Resolution: Fixed
Fixed in commit 5dea1caffebd89b91b538218dc751c7b62c63773
> Regression in schema compilation memory requirements
> ----------------------------------------------------
>
> Key: DAFFODIL-2572
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2572
> Project: Daffodil
> Issue Type: Bug
> Components: Performance
> Reporter: Steve Lawrence
> Assignee: Steve Lawrence
> Priority: Major
> Fix For: 3.2.0
>
>
> I have a fairly large schema that compiles successfully on 3.1.0 with 200MB
> of memory given to the JVM.
> With the current main branch, I have to bump the memory up to 1300MB before
> it compiles, otherwise I get an OutOfMemoryException. This is about a 7x bump
> in memory.
> Git bisect pinpointed the regression to commit
> 62ac1047a18979bea1f5d6c668eefeaaae39d64b
> Skimming that commit, nothing immediately jumps out at me as a significant
> change to what we already did, so I'm not sure exactly what caused this
> regression.
