[I] Spark SQL UPDATE and DELETE should write record positions [hudi]
hudi-bot opened a new issue, #17309:
URL: https://github.com/apache/hudi/issues/17309
Though there is no read and write error, Spark SQL UPDATE and DELETE do not write record positions to the log files.

Here is with optimized writes false:

21/Nov/24 22:07;jonvex;To unblock the release we can either do one of two things:
# Disable `hoodie.spark.sql.optimized.writes.enable`
## This will decrease performance of writes during keygen and index lookup
## Positions will be included in the updates
## we can check to see if positions are even enabled and only default it when position writing is disabled
# Keep the code as is
## This will decrease performance during read of uncompacted filegroups
## We have the ability to fallback when positions are missing and I have written extensive test cases to ensure that fallback works correctly in all combinations of log and base files
## This can also use some extra disk space during the read because we have to rewrite mappings in the spillable map, and deletes to the spillable map don't actually free up space until we close it
To actually write positions using the prepped workflow, I think there is a way to do this but will not be that easy:
# We will need to read _tmp_metadata_row_index inside the update and delete sql commands. Then during keygen, we will get the position from that field
## this will take some work because I don't think we have ever tried to read positions at the dataset level
# Then we will need to get the positions out during key generation
## this should be easy
# Then we will need to drop the column before we do the write
## this will probably be pretty easy

26/Nov/24 00:30;yihua;Deferring this to Hudi 1.1 since this does not cause correctness issue and adding positional updates and deletes in SQL UPDATE and DELETE needs design.;;;
---
10/Jan/25 00:18;yihua;In the UPDATE and DELETE command, we'll try creating the relation with a schema that has the row index meta column or a new hoodie meta column to attach the row index column to the return DF (this also requires the file group reader and parquet reader to keep the new row index column by fixing the wiring). In that way, we can pass the positions down to the prepped write flow and prepare the HoodieRecords with the current record location.;;;
---
10/Jan/25 01:59;yihua;I have a draft PR up which makes the prepped upsert flow write record positions to the log blocks from Spark SQL UPDATE statement. I'm going to fix a few issues before opening it up for review.;;;

Re: [I] Spark SQL UPDATE and DELETE should write record positions [hudi]

This issue was reviewed as part of the JIRA-migrated backlog triage (HUDI-8553).
**Findings: the linked PR has not merged; keeping this open.**
PR #12732 is still **open and unmerged**, so nothing has landed for this ticket. The `status:pr-available` label is accurate and should stay.
Two earlier attempts, PR #12612 and PR #12716, are both closed without merging - #12732 is the third and only live one. That history is worth reading before starting again.
Keeping this open until #12732 merges.
