---|
Classes in org.apache.pig with annotations of type InterfaceAudience.Public | |
---|---|
interface |
Accumulator<T>
An interface that allows UDFs that take a bag to accumulate tuples in chunks rather than take the whole set at once. |
interface |
Algebraic
An interface to declare that an EvalFunc's calculation can be decomposed into intitial, intermediate, and final steps. |
interface |
CollectableLoadFunc
This interface implemented by a LoadFunc implementations indicates to
Pig that it has the capability to load data such that all instances of a key
will occur in same split. |
class |
ComparisonFunc
Deprecated. |
class |
EvalFunc<T>
The class is used to implement functions to be applied to fields in a dataset. |
class |
Expression
A class to communicate Filter expressions to LoadFuncs. |
class |
FileInputLoadFunc
This class provides an implementation of OrderedLoadFunc interface which can be optionally re-used by LoadFuncs that use FileInputFormat, by having this as a super class |
class |
FileSplitComparable
This class represents a relative position in a file. |
class |
FilterFunc
|
class |
FuncSpec
Class to represent a UDF specification. |
interface |
IndexableLoadFunc
This class is intended for use by LoadFunc implementations which have an internal index for sorted data and can use the index to support merge join in Pig. |
interface |
LoadCaster
An interface that provides cast implementations for load functions. |
class |
LoadFunc
A LoadFunc loads data into Pig. |
interface |
LoadMetadata
This interface defines how to retrieve metadata related to data to be loaded. |
interface |
LoadPushDown
This interface defines how to communicate to Pig what functionality can be pushed into the loader. |
static class |
LoadPushDown.RequiredField
Describes a field that is required to execute a scripts. |
static class |
LoadPushDown.RequiredFieldList
List of fields that Pig knows to be required to executed a script. |
static class |
LoadPushDown.RequiredFieldResponse
Indicates whether the loader will return the requested fields or all fields. |
interface |
OrderedLoadFunc
Implementing this interface indicates to Pig that a given loader can be used for MergeJoin. |
class |
PigServer
A class for Java programs to connect to Pig. |
interface |
PigToStream
The interface used for the custom mapping of a Tuple to a byte
array. |
class |
ResourceSchema
A represenation of a schema used to communicate with load and store functions. |
class |
ResourceStatistics
An class that represents statistics about data to be loaded or stored. |
class |
SortColInfo
A class representing information about a sort column in SortInfo |
class |
SortInfo
Class to communicate sort column information based on order by statment's sort columns and schema |
class |
StoreFunc
StoreFuncs take records from Pig's processing and store them into a data store. |
interface |
StoreFuncInterface
StoreFuncs take records from Pig's processing and store them into a data store. |
interface |
StoreMetadata
This interface defines how to write metadata related to data to be stored. |
interface |
StreamToPig
The interface is used for the custom mapping of a byte array, received from the stdout of the streaming process, to a Tuple . |
