Steven Hawkins resolved TEIIDSB-121.
------------------------------------
Resolution: Cannot Reproduce
I'm not able to reproduce this based upon what's here. If there's a way to provide a sanitized edm file that would be best. Locally I generated a schema from 100 views defined as:
create view v0 (col1 integer primary key , col2 integer, .. col100 integer, foreign key (col1) references v1(col1), .. foreign key (col10) references v10(col1)) as SELECT 1, ...;
So that's 100 views each with 100 columns and 10 relationships and I can't get to what you are describing. From what I can see there is simple linear scaling in the generation time from there - scaling out to 200 views roughly doubles the time.

> Priority: Major

> When i get request as
> http://localhost:8080/odata/swagger.json or http://localhost:8080/odata/datasource/Account/swagger.json or http://localhost:8080/odata/datasource/swagger.json
> cpu utilization 100% and i do not get any response.
> We have 2 bad approach:
> 1. In org.teiid.olingo.web.OpenApiHandler:151 teiid create tmp file in filesystem.
> Its bad because in Docker k8s systems applications can't create any files in FS.
> 2. In org.apache.xalan.transformer.TransformerImpl:709 we get system freeze (CPU utilization 100% infinite)
