Examples of ExecutionEngine

com.alibaba.wasp.plan.execute.ExecutionEngine
ExecutionEngine responsibility to execute QueryPlan, InserPlan, UpdatePlan and DeletePlan.
org.apache.pig.backend.executionengine.ExecutionEngine
TODO: provide a manner to generate/collect logging information for DBG purposes TODO: add keys for properties/statistics
org.neo4j.cypher.ExecutionEngine
org.neo4j.cypher.javacompat.ExecutionEngine
org.voltdb.jni.ExecutionEngine
Wrapper for native Execution Engine library. There are two implementations, one using JNI and one using IPC. ExecutionEngine provides a consistent interface for these implementations to the ExecutionSite.
