MongoDB is the recommended data store.
For development I use redis because it is just easier for me to use (e.g. zrange sortedSet 0 -1 vs db.objects.find({ _key: "sortedSet" }).pretty();)
All three are supported by the NodeBB team 😄
Elasticsearch as a database
-
Hi, I have seen that NodeBB has a Database Abstraction Layer (DBAL), I wonder if you guys have ever thought of implementing Elasticsearch a DB, if not... I'm doing it!
-
It works, I have used it to store documents as a NoSQL db, it's a Document search engine and in fact lucene is extremely good as a key/value storage. I have never missed documents in Elasticsearch... in Mongo... well... so many times to never use it again...
-
Minor FYI....Elasticsearch has made a strong stand that they are not a database. There are certain levels of consistency and reliability to qualify as a database that they have said they cannot support. But if your data isn't critical, and you don't mind a noticeable a delay between when you write a document and when it available for reading, then that's fine.
