Redis or MongoDB?

-
I do not plan to switch, but is there a documented method to migrate to MongoDB?
-
@JaredBusch No but the guys from NodeBB have a migration tool to there disposal.

I'm using mongo and its been great even with decent amount of traffic..
It depends on what your running on.. We have a prod and dev mongodb forum and a 500 slot ts3 server all on the same Ubuntu AWS micro instance!

Yes, we offer Redis to MongoDB migrations for a $50 flat fee, as it requires a bit of prep work and execution expertise
We are years down the road now, and I am wanting to migrate my D&D campaign forum to a new VM and would like to use the modern standard of mongodb instead of the legacy standard of Redis.
Is the above still all we have? A little searching turned up this year old post also.
@julian said in Drop Redis/Improve MongoDB/Support SQL?:
Yes, let it be known that if we do decide to drop support, the Redis to Mongo migration script will be immediately published
How much is this called upon? My forum is tiny, but the thought of trying to manually migrate things is still horrid.

You can use this to convert between any of the three database types.

What is best to use? Always hearing bad things about Mongodb and Redis I have been told "redis is usually used for more temporary data store.
Can't imagine what bad is being said about MongoDB. It's been amazing for us. Screaming fast, really easy to maintain, insanely stable. We are super happy with it.
We have done as much as 191 million hits in a month on MongoDB without the server even working hard.

@scottalanmiller Just don't shard MongoDB... it's where the problems arise
What issues have you seen? It should handle it well, in theory. Of course, you also shouldn't need to. The scale of the community necessary to justify sharding would be astronomic.

I migrated my forum from mongo to Postgres.
What was the impetus in going from MongoDB to PostgreSQL? MongoDB does such an amazing job.
-
@scottalanmiller im already familiar with Postgres, and monogDB isn't officially compatible with my Plesk VPS.
-
I have been working with PostgreSQL for over two months. So far not a single issue. @Ben-Lubar did an amazing job, and continues to do so - see pull request here:
https://github.com/NodeBB/NodeBB/pull/6745PostgreSQL is probably the best solution if you are hosting in AWS, since MongoDB is not available unless you can front 20K USD$ per year

Ah, makes sense. I bet the performance with a web hosting service is pretty bad, though.

I think that there must be some confusion. MongoDB is the same cost on Amazon as it is anywhere else, free. You must be thinking that using AWS requires you to not use a normal setup but some special AWS service. That's incorrect. You'd run MOngoDB the same as anywhere else, being on AWS might offer additional choices, but not fewer. There is no limitation or cost like you are thinking there. Even if you wanted a hosted MongoDB that you aren't responsible for, MongoDB's own Atlas service is VERY affordable and on AWS.
