Michael Dürig created OAK-175:
---------------------------------
Summary: MemoryNodeStateBuilder inefficient for large child node
lists
Key: OAK-175
URL: https://issues.apache.org/jira/browse/OAK-175
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Reporter: Michael Dürig
OAK-174 leverages the {{getChildBuilder()}} method introduced with OAK-170.
This revealed a performance issue for large child node list with the
{{MemoryNodeStateBuilder}} implementation: without additional measures (see
below) {{RootImplTest.largeChildList()}} is very slow.
The additional measures I currently implemented consist of counting the overall
number of changes to a tree and purge these down to the branch when a certain
threshold is reached. See {{RootImpl.purge()}}. However, I think this mechanism
is too ad-hoc and we should find a more general solution.
