gridfs

I am currently working on a website where, roughly 40 million documents and images should be served to it's users. I need suggestions on which method is the most suitable for storing content with subject to these requirements. System should be highly available, scale-able and durable. Files have to be stored permanently and users should be able to modify them. Due to client restrictions, 3rd party object storage providers such as Amazon S3 and CDNs are not suitable. File size of content can vary from 1 MB to 30 MB. (However about 90% of the files would be less than 2 MB) Content retrieval

I am wondering what is the maximum file size if someone wants to store a file using the GridFS? I can't find any information so any help would be appreciated. Infinity basically, or a more exact number would be how much your working set allows. The GridFS standard implemented within drivers will split files up into smaller chunks and store them in a fs.chunks collection irrespective of how big the file is. 来源： https://stackoverflow.com/questions/16604875/mongodb-maximum-file-size-using-gridfs

I am using gridfs-stream https://github.com/aheckmann/gridfs-stream & currently i am on displaying image from gridFS. When reading data it gives me following output. When i append this data to <img src="data:image/jpeg;base64,(data)"> , the image doesn't show. gfs // create a read stream from gfs... .createReadStream({ filename: 'error1.png' }) // and pipe it to Express' response .pipe(res); Output res :- Edited :- I tried this :- img.src = 'data:image/jpeg;base64,' + btoa(res); Output rendered is :- <img src="data:image/jpeg;base64,W29iamVjdCBPYmplY3Rd"> No image shown. I use file stream

I am creating a single page application using JavaScript(JQuery) and need to store large video files which size exceed 16Mb. I found that need to use GridFS supporting large files. As I am the new one to MongoDB I am not sure how to use GridFS. There are some good tutorials on creating applications using Node.js, MongoDB and Express but cant find any describing how to use GridFS with MongoDB (not mongoose), Express and Node.js. I managed to put up stuff for uploading files in the BSON-document size limit of 16MB. This is what I have: var express = require('express'); var path = require('path')

I need to download a resume from GridFS, below is the code ive written to do it, but this seems to not give me a physical file for download, this is used to reading the contents. How can i download the file? exports.getFileById = function(req, res){ var conn = mongoose.connection; var gfs = Grid(conn.db, mongoose.mongo); var id = req.params.ID; gfs.exist({_id: id,root: 'resume'}, function (err, found) { if (err) return handleError(err); if (!found) return res.send('Error on the database looking for the file.'); gfs.createReadStream({_id: id,root: 'resume'}).pipe(res); }); }; Hope this helps!

I have a nodejs app that uses Mongo and GridFS to store images. I'm trying to display these images to the browser via Node.js (using express framework). I'm currently using: res.writeHead(200, {'Content-Type': 'image/jpeg' }); res.end(imageStore.currentChunk.data.buffer, 'binary'); imageStore is a the gridStore object after creating a new GridStore and calling gridStore.open(...) var gridStore = new GridStore(self.collection.db, doc._id, doc.filename, 'r', { chunk_size: doc.chunkSize }); gridStore.open(callback); I'm sure this isn't the right way, it displays a broken image. Any suggestions?
