David Johnson created USERGRID-406:
--------------------------------------
Summary: HTTP POST of Entity fails under heavy load
Key: USERGRID-406
URL: https://issues.apache.org/jira/browse/USERGRID-406
Project: Usergrid
Issue Type: Bug
Reporter: David Johnson
When running UG2 under heavy we sometimes see the exception below when a new
Entity is created by an HTTP POST.
The problem seems to be that we write the Entity. Then when we
add-to-collection and validate the Entity, we read the Entity but it is not
ready for us to read yet -- so the read fails.
Instead of re-reading the Entity, we should pass the Entity that we created
down into the add-to-collection and validate methods. We should not need to
read the Entity in the processing of the request that created it.
