Class Rewrite

java.lang.Object

com.lancedb.lance.operation.Rewrite

All Implemented Interfaces:

Operation

public class Rewrite
extends Object
implements Operation

Rewrite operation for reorganizing data without changing content. This operation rewrites the data but does not modify the content, e.g. for compaction or reordering. This modifies the addresses of existing rows, so indices that cover rewritten fragments need to be remapped.
