bigquery ingestion. |
BigQueryStoreResult<R> |
Result of bigQuery staging process.
|
BlobFileOutput |
An
Output that writes bytes to a set of blob files, one per shard. |
BlobFileOutputWriter |

GoogleCloudStorageFileOutputWriter |
An
OutputWriter that writes bytes to a GCS file that it creates. |
GoogleCloudStorageLevelDbOutput |
An composition of
GoogleCloudStorageFileOutput with
GoogleCloudStorageLevelDbOutput that pads blocks to GCS write boundaries on end of slice. |
GoogleCloudStorageLevelDbOutputWriter |
A decorator for LevelDbOutputWriter that delegates to
GoogleCloudStorageFileOutputWriter
and pads blocks to GCS write boundaries on end of slice. |
InMemoryOutput<O> |
An
Output that collects all values in memory and returns them on
InMemoryOutput.finish(java.util.Collection<? extends com.google.appengine.tools.mapreduce.OutputWriter<O>>) . |
InMemoryOutputWriter<O> | |
ItemSegmentingOutputWriter<O> |
Segments data by using a separate writer each time
ItemSegmentingOutputWriter.shouldSegment(O) returns true. |
LevelDbOutput<R> |
An
Output that writes LevelDb records. |
LevelDbOutputWriter |
An implementation of a LevelDb format writer.
|
MarshallingOutput<O,R> |
An
Output that marshalls records. |
MarshallingOutputWriter<O> |
An
OutputWriter that marshalls records. |
NoOutput<O,R> |
An
Output that throws an exception whenever an attempt is made to
write a value. |
ShardingOutputWriter<K,V,WriterT extends OutputWriter<KeyValue<K,V>>> |
Writes
KeyValue s out to a number of output writers each corresponding to a different
shard A sharder and an Output object are provided in the constructor. |
SizeSegmentedGoogleCloudStorageFileOutput |
An
Output that writes files to GCS segmented by specified size limit. |
SizeSegmentingOutputWriter |
Segments the output base on the specified size limit.
|
SliceSegmentingOutputWriter<O,WriterT extends OutputWriter<O>> |
Segments data by using a separate writer for each slice.
|
StringOutput<O,R> |
An output that accepts objects, invokes
Object.toString() (or an arbitrary
other String-valued Function that is Serializable ) on them,
adds an optional terminator, encodes the resulting String according to a
Charset , and writes the result to an underlying Output . |
