Ted Yu created KYLIN-3317: ----------------------------- Summary: Replace UUID.randomUUID with deterministic PRNG Key: KYLIN-3317 URL: https://issues.apache.org/jira/browse/KYLIN-3317 Project: Kylin Issue Type: Task Reporter: Ted Yu
Currently UUID.randomUUID is called in various places in the code base. * It is non-deterministic. * It uses a single secure random for UUID generation. This uses a single JVM wide lock, and this can lead to lock contention and other performance problems. We should move to something that is deterministic by using seeded PRNGs -- This message was sent by Atlassian JIRA (v7.6.3#76005)
