Lift

MongoDB GridFS supports storage of arbitrary length files using a chunked storage approach, see here for more details: http://www.mongodb.org/display/DOCS/GridFS

Assuming you’ve defined a default MongoDB connection in your Lift app, you can store a file using GridFS:

import com.mongodb.gridfs._
import net.liftweb.mongodb._

MongoDB.use(DefaultMongoIdentifier) { db =>
  val fs = new GridFS(db)
  val inputFile = fs.createFile(new java.io.File("/path/to/myfile"))
  inputFile.setContentType("text/plain")
  inputFile.setFilename("myfile")
  inputFile.save
}

GridFS files can be retrieved in a number of ways, see: http://api.mongodb.org/java/current/com/mongodb/gridfs/GridFS.html

For example by filename:

 MongoDB.use(DefaultMongoIdentifier) { db =>
  val fs = new GridFS(db)
  val foundFile = fs.findOne("myfile")
  foundFile.writeTo("/path/to/myfoundfile")
}
