I'm still very much interested in an answer to any of my questions below. Help is much appreciated.
-- Andreas I'm trying to split up a monolithic couchdb instance into individual instances using filtered replication (following http://wiki.apache.org/couchdb/Replication). (1) Using 1.1.1 pull replication fails after a while with (I suspect due to COUCHDB-1289): [Tue, 05 Jun 2012 22:20:39 GMT] [error] [<0.31594.186>] changes loop timeout, no data received from http://localhost:5984/source/ [Tue, 05 Jun 2012 22:20:39 GMT] [error] [<0.31594.186>] ** Generic server <0.31594.186> terminating ** Last message in was changes_timeout ** When Server state == {state,nil,nil, [<0.31569.186>, {http_db,"http://localhost:5984/source/";,[], "_changes", [{"User-Agent","CouchDB/1.1.1"}, {"Accept","application/json"}], [{"filter",<<"queries/target">>}, {"style",all_docs}, {"heartbeat",10000}, {"since",0}, {"feed",normal}], get,nil, [{stream_to,{<0.31594.186>,once}}, {response_format,binary}], 10,500,<0.31595.186>}, 0, [{<<"source">>, <<"http://localhost:5984/source";>>}, {<<"target">>, <<"http://...@localhost:5984/target";>>}, {<<"filter">>,<<"queries/target">>}]], 39982,<0.31595.186>, {1338,934681,255278}, false,0,<<>>, {<0.31598.186>,#Ref<0.0.191.224241>}, {[],[]}, nil} ** Reason for termination == ** changes_timeout Question: Is there a 1.1.1 version that has this issue fixed? Question: What patches would I need to apply to make it work? There are 3 different patches linked in COUCHDB-1289. Do I need all 3? (2) Using 1.2 pull replication from the same 1.1.1 source via ssh tunneling fails as well: [Mon, 04 Jun 2012 23:27:50 GMT] [info] [<0.7389.0>] recording a checkpoint for `http://localhost:5986/source/` -> `http://...:*****@localhost:5984/target/` at source update_seq 39982 [Mon, 04 Jun 2012 23:27:50 GMT] [info] [<0.7268.0>] 127.0.0.1 - - PUT /target/_local/9dcc3b03231843cea27bcd33ace50d51 201 [Mon, 04 Jun 2012 23:27:59 GMT] [error] [<0.7400.0>] Replicator, request GET to "http://localhost:5986/source/_changes?filter=queries%2Ftarget&feed=normal&style=all_docs&since=0&heartbeat=10000"; failed due to error req_timedout [Mon, 04 Jun 2012 23:27:59 GMT] [info] [<0.7400.0>] Retrying _changes request to source database http://localhost:5986/source/ with since=39982 ...

Question: What other options do I have to make it work? (3) I would like to combine the filtered replication with continuous replication, but when I do: curl -H 'Content-Type: application/json' -X POST -d '{"source":"http://localhost:5986/source","target":"http://...@localhost:5984/target","filter":"queries/target","continuous":"true"}' http://localhost:5984/_replicate then I see the following error: {"error":"case_clause","reason":"true"} and in the logs: [Tue, 05 Jun 2012 23:04:04 GMT] [error] [<0.258.0>] Uncaught error in HTTP request: {error, {case_clause,<<"true">>}} [Tue, 05 Jun 2012 23:04:04 GMT] [info] [<0.258.0>] Stacktrace: [{couch_replicator_utils, '-maybe_append_options/2-fun-0-',3, [{file,"couch_replicator_utils.erl"}, {line,143}]}, {lists,foldl,3, [{file,"lists.erl"},{line,1197}]}, {couch_replicator_utils,replication_id,1, [{file,"couch_replicator_utils.erl"}, {line,55}]}, {couch_replicator_utils,parse_rep_doc,2, [{file,"couch_replicator_utils.erl"}, {line,49}]}, {couch_httpd_replicator,handle_req,1, [{file,"couch_httpd_replicator.erl"}, {line,34}]}, {couch_httpd,handle_request_int,5, [{file,"couch_httpd.erl"},{line,317}]}, {mochiweb_http,headers,5, [{file,"mochiweb_http.erl"},{line,136}]}, {proc_lib,init_p_do_apply,3, [{file,"proc_lib.erl"},{line,227}]}] [Tue, 05 Jun 2012 23:04:04 GMT] [error] [<0.258.0>] Uncaught server error: {case_clause,<<"true">>} [Tue Question: Is this possible now? Question: Could this be possible in the future? Any advise on how to approach this differently is very welcome as well. Also, please let me know if I can provide more information. Thanks in advance. -- Andreas
