Hi Simon,
Static arguments can be passed to MapReduce queries using the "arg"
property. Here is an example query that runs over all the keys in the bucket
"bucket":
{
"inputs": "bucket",
"query": [
{
"map": {
"language": "javascript",
"source": "function(value, keyData, arg) { return [arg]; }",
"keep": true,
"arg": "static data"
}
}
]
}
