-------------------------------------
Summary: Add optimistic transaction semantics to the verify stage
Key: USERGRID-52
URL: https://issues.apache.org/jira/browse/USERGRID-52
Project: Usergrid
Issue Type: Bug
Components: Stack
Reporter: David Johnson
Add an optimistic versioning verification stage into our write path. The write
should start as it normally does. If the version was included on the entity
write operation (delete or write) we need to read back the entity log, and
ensure that our "new" version is the only version entry since the last commit.
If not, fail fast, signal to the user their entity is "stale".
