Hello Robert, this is much closer to what I expect. I assume I should follow the procedure described here http://mail-archives.apache.org/mod_mbox/couchdb-dev/200811.mbox/%3cc397e43f-096f-4892-9519-383032622...@dionne-associates.com%3E
I will give it a try. Thank you very much. - Andrey P.S. I have already identified some redundant code ( https://issues.apache.org/jira/browse/COUCHDB-920). I hope I can further improve the code base when I am able to debug the running database.
