stream audio/video files from gridFS on the browser

问题 I have been trying to read an audio file from mongoDB which i have stored using GridFS. I could download the file in the system and play from it but I wanted to stream those audio/video files from the DB itself and play it in the browser. Is there anyway to do that without downloading the file to the system? Any help would be good. 回答1: The PHP GridFS support has a MongoGridFSFile::getResource() function that allows you to get the stream as a resource - which doesn't load the whole file in

问题 Please look at the following image, from http://mongoexplorer.com/: I've been trying to work through GridFS, referencing https://github.com/jamescarr/nodejs-mongodb-streaming. The files I uploaded, come back nicely and the stream that comes back via the following get function looks right. var gridfs = (function () { function gridfs() { } gridfs.get = function (id, fn) { var db, store; db = mongoose.connection.db; id = new ObjectID(id); store = new GridStore(db, id, "r", { root: "fs" });

How do you put the close() in the writeBuffer callback? This question relates to: Problem with MongoDB GridFS Saving Files with Node.JS A simple example is https://github.com/mongodb/node-mongodb-native/blob/master/test/gridstore/grid_store_test.js#L97 Also check the docs for changes in behavior, writeBuffer was removed so just use write. http://mongodb.github.com/node-mongodb-native/ 来源： https://stackoverflow.com/questions/10092282/saving-files-to-mongodb-gridfs-with-node-js

Configure GridFS Chunksize in MongoDB

问题 I'm currently investigating to use MongoDB for storing E-Mail data. As E-Mails may become rather big in size (say 10 megs). I believe that GridFS would be a good fit for this. What scares me a bit tough is, that the docs are not very clear about the shard size within gridFS. From what I understand is, that the shard size in gridFS is not equal to the normal shard size but defaults to 256kb. Which sounds to me like a big waste of space, as many e-mails will not exceed 50kb in size. Is there a
