Generate the Java source code to process the rows from child SparkPlan.
Generate the Java source code to process the rows from child SparkPlan.
This should be override by subclass to support codegen.
For example, Filter will generate the code like this:
# code to evaluate the predicate expression, result is isNull1 and value2 if (isNull1 || !value2) continue; # call consume(), which will call parent.doConsume()
Note: A plan can either consume the rows as UnsafeRow (row), or a list of variables (input).
Overridden by concrete implementations of SparkPlan.
Overridden by concrete implementations of SparkPlan. Produces the result of the query as an RDD[InternalRow]
Overridden by concrete implementations of SparkPlan.
Overridden by concrete implementations of SparkPlan. Produces the result of the query as a broadcast variable.
Overridden by concrete implementations of SparkPlan.
Overridden by concrete implementations of SparkPlan. It is guaranteed to run before any
execute of SparkPlan. This is helpful if we want to set up some state before executing the
query, e.g., BroadcastHashJoin uses it to broadcast asynchronously.
Note: the prepare method has already walked down the tree, so the implementation doesn't need to call children's prepare methods.
This will only be called once, protected by this.
Produce code to process the input iterator as ColumnarBatches.
Produce code to process the input iterator as ColumnarBatches. This produces an UnsafeRow for each row in each batch.

Returns the result of this query as an RDD[InternalRow] by delegating to doExecute after
preparations.

after preparations.

Runs this query returning the first n rows as an array.
Runs this query returning the first n rows as an array.
This is modeled after RDD.take but never runs any job locally on the driver.
Runs this query returning the result as an iterator of InternalRow.
Runs this query returning the result as an iterator of InternalRow.
Note: this will trigger multiple jobs (one for each partition).
Returns all the RDDs of InternalRow which generates the input rows.
Returns all the RDDs of InternalRow which generates the input rows.
Note: right now we support up to two RDDs.
For optimization to suppress shouldStop() in a loop of WholeStageCodegen.
For optimization to suppress shouldStop() in a loop of WholeStageCodegen. Returning true means we need to insert shouldStop() into the loop producing rows, if any.
Return a LongSQLMetric according to the name.
Return a LongSQLMetric according to the name.

Set to false if this plan consumes all rows produced by children but doesn't output row to buffer by calling append(), so the children don't require shouldStop() in the loop of producing rows.

A handle to the SQL Context that was used to create this plan.
A handle to the SQL Context that was used to create this plan. Since many operators need access to the sqlContext for RDD operations or configuration this field is automatically populated by the query planning infrastructure.
