--------------------------------------
Summary: Lift the 150 character limit on item names
Key: OAK-2644
URL: https://issues.apache.org/jira/browse/OAK-2644
Project: Jackrabbit Oak
Issue Type: Wish
Components: core
Affects Versions: 1.1.7, 1.0.12
Reporter: Felix Meschberger
Currently -- as of Oak 1.1.7 and 1.0.12 releases -- there is a limit on the
length of 150 characters for item names in Oak.
This limit seems to be based upon a limitation in the MongoDB MK implementation
because MongoDB has a limit of 1024 bytes (I think) for indexable properties.
I think this limitation is highly unexpected and seems to be largeyl
undocumented. For previous users of Jackrabbit it should probably at least be
documented on the [Backwards
Compatibility|http://jackrabbit.apache.org/oak/docs/differences.html] page.
The main problem, though, I have with this limit is, that it is based on a
limitation of a particular MK implementation and hits through the full stack. I
would have rather expected such a persistence limitation to be fully hidden and
handled inside the MK implementation.
Granted this limitation does not seem to violate the JCR 2.1 specification
which clearly states in section 3.2.4 Naming Restrictions:
bq. This definition of JCR name represents the least restrictive set of
constraints permitted for the naming of items and other entities. A repository
may further restrict the names of entities to a subset of JCR names and in most
cases is encouraged to do so.
and
bq. A writable repository may enforce any implementation-specific constraint by
causing an exception to be thrown on an invalid JCR write method call.
Still I think it is a questionable limitation for a generic repository where
such names may be auto-generated and thus be quite long depending on the use
case.
I understand this may be hard to fix but would still be happy to be able to
have (virtually) unlimited name length again as it was the case in Jackrabbit 2.
Thanks.
