|ID||(Required) The ID attribute is a pervasive attribute that uniquely identifies an element within a definition file. The ID needs to be a unique value within the definition.|
|RowLifespan||(Required) Set this attribute to a number that specifies how many days a data row can live in the Tme Machine before being purged. For example, if the row lifespan value is 7, all data rows more than one week old get purged.|
|TimeStampColumn||Set this attribute to a date column from the source table to indicate that the Time Machine table should use the date column specified as the time-stamp column. By default, Logi Mart will populate the time-stamp column with the current date and time if no column is specified here.|
|UniqueIdentifierDataColumn||(Required) Specify the name of a column in the source table that acts as a primary key. Logi Intelligence Server will use this column to identify new rows added to the source table that are not present in the data mart table.
NOTE: Use the @Function.UniqueIdentifierValue~ token to retrieve the current unique identifier column value for this IncrementalAppend element.|
