Here is the code under consideration (from redis-stream module) which I am
considering using.
Writing to the underlying stream creates a new connection. It seems like
this would be expensive, but that is what I am asking...whether it is or
not. One might say to keep the stream open with {end:false} but that isn't
suitable often since the args change to consume the wrapping code. I think
I would have cached the connection the first time, but I am not sure if
that is important or not in node using the Net lib.
Redis.prototype.stream = function (cmd, key, curry /* moar? */) {
var curry = Array.prototype.slice.call(arguments)
, clip = 1
, _redis = this.createConnection()
, stream = es.pipe(
es.pipe(
es.map(function (data, fn) {
var elems = [].concat(stream.curry)
, str = data+''
if (!str.length) return fn()
else elems.push(str)
// console.log('write', str)
return Redis.parse(elems, fn)
}),
_redis
),
es.pipe(
es.split('\r\n'),
es.map(replyParser)
)
)
;
stream.curry = curry
stream.redis = _redis
stream.redis.write(Redis.parse([ 'select', this.db ]))
return stream
