ibd2sdi Options

--help, -h

Displays command-line help.

shell> ibd2sdi --help
Usage: ./ibd2sdi [-v] [-c <strict-check>] [-d <dump file name>] [-n] filename1 [filenames]
See http://dev.mysql.com/ibd2sdi.html for usage hints.
  -h, --help          Display this help and exit.
  -v, --version       Display version information and exit.
  -#, --debug[=name]  Output debug log. See
                      http://dev.mysql.com/dbug-package.html
  -d, --dump-file=name 
                      Dump the tablespace SDI into the file passed by user.
                      Without the filename, it will default to stdout
  -s, --skip-data     Skip retrieving data from SDI records. Retrieve only id
                      and type.
  -i, --id=#          Retrieve the SDI record matching the id passed by user.
  -t, --type=#        Retrieve the SDI records matching the type passed by
                      user.
  -c, --strict-check=name 
                      Specify the strict checksum algorithm by the user.
                      Allowed values are innodb, crc32, none.
  -n, --no-check      Ignore the checksum verification.
  -p, --pretty        Pretty format the SDI output.If false, SDI would be not
                      human readable but it will be of less size
                      (Defaults to on; use --skip-pretty to disable.)

--version, -v

Displays MySQL version information.

shell> ibd2sdi --version
ibd2sdi  Ver 8.0.3-dmr for Linux on x86_64 (Source distribution)

--debug[=debug_options], -# [debug_options]

Prints a debug log. For debug options, refer to Section 29.5.4, “The DBUG Package”.

shell> ibd2sdi --debug=d:t /tmp/ibd2sdi.trace

--dump-file=, -d

Dumps serialized dictionary information (SDI) into the specified dump file. If a dump file is not specified, the tablespace SDI is dumped to stdout.

shell> ibd2sdi --dump-file=file_name ../data/test/t1.ibd

--skip-data, -s

Skips retrieval of data field values from the serialized dictionary information (SDI) and only retrieves the id and type field values, which are primary keys for SDI records.

shell> ibd2sdi --skip-data ../data/test/t1.ibd
["ibd2sdi"
,
{
	"type": 1,
	"id": 330
}
,
{
	"type": 2,
	"id": 7
}
]

--id=#, -i #

Retrieves serialized dictionary information (SDI) matching the specified table or tablespace object id. An object id is unique to the object type. Table and tablespace object IDs are also found in the id column of the mysql.tables and mysql.tablespace data dictionary tables. For information about data dictionary tables, see Section 14.1, “Data Dictionary Schema”.

shell> ibd2sdi --id=7 ../data/test/t1.ibd

	"type": 2,
	"id": 7,

            }
        ]
    }
}
}
]

--type=#, -t #

Retrieves serialized dictionary information (SDI) matching the specified object type. SDI is provided for table (type=1) and tablespace (type=2) objects.

shell> ibd2sdi --type=2 ../data/test/t1.ibd
["ibd2sdi"

{
	"type": 2,

            }
        ]
    }
}
}

--strict-check, -c

Specifies a strict checksum algorithm for validating the checksum of pages that are read. Options include innodb, crc32, and none.

In this example, the strict version of the innodb checksum algorithm is specified:

shell> ibd2sdi --strict-check=innodb ../data/test/t1.ibd

In this example, the strict version of crc32 checksum algorithm is specified:

shell> ibd2sdi -c crc32 ../data/test/t1.ibd

If you do not specify the --strict-check option, validation is performed against non-strict innodb, crc32 and none checksums.

--no-check, -n

Skips checksum validation for pages that are read.

shell> ibd2sdi --no-check ../data/test/t1.ibd

--pretty, -p

Outputs SDI data in JSON pretty print format. Enabled by default. If disabled, SDI is not human readable but is smaller in size. Use --skip-pretty to disable.

shell> ibd2sdi --skip-pretty ../data/test/t1.ibd
