This parameter specifies the type of incremental updating which should be used for a database data source.

Available options are as follows :

  • none - Only full updates are performed

  • update_table - A table of update events is used to update the search index

  • incremental_sql - Information about previous updates (time and largest key seen) are used to select only new records

See the incremental SQL and update table name pages for more information on each option.
