---------------------------------
Summary: Indexing job: optimize check for if a node is hidden
Key: OAK-10804
URL: https://issues.apache.org/jira/browse/OAK-10804
Project: Jackrabbit Oak
Issue Type: Improvement
Components: indexing
Reporter: Nuno Santos
While downloading the repository from Mongo, the indexing job has to discard
hidden entries. This is being done by a call to
`NodeStateUtils.isHiddenPath()`. This call is rather expensive, as it creates
an iterator over the path segments, which requires creating a new string for
each path segment. As the indexing job has to check every entry to verify if it
is hidden, this creates a significant overhead.
The implementation of checking for hidden paths can be replaced by a simple
search for {{"/:"}} in the string representing the path, which requires no
object allocation and should therefore be much faster.
