ASF GitHub Bot commented on TINKERPOP-1863: ------------------------------------------- Github user robertdale commented on the issue: https://github.com/apache/tinkerpop/pull/771 VOTE +1 > 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. > https://lists.apache.org/thread.html/a7e6cfeadad10852a2deed8616e47df6738c13c47119c12f98dcd3e1@%3Cdev.tinkerpop.apache.org%3E -- This message was sent by Atlassian JIRA (v6.4.14#64029)
