Hi all,
I'm beginning to get familiar with the administrative functions of couchdb 0.11
and had a question about rev limits and compaction. In my testing it seems
rev limits are being reset to the default 1000 after I run _compact, even
though the wiki states otherwise:
"_revs_limit defines a upper bound of document revisions which CouchDB keeps
track of, even after Compaction"
http://wiki.apache.org/couchdb/HTTP_database_API#Accessing_Database-specific_options
For instance if I run the following series of curl commands that create a new
db,set the revs limit, get the revs limit, run compact, and get the revs limit
again I see that the revs limit gets reset.
Searching jira for "_revs_limit" doesn't return any results, so if anyone could
shed any light on the subject for me I would greatly appreciate it.
Thank you,
Erick Johnson
