gerashegalov opened a new pull request, #17199: URL: https://github.com/apache/iceberg/pull/17199
Follow-up to #16154. ### What changes were made in this PR? Backport the Spark 4.1 session-level split-size override to Spark 3.5 and Spark 4.0. This adds `spark.sql.iceberg.read.split-size` support in the older Spark shims by wiring the session configuration into `SparkReadConf.splitSizeOption()` and `SparkReadConf.splitSize()`. ### Why this shape? This follows the Spark backport pattern discussed in review: land and review the change first in the latest Spark version, then copy the reviewed implementation to older supported Spark versions in a follow-up PR. Recent examples include #16344 and #16245, which backported Spark changes to older shim versions in a single follow-up PR. ### How was this patch tested? - `git diff --check` - `./gradlew -DsparkVersions=3.5 -DscalaVersion=2.12 :iceberg-spark:iceberg-spark-3.5_2.12:test --tests org.apache.iceberg.spark.TestSparkReadConf --tests org.apache.iceberg.spark.source.TestSparkScan` - `./gradlew -DsparkVersions=3.5 -DscalaVersion=2.13 :iceberg-spark:iceberg-spark-3.5_2.13:test --tests org.apache.iceberg.spark.TestSparkReadConf --tests org.apache.iceberg.spark.source.TestSparkScan` - `./gradlew -DsparkVersions=4.0 -DscalaVersion=2.13 :iceberg-spark:iceberg-spark-4.0_2.13:test --tests org.apache.iceberg.spark.TestSparkReadConf --tests org.apache.iceberg.spark.source.TestSparkScan` - `./gradlew -DsparkVersions=3.5 -DscalaVersion=2.12 :iceberg-spark:iceberg-spark-3.5_2.12:spotlessCheck :iceberg-spark:iceberg-spark-3.5_2.12:checkstyleMain :iceberg-spark:iceberg-spark-3.5_2.12:checkstyleTest` - `./gradlew -DsparkVersions=4.0 -DscalaVersion=2.13 :iceberg-spark:iceberg-spark-4.0_2.13:spotlessCheck :iceberg-spark:iceberg-spark-4.0_2.13:checkstyleMain :iceberg-spark:iceberg-spark-4.0_2.13:checkstyleTest` --- **AI Disclosure** - Model: GPT-5 / Codex - Platform/Tool: OpenAI Codex - Human Oversight: fully reviewed - Prompt Summary: Helped identify Spark backport precedent and implement the Spark 3.5/4.0 follow-up PR for the session-level split-size override. -- This is an automated message from the Apache Git Service.
