Class ChunkLinkFetchResult

java.lang.Object

com.databricks.jdbc.model.core.ChunkLinkFetchResult

public class ChunkLinkFetchResult
extends Object

Result of fetching chunk links from the server.

Contains the fetched chunk links and continuation information for both SEA and Thrift protocols:

• SEA: Uses chunkIndex for continuation, hasMore derived from nextChunkIndex on last link
• Thrift: Uses rowOffset for continuation, hasMore from server's hasMoreRows flag

Each ExternalLink contains chunkIndex, rowCount, rowOffset, and the download URL.

Method Summary

Modifier and Type	Method	Description
static ChunkLinkFetchResult	endOfStream()	Creates a result indicating the end of the stream (no more chunks).
List<ExternalLink>	getChunkLinks()	Returns the list of external links fetched in this batch.
long	getNextFetchIndex()	Returns the next chunk index to fetch from.
long	getNextRowOffset()	Returns the next row offset for Thrift FETCH_ABSOLUTE continuation.
boolean	hasMore()	Returns whether more chunks are available after this batch.
boolean	isEndOfStream()	Checks if this result represents the end of the chunk stream.
static ChunkLinkFetchResult	of(List<ExternalLink> links, boolean hasMore, long nextFetchIndex, long nextRowOffset)	Creates a result with the given links and continuation info.

Method Detail

of

public static ChunkLinkFetchResult of(List<ExternalLink> links,
                                      boolean hasMore,
                                      long nextFetchIndex,
                                      long nextRowOffset)

Creates a result with the given links and continuation info.

Parameters:

links - The fetched external links (each contains chunkIndex, rowCount, rowOffset, URL)

hasMore - Whether more chunks are available

nextFetchIndex - The next chunk index to fetch from, or -1 if no more

nextRowOffset - The next row offset for Thrift FETCH_ABSOLUTE

Returns:

A new ChunkLinkFetchResult

endOfStream

public static ChunkLinkFetchResult endOfStream()

Creates a result indicating the end of the stream (no more chunks).

Returns:

A ChunkLinkFetchResult representing end of stream

getChunkLinks

public List<ExternalLink> getChunkLinks()

Returns the list of external links fetched in this batch.

Returns:

List of ExternalLink, may be empty

hasMore

public boolean hasMore()

Returns whether more chunks are available after this batch.

Returns:

true if more chunks can be fetched, false otherwise

getNextFetchIndex

public long getNextFetchIndex()

Returns the next chunk index to fetch from.

Returns:

The next fetch index, or -1 if no more chunks

getNextRowOffset

public long getNextRowOffset()

Returns the next row offset for Thrift FETCH_ABSOLUTE continuation.

Returns:

The next row offset, or 0 if not applicable

isEndOfStream

public boolean isEndOfStream()

Checks if this result represents the end of the chunk stream.

Returns:

true if no more chunks are available
