Description

In OAK-1395 we added limits for long running queries. In OAK-1571 we added OSGi configuration. In OAK-5237 we change the default settings.

It would be nice to be able to define the limits per query, similar to OAK-4888. The query would look like (for example, to limit reading to 1 million nodes, even if the default query limit is lower):

select * from [nt:base] 
where ischildnode('/oak:index') 
order by name()
option(traversal ok, limit 1000000)
