Subject [jira] Commented: (COUCHDB-844) Documents missing after CouchDB restart
Date Sat, 07 Aug 2010 19:42:16 GMT


Lim Yue Chuan commented on COUCHDB-844:

I am pretty sure that the database I gave Damien and Chris has not been compacted. Its a pretty
small database, I can't think of any reason as to why I would compact it.

Looking at whats left of my data, I can see revision 1 of some documents I created really
early in development. So it might have been compacted at some point, but not recently before
the restart.

I however can recall compacting another database numerous times while trying to track down
a bug on the builtin reduce functions with Chris (
Afraid I can't say for sure that I have not lost data from that database as it is a log database
with mostly randomly generated data, but if I'd to guess, I would say that that would be the
case (no data loss).

> After a CouchDB restart, recently added/changed documents+designdocuments (min. 2 weeks
timeline!) are missing and cant be accessed trough REST Calls / Futon. 
> All documents that are still available trought REST/Futon only exist in old revisions.
> All documents/revisions can be found doing a manual search (less/egrep/...) in the datafile
> Example:
> strings dtap.couch | grep -i "226b2e6c-24b7-4336-92c7-257abf923b11"
