[jira] [Created] (KARAF-3075) AdminService should avoid writing
file in case just read instance status
Freeman Fang created KARAF-3075:
-----------------------------------
Summary: AdminService should avoid writing file in case just read instance status
Key: KARAF-3075
URL: https://issues.apache.org/jira/browse/KARAF-3075
Project: Karaf
Issue Type: Improvement
Reporter: Freeman Fang
For an instance, admin:list will write underlying cfg file 9 times for each instance, that said, if we have 3 child instance with 1 root instance, "admin:list" will cause 36 times file write which is a significant performance lost as well as more chance to corrupt the cfg file.
For some operations in AdminService like get***Port, getInstance, getStatus, which are read-only operations, we should avoid writing back to the cfg file after read
