Hello Iceberg devs!
After going through the mail threads (especially "Spark version support
strategy") and relevant PRs - it looks like - *Merge on Read* Support (ie.,
Spark writers writing equality deletes) will be available with
*Iceberg **+ Spark
3.2*. Is this understandi

Hello devs,
We are trying to implement Spark support for the merge-on-read feature in
Iceberg. Can you please share the elaborate plan here, ongoing work and
tentative timelines for the same (both from spark and iceberg repos side).
We are following the priority board that has been set up
merge: It uses filter API and also need

Dear Iceberg Dev:
As I said in the document[1] before, we think the iceberg update/delete
features (mainly merge-on-read) is the high
priority feature (we've also discussed some flink+iceberg scenarios and
anybody who interest that part can read
the document).
Recently, I write some demo

data has been ingested.
From there it is easy to imagine having a replace operator where file2’s
version of a column replaces file1’s version.

What do you mean by merge on read?
A few people I've talked to are interested in building delete and upsert
features. Those would create files that track the changes, which would be
merged at read time to apply them. Is that what you mean?
