Class BaseMetadataTable

java.lang.Object

org.apache.iceberg.BaseMetadataTable

All Implemented Interfaces:

Serializable, Table

Direct Known Subclasses:

AllDataFilesTable, AllDeleteFilesTable, AllEntriesTable, AllFilesTable, AllManifestsTable, DataFilesTable, DeleteFilesTable, FilesTable, HistoryTable, ManifestEntriesTable, ManifestsTable, MetadataLogEntriesTable, PartitionsTable, PositionDeletesTable, RefsTable, SnapshotsTable

public abstract class BaseMetadataTable
extends Object
implements Serializable

Base class for metadata tables.

Serializing and deserializing a metadata table object returns a read only implementation of the metadata table using a StaticTableOperations. This way no Catalog related calls are needed when reading the table data after deserialization.
