| BatchTask
The base class for all batch tasks.
|
| Class and Description |
|---|
| BatchTask
The base class for all batch tasks.
|
| TaskContext
The task context gives a driver (e.g.,
MapDriver, or JoinDriver) access to the
runtime components and configuration that they can use to fulfil their task. |
| Class and Description |

| AbstractCachedBuildSideJoinDriver |
| AbstractOuterJoinDriver
The abstract outer join driver implements the logic of an outer join operator at runtime.
|
| DamBehavior
Enumeration for the different dam behaviors of an algorithm or a driver strategy.
|
| Driver
The interface to be implemented by all drivers that run alone (or as the primary driver) in a
task.
|
| DriverStrategy
Enumeration of all available operator strategies.
|
| JoinDriver
The join driver implements the logic of a join operator at runtime.
|
| ResettableDriver
This interface marks a
Driver as resettable, meaning that will reset part of their
internal state but otherwise reuse existing data structures. |
| TaskContext
The task context gives a driver (e.g.,
MapDriver, or JoinDriver) access to the
runtime components and configuration that they can use to fulfil their task. |
| TempBarrier
This class facilitates JVM-local exchange between stages of a batch job.
