Subject [jira] [Closed] (UIMA-5180) UIMA-AS: service returns list of performance metrics in an inconsistent order
Date Wed, 16 Nov 2016 20:07:58 GMT

     [ https://issues.apache.org/jira/browse/UIMA-5180?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jerry Cwiklik closed UIMA-5180.
-------------------------------
    Resolution: Fixed

Modified to use TreeMap for storing AE performance metrics. This map is iterated over when
constructing a performance metrics list for an outgoing CAS. Since TreeMaps are sorted on
a key, each list of AEs is consistent

> Performance metrics list returned to the client does not preserve consistent order in
deployments using concurrent process threads. For example if there are two pipelines  containing
AE1, AE2, AE3, the service sends metrics list as: AE2, AE1, AE3 for CAS1  and for CAS2 it
returns AE3, AE1, AE2. The order of AEs in the list should be consistent across all CASes.
