These can be useful in certain scenarios, although some purists suggest that it's better to avoid "relational thinking" and aim for a purely key-value approach, in order to better understand MongoDB. If you run ps -xa grep mongod and you don't see a -dbpath which explicitly tells mongod to look at that parameter for the db location and you don't have a dbpath in your nf, then the default location will be: /data/db/ and you should look there. In MongoDB, use GridFS for storing files larger than 16 MB. MongoDB also allows relations between collections. mongod defaults the database location to /data/db/. Some people like to impose a schema using one of the many available object document mappers (ODMs), either when saving or later on for query/retrieval. compound keys will not work for that case. This is particularly the case if you intend to employ map-reduce, e.g. But then how do you retrieve documents and what do you want to do with them? It helps to have a good idea of document structure, which keys to index, which keys to query on and so on. services/ exports FileUploadService that uses angular/fire‘s AngularFireStorage & AngularFireDatabase to interact with Firebase. GridFS allows you to store and retrieve files, which includes ones exceeding the BSON-document size limit of 16 MB. The temptation with MongoDB is simply to "stuff and forget" - any data that can be parsed into a hash-like structure is easy to save. environment.ts configures information to connect with Firebase Project. MongoDB has a driver specification to upload and retrieve files from it called GridFS. It uses two database collections, one to store the metadata for the file, and another to store the contents of the file. TLS is a cryptographic protocol that provides secure communications on top of an existing application protocol, like HTTP or MySQL. As Brad suggested, you'll need GridFS to store larger objects.Īs with any database, it's good to think about design before you start. This constrains your document design, so you need to think about what goes into a document. Longer answer: as discussed above, the main consideration is the 4 MB size limit for documents. Short answer is "yes" you can store anything you like in MongoDB, it's schema-free.
