createReader

public BulkFormat.Reader<T> createReader(Configuration config,
                                         FileSourceSplit split)
                                  throws IOException

Deprecated.

Description copied from interface: BulkFormat

Creates a new reader that reads from the split's path starting at the split's offset and reads length bytes after the offset.

Specified by:

createReader in interface BulkFormat<T,FileSourceSplit>

Throws:

IOException

restoreReader

public BulkFormat.Reader<T> restoreReader(Configuration config,
                                          FileSourceSplit split)
                                   throws IOException

Deprecated.

Description copied from interface: BulkFormat

Creates a new reader that reads from split.path() starting at offset and reads until length bytes after the offset. A number of recordsToSkip records should be read and discarded after the offset. This is typically part of restoring a reader to a checkpointed position.

Specified by:

restoreReader in interface BulkFormat<T,FileSourceSplit>

Throws:

IOException

isSplittable

public boolean isSplittable()

Deprecated.

Description copied from interface: BulkFormat

Checks whether this format is splittable. Splittable formats allow Flink to create multiple splits per file, so that Flink can read multiple regions of the file concurrently.

See top-level JavaDocs (section "Splitting") for details.

Specified by:

isSplittable in interface BulkFormat<T,FileSourceSplit>

getProducedType

public TypeInformation<T> getProducedType()

Deprecated.

Description copied from interface: BulkFormat

Gets the type produced by this format. This type will be the type produced by the file source as a whole.

Specified by:

getProducedType in interface ResultTypeQueryable<T>

Specified by:

getProducedType in interface BulkFormat<T,FileSourceSplit>

Returns:

The data type produced by this function or input format.
