Ok, i have additionnal data. We have simple odata4 facade for jdbc connection (with using teiid spring-odata and teiid-spring-boot-starter).
1. Metadata size is 650kb in xml odata Edm format
2. 40 tables
3. ~100 columns in table (max)
4. 1 core in k8s cluster node and 1G memory

And i can't get swagger.json at all. Only CPU utilization 100%.

>          Issue Type: Bug
>          Components: datasource, OData
>    Affects Versions: 1.2.0
>            Reporter: Renat Eskenin
>            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)
