---------------------------------------
Summary: Gremlin VM repeat/until/emit flows do not respect barriers
Key: TINKERPOP-3002
URL: https://issues.apache.org/jira/browse/TINKERPOP-3002
Project: TinkerPop
Issue Type: Bug
Components: process
Reporter: Lyndon Bauto
Assignee: Lyndon Bauto
I detailed some of the information here
[https://discord.com/channels/838910279550238720/1151590132021997598/1151590132021997598]
but the short version of what I have found is that if you have a flow like:
```
g.V().repeat(barrier().out()).until(barrier().out().count().is(P.eq(0))).toList()
```
What ends up happening in the `barrier()` step inside the `until` block will
have items trickle in 1 at a time, while the `barrier()` in the `repeat` block
will have all the items come in at once. So in otherwords the control flow of
the `repeat`/`emit`/`until` flow will not respect barriers injected inside the
`until`/`emit` blocks.

In my use case (and the use case I suspect others have) barriers are used
heavily in movement which is where these `repeat` flows are often used.
