---------------------------------
Resolution: Not A Problem
> OPTION (LIMIT ...) doesn't prevent RuntimeNodeTraversalException
> ----------------------------------------------------------------
>
> Key: OAK-9929
> URL: https://issues.apache.org/jira/browse/OAK-9929
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: search
> Affects Versions: 1.44.0
> Reporter: Julian Reschke
> Priority: Major
>
> It appears that the concept of paging doesn't help when the result of the
> unpaged query exceeds the query limit.
> With >100K vanity paths and this query:
> {noformat}
> SELECT [sling:vanityPath], [sling:redirect], [sling:redirectStatus]
> FROM [nt:base] WHERE NOT isdescendantnode('/jcr:system')
> AND [sling:vanityPath] IS NOT NULL
> ORDER BY FIRST([sling:vanityPath]), [jcr:path] OPTION (LIMIT 1000)
> {noformat}
> I get the following exeption:
> {noformat}08.09.2022 14:19:38.945 *ERROR* [FelixDispatchQueue]
> org.apache.sling.resourceresolver.impl.CommonResourceResolverFactoryImpl
> activate: Cannot access repository, failed setting up Mapping Support
> org.apache.jackrabbit.oak.query.RuntimeNodeTraversalException: The query read
> or traversed more than 100000 nodes. To avoid affecting other tasks,
> processing was stopped.
