Summary: Cache journalFormatVersionToWrite when starting Journal
Key: BOOKKEEPER-1050
URL: https://issues.apache.org/jira/browse/BOOKKEEPER-1050
Project: Bookkeeper
Issue Type: Improvement
Reporter: Matteo Merli
Assignee: Matteo Merli
Priority: Minor
Fix For: 4.5.0
Reading the journal version format from {{ServiceConfiguration}} each time is
inefficient.
{{ServiceConfiguration}} is based on Java properties which is based on a String
to object hashtable. Each read implies acquiring a mutex and converting from
object to int.
