> Stream Cost Model and RelNode Cost Estimation
> ---------------------------------------------
>
> Key: BEAM-7777
> URL: https://issues.apache.org/jira/browse/BEAM-7777
> Project: Beam
> Issue Type: New Feature
> Components: dsl-sql
> Reporter: Alireza Samadianzakaria
> Assignee: Alireza Samadianzakaria
> Priority: Major
> Time Spent: 50m
> Remaining Estimate: 0h
>
> Currently the cost model is not suitable for streaming jobs. (it uses row
> count and for estimating the output row count of each node it is using
> calcite estimations that are only applicable to bounded data.)
> We need to implement a new cost model and implement cost estimation for all
> of our physical nodes.
