Robert Varga created KARAF-5604: ----------------------------------- Summary: karaf:features-generate-descriptor takes long when faced with complex feature dependencies Key: KARAF-5604 URL: https://issues.apache.org/jira/browse/KARAF-5604 Project: Karaf Issue Type: Improvement Components: karaf-tooling Affects Versions: 4.1.3 Reporter: Robert Varga Fix For: 4.2.0, 4.1.5
Opendaylight's distribution-check jobs generate features which have complex feature dependencies, which exposes scaling issues in karaf:features-generate-descriptor. [https://github.com/opendaylight/integration-distribution/tree/master/features/singles/odl-integration-all] takes ~270 seconds to generate: real 4m28.834s user 3m40.287s sys 1m23.629s [https://github.com/opendaylight/integration-distribution/tree/master/features/repos/index] takes ~638 seconds to generate: real 10m38.859s user 7m55.004s sys 3m17.269s Running profiling shows that this time is dominated by short-lived FileInputStreams being generated at a rate of 7K-8Kps – which are coming from both feature reading and from artifact resolution. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
