----------------------------------
Summary: Optimise path parsing
Key: OAK-1015
URL: https://issues.apache.org/jira/browse/OAK-1015
Project: Jackrabbit Oak
Issue Type: Sub-task
Components: core
Reporter: Michael Dürig
As Jukka [mentioned |
https://issues.apache.org/jira/browse/OAK-978?focusedCommentId=13751242&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13751242]
on OAK-978, is often on the critical path and the changes done there had a bad
impact on performance:
{code}
Apache Jackrabbit Oak
# ReadPropertyTest min 10% 50% 90% max N
Jackrabbit 4 5 5 6 14 11287
Oak-Tar 14 15 16 16 27 3855
{code}
Until we are able to come up with a better solution that separates parsing from
name mapping, I suggest to use the following heuristic to shortcut path
parsing: shortcut iff the JCR path does not start with a dot, does not contain
any of {}[]/ and if it contains a colon the session does not have local
re-mappings.
