Description of the illustration xla

This figure focuses on the same update record, within the same series of transaction log records, as in the previous figure (also refer to that description). This time, however, the update record is depicted with a single Tuple row that is expanded to show there is fixed-length data and variable-length data. An arrow pointing from the fixed-length data to the variable-length data indicates an address used to locate variable-length data. Column offsets are shown to be ttXlaColDesc_t ->offset + rowAddress, with four arrows pointing to various positions within the fixed-length data.

End of description.
