Feel free to send in more questions as they come :-)
Okay, I have another one :)
How are views with a reduce function affected by deletes and updates?
Given the example (<http://wiki.apache.org/couchdb/HttpViewApi>) of:
"total_purchases": {
"map": "function(doc) { if (doc.Type == 'purchase')
emit(doc.Customer, doc.Amount) }",
"reduce": "function(keys, values) { return sum(values) }"
}
How would that total be updated if something were deleted or updated?
Does the sum() function have to be evaluated over doc.Amount of
*every* doc on every update?
