Jean-Francois Denise commented on WFCORE-695:
---------------------------------------------
[~rsvoboda], it seems that one of the solution to solve this problem would have been to
evolve the CLI deploy command to rely on streams instead of serialising the content. If
that is the case, then one can now use the CLI in batch mode to deploy some large content
files.
[~brian.stansberry], would that fix the original reported issue, I guess yes (looking at
comments in this Jira).
OutOfMemoryErrors when adding large deployment with audit logging
enabled
-------------------------------------------------------------------------
Key: WFCORE-695
URL: https://issues.jboss.org/browse/WFCORE-695
Project: WildFly Core
Issue Type: Bug
Components: CLI, Domain Management
Affects Versions: 1.0.0.CR4
Reporter: James Livingston
Assignee: Jean-Francois Denise
When performing a deployment operation, audit logging will include the deployment content
in the audit record (serialised as text). Since
JsonAuditLogItemFormatter.createRecordText() creates the string in memory, large
deployment will lead to an OutOfMemoryError such as
java.lang.OutOfMemoryError: Java heap space

A work-around is increasing the controller heap size, but it would be good if that was
not required. If including the deployment content in the record is desired, perhaps there
is a way to make it stream the record rather than building the entire string in memory at
once.
