The problem about jackrabbit,please help.
Hello, all
We are research jackrabbit 2.5.2, then we find some problems on cluster need your help.
1) Jackrabbit use lucene for metadata search, but it cannot support distributed queries, then the cluster need synchronize the index file of lucene to each node of cluster. The index file for each node is the whole data, so the performance for search will more and more slowly. (we have over 30 million records)
2) When we search the records which doc_state='1' with 1 million records one node, the service will hang. The search sql like this:
SELECT *
FROM [nt:unstructured] AS s
WHERE ISDESCENDANTNODE(s, [/root]) and doc_state='1'
3) If we remove the lucene in jackrabbit, change the key-value mode, to use the CRUD mode and relational tables of database to replace them. Does this method feasible? Does the architecture of jackrabbit be damaged if we do this?
Please help us to give some explanation, Thanks for your help.

Ni Hao Ouyangshu,
I suggest you to post the question to the user@ ML in order to get
more chances of a helpful reply, since dev@ is where Jackrabbit
developers discuss about Jackrabbit development.
HTH, zai jihan!
