Description

From Gremlin Users:

https://groups.google.com/d/msg/gremlin-users/wB0a9uP98Zw/zoZrNk8GFwAJ

gremlin> g.E().property("myprop", true).iterate()
gremlin> g.E().has("myprop").count().next()
==>6
gremlin> g.E().properties("myprop").drop().iterate()
gremlin> g.E().has("myprop").count().next()
==>5

Obviously, all "myprop" should get removed. The issue has to do with property equality from:

http://tinkerpop.apache.org/docs/3.4.5/upgrade/#_properties_equality

and LazyBarrierStrategy which bulks and yields just one property for drop():

gremlin> g.withoutStrategies(LazyBarrierStrategy).E().properties("myprop").drop()
gremlin> g.E().has("myprop").count().next()
==>0
