public class StoreCompactOperator
extends PrepareCommitOperator<org.apache.flink.table.data.RowData,Committable>

A dedicated operator for manual triggered compaction.

In-coming records are generated by sources built from CompactorSourceBuilder. The records will contain partition keys in the first few columns, and bucket number in the last column.
