Package io.trino.plugin.hive.fs

Class TransactionScopeCachingDirectoryLister

java.lang.Object

io.trino.plugin.hive.fs.TransactionScopeCachingDirectoryLister

All Implemented Interfaces:

DirectoryLister, TableInvalidationCallback

public class TransactionScopeCachingDirectoryLister
extends Object
implements DirectoryLister

Caches directory content (including listings that were started concurrently). TransactionScopeCachingDirectoryLister assumes that all listings are performed by same user within single transaction, therefore any failure can be shared between concurrent listings.
