Let me see if I can draw pretty things. Given keys: 1 2 # a 2 2 3 # b 4 5 # c 5 5 # d 6 I've noted four rows that we might be interested in in referencing. So we have basically four ranges as far as I can tell. (a->c, a->d, b->c, b->d) and the inclusive ends will determine the various ranges. So AFAICT, inclusiveness means "include rows equal to the key". So by default, we run inclusive_start, non_inclusive_end. inclusive_end then came around so that we could include keys equal to the end key which means we don't have to construct a key one greater than our range of interest. IIUC, then what we're really trying to do is create a inclusive_end=false option which is what's being proposed. Is that in agreement with what everyone else is thinking? Also, +1 randall's inclusive=start|end|both option. > implement inclusive_start view option > ------------------------------------- > > Key: COUCHDB-1125 > URL: https://issues.apache.org/jira/browse/COUCHDB-1125 > Project: CouchDB > Issue Type: Bug > Affects Versions: 1.2 > Reporter: Jan Lehnardt > Priority: Minor > Attachments: inclusive_start.patch > > > From COUCHDB-194: > I suggest to generalize to left or/and right opened range. > Because, to select a left opened range of keys, we have to use a tip. > Exemple : > keys = [1, 2, 3, 4, 5] > to select where 2 We have to do : startkey=2&skip=1 > But : > If keys are no unique, the "skip" tip no more works. > Ex: keys = [1, 2, 2, 3, 4, 5] > The request startkey=2&skip=1 doesn't work because a "2" key is returned. > (ps: non unique keys can be a wanted result) -- This message is automatically generated by JIRA.
