Saying it's harder because of using M/R in secondary indexes is subjective. Most people will see maps as a way to match documents and emit values they need to query later / keys. Which at the end especially for javascript is user give a lot of flexibility. (some should also ask himself why mpngodb added this feature later). M/R chaining: there are some nodejs project that does that. Waiting for this feature in couchdb that will probably come soon in a way or another. no in/place update. Well such things could be done using _update functions if you really need it while still having an append-only database. If you really care about your data you don't want to update in place except in a cache database maybe. no sharding/scale: true for now. But actually the code coming fonm cloudant.con is actually in the process to be merged. Popularity. true . This is true for all db backed with a lot of money anyway: http://db-engines.com/en/ranking Poor support I don't see why not using Github as an authority means poor user support. You can use Jira, you can use the mailing-lists open to every one. You have an open documentation that you can patch. And support of PR from github has been considerably improved. Couchdb is also backed by one of the oldest organisation in the world. About the "high-availability", "scalability", "high-load" , you're saying they are not here. It all depends what you mean when using these terms. It all depends on your usage. also. A lot of usages around will contradict your feeling. - benoit > On Wednesday, August 28, 2013 5:35:40 PM UTC+4, Dylan Hassinger wrote: > >> Hi everybody - I am a Node newb building my first app, and trying to >> figure out which database system to use.
