All Implemented Interfaces:

UpdateEngine

Direct Known Subclasses:

UpdateEngineNonStreaming
```
public class UpdateEngineMain
extends UpdateEngineBase
```
Default implementation of an update engine based on stream updates to a worker function. In addition, it applies INSERT DATA and DELETE DATA driven off the updates, which may be directly from the parser.
Developers who only want to change/extend the processing of individual updates can easily

See UpdateEngineNonStreaming for a subclass that accumulates updates, including during parsing then executes the operation.
