Steve Niemitz created BEAM-7397: ----------------------------------- Summary: Avoid String.format in state namespace construction Key: BEAM-7397 URL: https://issues.apache.org/jira/browse/BEAM-7397 Project: Beam Issue Type: Improvement Components: runner-core Reporter: Steve Niemitz Assignee: Steve Niemitz
I've noticed that for jobs that access state frequently, a percent or two of overall CPU time is actually spent calculating the state namespace name. StateNamespaces.java uses a String.format for the window namespaces, but could simply use a string concatenation to do the same thing with much less overhead. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
