> Delaying the setting of requestId till the RequestMessage instantiation time
> ----------------------------------------------------------------------------
>
> Key: TINKERPOP-1863
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1863
> Project: TinkerPop
> Issue Type: Improvement
> Components: driver
> Reporter: Eugene Chung
> Priority: Minor
>
> The Builder class of
> org.apache.tinkerpop.gremlin.driver.message.RequestMessage class sets its
> requestId field as UUID.randomUUID() by default.
> But I think it should be fixed not to be set by default. The reasons are
> below;
> - UUID.randomUUID() uses SecureRandom which grabs the lock at JVM level,
> which means whole threads calling this API compete against each other.
> - Getting random value from SecureRandom is somewhat CPU-intensive job.
> - If a gremlin client sends requestId by itself, the costs above are useless.
