        Setting this value states whether existing indexes should be
        automatically updated after an append operation or recomputed
        after an index-invalidating operation (i.e. removal and
        modification of rows).  The default is true.

        This value gets into effect whenever a column is altered.  If you
        don't have automatic indexing activated and you want to do an
        immediate update use `Table.flush_rows_to_index()`; for an immediate
        reindexing of invalidated indexes, use `Table.reindex_dirty()`.

        This value is persistent.
