org.apache.paimon.fileindex.FileIndexReader

所有已实现的接口:

FunctionVisitor<FileIndexResult>, PredicateVisitor<FileIndexResult>

直接已知子类:

EmptyFileIndexReader

public abstract class FileIndexReader
extends Object
implements FunctionVisitor<FileIndexResult>

Read file index from serialized bytes. Return true, means we need to search this file, else means needn't.
