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.
Returns the result of this query as an RDD[InternalRow] by delegating to doExecute after
preparations.
Returns the result of this query as an RDD[InternalRow] by delegating to doExecute after
preparations.
Concrete implementations of SparkPlan should override doExecute.
Returns the result of this query as a broadcast variable by delegating to doExecuteBroadcast
after preparations.
Returns the result of this query as a broadcast variable by delegating to doExecuteBroadcast
after preparations.
Concrete implementations of SparkPlan should override doExecuteBroadcast.
Runs this query returning the result as an array.

Execute a query after preparing the query and adding query plan information to created RDDs for visualization.
Execute a query after preparing the query and adding query plan information to created RDDs for visualization.
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).
Return a LongSQLMetric according to the name.
Return a LongSQLMetric according to the name.

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.
Blocks the thread until all subqueries finish evaluation and update the results.
Blocks the thread until all subqueries finish evaluation and update the results.
Co-groups the data from left and right children, and calls the function with each group and 2 iterators containing all elements in the group from left and right side. The result of this function is flattened before being output.
