I like your 53 mins intros, but that said you cover and reach all the important parts. I wonder what will be deep dive session how long will that video be.

@dafyre said in PATH Error with TimeScaleDB-Tune on Fedora 30:

then why are you even using it?

Capacity Planning, for example.

So, circling back. How is the backup project going?

@scottalanmiller said in MongoDB Major Change to Licensing:

if you are a SaaS vendor looking at building software that uses MongoDB somewhere, you'd better get a lawyer looking over this license and how it applies to you.

This is becoming a bigger issue as the biggest SaaS vendors hide behind this clause more and more with incredibly proprietary forks. They offer very little to no actual core development or contribution and it goes against the previous method of GPL code getting funding.

It annoys me, as the legal headaches of contributing internal only use code back will block some companies from using OSS, but I see it both ways.

The startups who are doing a lot of the core housekeeping of NOSQL platforms are learning they can't find a business model. This is getting messier and messier.

Partially because there are just too any vendors involved.

What's amazing, though, is that a move like this took a customer who was very into MongoDB and using it in projects and was literally working with MongoDB's own hosted product and now looking to avoid it like the plague.

So at least in this one case, they are likely losing hosted product from this. And gaining nothing. I imagine a lot of customers going through this same process.

@scottalanmiller okay, they totally fucked this up.

Yeah, this is some weird stuff.

So I don't believe it handles snapshots yet, but it still looks like a pretty useful tool that I have been meaning to try out for people who don't want to manage through the API.

@scottalanmiller said in Remove Duplicate Entries from MongDB Collection:

You can add an index as well, to avoid having duplicates occur in the future:

db.myCollection.createIndex({"my_field_to_be_unique":1},{unique:true})

Good idea.

For more detail, showing the UIDs of each of the duplicates in question, try this little extension:

db.myCollection.aggregate([ {$group: { _id: "$field_to_search", "dups": { "$push": "$_id" }, count: { $sum: 1}}}, {$match: { count: { $gt: 1 }}}])

Gotta love that MongoDB :)

@scottalanmiller said in Why Does Everyone Still Focus on Relational Databases?:

I just built out a NoSQL ElasticSearch three node cluster in the lab. Whoo!

The perfect DB setup for storing a hit counter for the number of times I've watched Tombstone!

@scottalanmiller said in Installing MongoDB 3.2 on CentOS 7:

Just tested and deployed to CentOS 7.2 on Linode.

This failed me, so I went to the mongo docs and the baseurl contains the variable $releasever.

using that results in redhat//mongodb in the file, which is why I assume you hard coded that bit.

Escaping the $ fixes it.
