Changed Classes |
POCombinerPackage
|
The package operator that packages the globally rearranged tuples into output format after the combiner stage. |
PODemux
|
The MapReduce Demultiplexer operator. |
POFRJoin
|
The operator models the join keys using the Local Rearrange operators which are configured with the plan specified by the user. |
POForEach
|
|
POLoad
|
The load operator which is used in two ways: 1) As a local operator it can be used to load files 2) In the Map Reduce setting it is used to create jobs from MapReduce operators which keep the loads and stores in the Map and Reduce Plans till the job is created |
POLocalRearrange
|
The local rearrange operator is a part of the co-group implementation. |
POLocalRearrangeForIllustrate
|
The local rearrange operator is a part of the co-group implementation. |
POMultiQueryPackage
|
The package operator that packages the globally rearranged tuples into output format as required by multi-query de-multiplexer. |
POPackage
|
The package operator that packages the globally rearranged tuples into output format as required by co-group. |
POPreCombinerLocalRearrange
|
A specialized local rearrange operator which behaves like the regular local rearrange in the getNext() as far as getting its input and constructing the "key" out of the input. |
POSort
|
This implementation is applicable for both the physical plan and for the local backend as the conversion of physical to mapreduce would see the SORT operator and take necessary steps to convert it to a quantile and a sort job. |
POStore
|
The store operator which is used in two ways: 1) As a local operator it can be used to store files 2) In the Map Reduce setting it is used to create jobs from MapReduce operators which keep the loads and stores in the Map and Reduce Plans till the job is created |
POStoreImpl
|
This class is used to specify the actual behavior of the store operator just when ready to start execution. |
