Re: [I] insert overwrite table will delete entire data [hudi]

nsivabalan commented on issue #15878:
URL: https://github.com/apache/hudi/issues/15878#issuecomment-4795496195

   This was fixed in 0.14.0 by [HUDI-6466](https://issues.apache.org/jira/browse/HUDI-6466) / PR #9113 (commit d67455a4a713). The fix introduced `hoodie.datasource.overwrite.mode` (STATIC/DYNAMIC) and also respects Spark's `spark.sql.sources.partitionOverwriteMode`, aligning Hudi's `INSERT OVERWRITE` semantics with Spark/Iceberg/Delta. In DYNAMIC mode, only the partitions present in the source data are overwritten — the rest of the table is preserved. The deducing logic lives in `ProvidesHoodieConfig.deduceOverwriteConfig` and is present on master. Closing — please reopen with a repro on a 0.14.0+ release if you still see the entire table being cleared with dynamic partition mode.
