--------------------------------------
Summary: Implement Plan Fragmets support for ExecPlan.
Key: ARROW-14443
URL: https://issues.apache.org/jira/browse/ARROW-14443
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Alexander Ocsa
Assignee: Percy Camilo Triveño Aucahuasi
Fix For: 7.0.0
A plan fragment: Implement Plan Fragmets support for ExecPlan. A plan fragment:
* Has zero or more inputs and one or more outputs
* Is a logical description of how the output data should be generated based on
the input data.
* Is immutable during query runtime and can be shared and reused between
queries.
The relation between a plan fragment and a exec plan is: * An exec plan can be
executed on its own.
* A plan fragment allows to have some inputs that are not bound to any source
nodes and require some external entity to provide the data at runtime using the
push interface of ExecNodes (the external entity is related to DataHolder)
