vinishjail97 opened a new pull request, #847:
URL: https://github.com/apache/incubator-xtable/pull/847
## What
Documentation for the `xtable-spark-runtime` bundle (added in #843):
- **New docs page** `Run XTable on Apache Spark`
(`website/docs/spark-runtime.md`) — a `spark-submit` quickstart with worked
examples, the full CLI option table, a source/target format matrix, and Spark
version compatibility.
- **Module README** (`xtable-spark-runtime/README.md`) — build, usage,
compatibility, and how to run the bundle validation IT.
- Linked the new page from the **Installation** page and the docs sidebar
(Quick Start).
## Spark quickstart (excerpt)
```shell
$SPARK_HOME/bin/spark-submit \
--class org.apache.xtable.spark.XTableSparkSync \
--master 'local[*]' \
xtable-spark-runtime_2.12-<version>.jar \
--basepath /path/to/hudi_table \
--sourceformat HUDI \
--targets ICEBERG,DELTA
```
The docs also cover Spark version compatibility: Hudi/Iceberg sync is
Spark-free, and a Delta source/target auto-switches from `delta-core` (Spark
3.4) to the Spark-free Delta Kernel on Spark 3.5+.
## Note on merge order
This documents the `xtable-spark-runtime` module, which currently lives on
the #843 branch (targeting `branch-0.4`) and is not yet on `main`. Intended to
merge **after the 0.4.0 release**, once the module lands on `main`.
