I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as

for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is
still Minor, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.

> Key: FLINK-4688
> URL: https://issues.apache.org/jira/browse/FLINK-4688
> Project: Flink
> Issue Type: Bug
> Components: API / DataSet
> Affects Versions: 1.1.3, 1.2.0
> Reporter: Fabian Hueske
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor
> Attachments: stacktrace_32minsAfterSubmission.java,
> stacktrace_76minsAfterSubmission.java, stacktrace_shortlyAfterSubmission.java
>
>
> When optimizing a plan with many operators (more than 250), the optimizer
> gets stuck for hours.
> A user reported this problem on the [email protected] list [1] and provided
> stacktraces taken at different points in time (shortly after submission, 32
> minutes and 76 minutes after submission) (see attachments).
> The stacktraces show deeply recursive {{hasDamOnPathDownTo()}} calls. Maybe
> it is possible to improve the performance by caching the results?
