Left fold reduction / pluggable view reduction

Hi, I've been eyeing[1][2] CouchDB as a viable event store for event sourcing[3] for a while. In many cases it's a very good fit and being to replicate view projections would be awesome. My main concern is that CouchDB view reduce operations aren't linear. That is, they aren't strictly a left fol

Re: Force caching CouchDb responses

Hi, Would you care to share with us which caching reverse proxy you are using? If you are using nginx you could probably use http://wiki.nginx.org/HttpProxyModule#proxy_cache. That said, as long as your reverse proxy support "Etag"s you should be fine, since that's what CouchDB supports. Cheers,

Data usage and compaction status

Hi, When I look at `/mydb`[1] I am given a lot of statistics. Among them is `data_size`. However, when I look in the documentation[1] I can't find it. Is it missing or has it been removed? What value does it show? I am running CouchDB 1.5.0. Two related questions: 1. The `disk_size` measureme

Ordered view reduce

Hi, I've been playing around with CouchDB for event sourcing[1] (terminology from DDD and CQRS). Basically I have a series of ordered events persisted to Couch and I've been creating simple projections basic these. The ID of a new event will be strictly greater that all previous events for its agg

Hi again, The documentation hereclaims that there is a "filter" parameter that can be supplied to activate filtered replication from one database to another. I can't seem to find it in the official replication documentation

CouchDB sharding orchestration

Hey couchers, For the past week, I've been playing with the thought of implementing a sharding orchestrator for CouchDB instances. My use case is that I have a lot of data/documents that can't be stored on a single machine and I'd like to be able to query the data with fairly low latencies. Oh, th

BigCouch

Hi, I think I have a use case that would fit BigCouch quite well. This brings me to three questions: - When is the BigCouch merge expected to be released? Maybe I should focus on getting that one working if it's near in time. - If I choose to go with the original BigCouch, will it be eas

Re: crawl webpages into couchdb

Hi Affi, Your question is very unspecific. We have no idea what kind of information you are going to crawl from websites and you need to decide that for yourself (or find a forum that's more specific to crawling). If you tell us what information you have, and how you would like to query it we migh

Changes API - purged?

Hi, I have a use case where I'd like to build up an external state by following the changes of a database. Obviously, the /db/_changes will be a great source to start for this. My question is, can I always be sure that simply following /db/_changes from seqnum=0 will bring me to a consistent state

Hi Michael, Using the command "sudo netstat -nlp" you can see which ports and interfaces your listening programs are bound to. CouchDB will show up as the program "beam". Hope this helps, Jens On 25 apr 2011, at 05:19, Michael Heuberger wrote: > > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA

Debian package

Hi, I am considering deploying CouchDB on a Debian system. I have noticed that the Debian package for CouchDB is rather old [1]. The latest package version contains CouchDB 0.11.0 and currently there is a security patch that is still to be added to the package[2]. My question is really, would you
