Unless there are conflicts, it shouldn’t be getting longer than the RevsLimit configured for the database. Did you edit your configuration to set a lower RevsLimit? (And note that the change doesn’t apply to a document until the next time it’s saved.) > If i trim the revs, parents and deleted arrays at the same time, leaving the > last 20 items, do this will trim my history tree?. No! This will just break the revision tree and cause Go panics when accessing the document. Please read the comments on the revTreeList struct in revtree.go. "Ordering in the arrays doesn't matter.” (It’s random, determined only by the order in which the hash table is enumerated.) It is possible to edit the JSON to trim old revisions, but it will take a good knowledge of the schema it’s written in. Hopefully the revTreeList struct and the MarshalJSON method have enough info to figure out the details. I don’t want to tell you not to hack on this :) but if you do so, you’re entering the territory of a SG developer. It would be great if you found bugs or inefficiencies in managing the rev tree, and even better if you sent us fixes, but please don’t do this to any database you plan to use in production. (Or if you do, don’t ask us for help with resulting problems because they’re going to be impossible for us to troubleshoot without understanding the changes you’ve made to the code…) —Jens -- You received this message because you are subscribed to the Google Groups "Couchbase Mobile" group.
