    Incremental refresh on 60m records data source so slow

    Anders Lars

      Hey - I have a 60 million record data source with about 40 fields, most of which are pretty narrow. A full refresh takes 1.3 hours to complete. the incremental takes 1.5 - 2+ hours to load 120k new records daily.. the incremental is keyed off of an incrementing datetime field. No updates ever required. Is this normal? Seems like it might be more work for tableau to de-compress and update its indexes than it is to load everything.
