (within a single table). Used in case of RBR (5.1.0 - 5.1.15).

    • PRE_GA_UPDATE_ROWS

      public static final EventType PRE_GA_UPDATE_ROWS
      Describes updated rows (within a single table). Used in case of RBR (5.1.0 - 5.1.15).

    • PRE_GA_DELETE_ROWS

      public static final EventType PRE_GA_DELETE_ROWS
      Describes deleted rows (within a single table). Used in case of RBR (5.1.0 - 5.1.15).

    • WRITE_ROWS

      public static final EventType WRITE_ROWS
      Describes inserted rows (within a single table). Used in case of RBR (5.1.16 - mysql-trunk).

    • UPDATE_ROWS

      public static final EventType UPDATE_ROWS
      Describes updated rows (within a single table). Used in case of RBR (5.1.16 - mysql-trunk).

    • DELETE_ROWS

      public static final EventType DELETE_ROWS
      Describes deleted rows (within a single table). Used in case of RBR (5.1.16 - mysql-trunk).

    • INCIDENT

      public static final EventType INCIDENT
      Used to log an out of the ordinary event that occurred on the master. It notifies the slave that something happened on the master that might cause data to be in an inconsistent state.

    • HEARTBEAT

      public static final EventType HEARTBEAT
      Sent by a master to a slave to let the slave know that the master is still alive. Not written to a binary log.

    • IGNORABLE

      public static final EventType IGNORABLE
      In some situations, it is necessary to send over ignorable data to the slave: data that a slave can handle in case there is code for handling it, but which can be ignored if it is not recognized.

    • ROWS_QUERY

      public static final EventType ROWS_QUERY
      Introduced to record the original query for rows events in RBR.

    • EXT_WRITE_ROWS

      Extension of UPDATE_ROWS_EVENT, allowing partial values according to binlog_row_value_options.
