> 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
> Priority: Major
> Labels: query-engine
> 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)
