Example 9 with PipelinePhase

use of co.cask.cdap.etl.common.PipelinePhase in project cdap by caskdata.

the class PipelinePlanner method plan.

/**
 * Create an execution plan for the given logical pipeline. This is used for batch pipelines.
 * Though it may eventually be useful to mark windowing points for realtime pipelines.
 *
 * A plan consists of one or more phases, with connections between phases.
 * A connection between a phase indicates control flow, and not necessarily
 * data flow. This class assumes that it receives a valid pipeline spec.
 * That is, the pipeline has no cycles, all its nodes have unique names,
 * sources don't have any input, sinks don't have any output,
 * everything else has both an input and an output, etc.
 *
 * We start by inserting connector nodes into the logical dag,
 * which are used to mark boundaries between mapreduce jobs.
 * Each connector represents a node where we will need to write to a local dataset.
 *
 * Next, the logical pipeline is broken up into phases,
 * using the connectors as sinks in one phase, and a source in another.
 * After this point, connections between phases do not indicate data flow, but control flow.
 *
 * @param spec the pipeline spec, representing a logical pipeline
 * @return the execution plan
