Subject RE: CouchDB: Remote IP Address in Map Function
Date Thu, 14 Nov 2013 04:47:49 GMT
And on that note... Maps aren't like SQL queries. They're designed to
run against the data to produce indexable data. Think about it like a
SQL index that you are building. You obviously can't include the remote
user's information in a SQL index because that is built when things
change. The same is true for CouchDB. There is no reason why map
building has to happen when a user makes a query, it's just convenient
for CouchDB to do so.

If you want to index the user's remote address, create a document and
toss it in there. Or update an existing one. This mechanism becomes a
little weird if you're making a CouchApp. From: Jens Alfke
