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.
