Danny Chen commented on HUDI-2752:
----------------------------------

I found that these two issue are a little different, in one batch, if there are disorder delete messages, the data would lost because the append handle always write insert data block before the delete block, so re-open it again ~

> Currently, the DELETE blocks are always written after the data blocks for one batch of data write, when there are INSERT/UPDATEs after the DELETE, the data would lost.
> What i can thought of is that the DELETE block should at least keep the event time sequence for #preCombine with other record payloads.
