> Support configuring object-reuse for internal operators
> -------------------------------------------------------
>
> Key: FLINK-32476
> URL: https://issues.apache.org/jira/browse/FLINK-32476
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / Task
> Reporter: Xuannan Su
> Priority: Minor
> Labels: auto-deprioritized-major, pull-request-available
>
> Currently, object reuse is disabled by default for streaming jobs in order to
> prevent unexpected behavior. Object reuse becomes problematic when the
> upstream operator stores its output while the downstream operator modifies
> the input.
> However, many operators implemented by Flink, such as Flink SQL operators, do
> not modify the input. This implies that it is safe to reuse the input object
> in such cases. Therefore, we intend to enable object reuse specifically for
> operators that do not modify the input.
> As the first step, we will focus on the operators implemented within Flink.
> We will create the FLIP to introduce the API that allows user-defined
> operators to enable object reuse in the future.
