Alexey Loubyansky commented on WFCORE-695:
------------------------------------------

Bytes are attached only when deploy command is used in CLI batches. Otherwise, it's streams.

> 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

> 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.
