   Dear Polaris team,
   
   I would like to report that we are also encountering this issue (#1389) in 
our environment, specifically when running dbt (data build tool).
   
   dbt frequently executes parallel model builds, which generate exactly the 
kind of concurrent CREATE and DELETE operations on namespaces, tables, and 
views that trigger this IllegalStateException. This happens quite often in our 
pipelines and significantly hinders production use cases.
   
   The error rate increases with higher threads settings in dbt, forcing us to 
reduce parallelism significantly. We would be happy to test any preview fixes 
or provide more logs if needed.
   
   I wanted to share this real-world use case to highlight that this is not 
just an edge-case test scenario but a practical problem for users relying on 
dbt for data transformations. I hope this additional context helps in 
prioritizing the fix.
   
   Thank you for your work on Polaris!
   Csaba
