    Quoted: Each index record in InnoDB contains a header of six bytes. The header is used to link consecutive records together, and also in row-level locking. Records in the clustered index contain fields for all user-defined columns. In addition, there is a six-byte field for the transaction ID and a seven-byte field for the roll pointer.
