DESCRIPTION:
Store in binlog (and show in mysqlbinlog output) texts of statements that
caused RBR events
This is needed for (list from Monty):
- Easier to understand why updates happened
- Would make it easier to find out where in application things went
wrong (as you can search for exact strings)
- Allow one to filter things based on comments in the statement.
The cost of this can be that the binlog will be approximately 2x in size
(especially insert of big blob's would be a bit painful), so this should
be an optional feature.

First suggestion:
> I think for this we would actually need a new binlog event type

New server option
~~~~~~~~~~~~~~~~~
--binlog-annotate-row-events
Setting this option makes RBR (row-) events in the binary log to be
preceded by Annotate rows events (see below). The corresponding
'binlog_annotate_row_events' system variable is dynamic and has both
global and session values. Default global value is OFF.
Note. Session values are usefull to make it possible to annotate only
some selected statements:
...
SET SESSION binlog_annotate_row_events=ON;
... statements to be annotated ...
SET SESSION binlog_annotate_row_events=OFF;
... statements not to be annotated ...
New binlog event type
~~~~~~~~~~~~~~~~~~~~~
Annotate_rows_log_event [ ANNOTATE_ROWS_EVENT ]
Describes the query which caused the corresponding row event. In binary log,
precedes each Table_map_log_event. Contains empty post-header and the query
text in its data part.
The numeric code for this event must be assigned carefully. It should be
coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL
uses the same numeric code for one event that MariaDB uses for
ANNOTATE_ROWS_EVENT, which would make merging the two impossible.

DESCRIPTION:
Store in binlog (and show in mysqlbinlog output) texts of statements that
caused RBR events
This is needed for (list from Monty):
- Easier to understand why updates happened
- Would make it easier to find out where in application things went
wrong (as you can search for exact strings)
- Allow one to filter things based on comments in the statement.
The cost of this can be that the binlog will be approximately 2x in size
(especially insert of big blob's would be a bit painful), so this should
be an optional feature.

New binlog event type
~~~~~~~~~~~~~~~~~~~~~
Annotate_rows_log_event [ ANNOTATE_ROWS_EVENT ]
Describes the query which caused the corresponding row event. In binary log,
precedes each Table_map_log_event. Contains empty post-header and the query
text in its data part.
The numeric code for this event must be assigned carefully. It should be
coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL
uses the same numeric code for one event that MariaDB uses for
ANNOTATE_ROWS_EVENT, which would make merging the two impossible.

DESCRIPTION:
Store in binlog (and show in mysqlbinlog output) texts of statements that
caused RBR events
This is needed for (list from Monty):
- Easier to understand why updates happened
- Would make it easier to find out where in application things went
wrong (as you can search for exact strings)
- Allow one to filter things based on comments in the statement.
The cost of this can be that the binlog will be approximately 2x in size
(especially insert of big blob's would be a bit painful), so this should
be an optional feature.

> I think for this we would actually need a new binlog event type
> (Comment_log_event?). Unless we want to log an empty statement Query_log_event
> containing only a comment (a bit of a hack).
New server option
~~~~~~~~~~~~~~~~~
--binlog-annotate-row-events
Setting this option makes RBR (row-) events in the binary log to be
preceded by Annotate rows events (see below). The corresponding
'binlog_annotate_row_events' system variable is dynamic and has both
global and session values. Default global value is OFF.
Note. Session values are usefull to make it possible to annotate only
some selected statements:
...
SET SESSION binlog_annotate_row_events=ON;
... statements to be annotated ...
SET SESSION binlog_annotate_row_events=OFF;
... statements not to be annotated ...
New binlog event type
~~~~~~~~~~~~~~~~~~~~~
Annotate_rows_log_event [ ANNOTATE_ROWS_EVENT ]
Describes the query which caused the corresponding row event. In binary log,
precedes each Table_map_log_event. Contains empty post-header and the query
text in its data part. Example:

DESCRIPTION:
Store in binlog (and show in mysqlbinlog output) texts of statements that
caused RBR events
This is needed for (list from Monty):
- Easier to understand why updates happened
- Would make it easier to find out where in application things went
wrong (as you can search for exact strings)
- Allow one to filter things based on comments in the statement.
The cost of this can be that the binlog will be approximately 2x in size
(especially insert of big blob's would be a bit painful), so this should
be an optional feature.

New server option
~~~~~~~~~~~~~~~~~
--binlog-annotate-row-events
Setting this option makes RBR (row-) events in the binary log to be
preceded by Annotate rows events (see below). The corresponding
'binlog_annotate_row_events' system variable is dynamic and has both
global and session values. Default global value is OFF.
Note. Session values are usefull to make it possible to annotate only
some selected statements:
...
SET SESSION binlog_annotate_row_events=ON;
... statements to be annotated ...
SET SESSION binlog_annotate_row_events=OFF;
... statements not to be annotated ...
New binlog event type
~~~~~~~~~~~~~~~~~~~~~
Annotate_rows_log_event [ ANNOTATE_ROWS_EVENT ]
Describes the query which caused the corresponding row event. In binary log,
precedes each Table_map_log_event. Contains empty post-header and the query
text in its data part. Example:
...

DESCRIPTION:
Store in binlog (and show in mysqlbinlog output) texts of statements that
caused RBR events
This is needed for (list from Monty):
- Easier to understand why updates happened
- Would make it easier to find out where in application things went
wrong (as you can search for exact strings)
- Allow one to filter things based on comments in the statement.
The cost of this can be that the binlog will be approximately 2x in size
(especially insert of big blob's would be a bit painful), so this should
be an optional feature.

New server option
~~~~~~~~~~~~~~~~~
--binlog-annotate-row-events
Setting this option makes RBR (row-) events in the binary log to be
preceded by Annotate rows events (see below). The corresponding
'binlog_annotate_row_events' system variable is dynamic and has both
global and session values. Default global value is OFF.
Note. Session values are usefull to make it possible to annotate only
some selected statements:
...
SET SESSION binlog_annotate_row_events=ON;
... statements to be annotated ...
SET SESSION binlog_annotate_row_events=OFF;
... statements not to be annotated ...
New binlog event type
~~~~~~~~~~~~~~~~~~~~~
Annotate_rows_log_event [ ANNOTATE_ROWS_EVENT ]
Describes the query which caused the corresponding row event. In binary log,
precedes each Table_map_log_event. Contains empty post-header and the query
text in its data part. Example:
...
