-    See the note for update_row() on auto_increments and timestamps. This
-    case also applied to write_row().
-
     Called from item_sum.cc, item_sum.cc, sql_acl.cc, sql_insert.cc,
     sql_insert.cc, sql_select.cc, sql_table.cc, sql_udf.cc, and sql_update.cc.
 
     ADDITIONAL INFO:
 
-    Most handlers set timestamp when calling write row if any such fields
-    exists. Since we are calling an underlying handler we assume the´
-    underlying handler will assume this responsibility.
-
-    Underlying handlers will also call update_auto_increment to calculate
-    the new auto increment value. We will catch the call to
-    get_auto_increment and ensure this increment value is maintained by
-    only one of the underlying handlers.
+    We have to set timestamp fields and auto_increment fields, because those
+    may be used in determining which partition the row should be written to.
