Here a preview to how to use relationship.
```js
GRAB User {best_friend = {name = 'Bob'}}
```
GRAB queries return a list of JSON objects with the data inside, e.g:
```
[{id:"1e170a80-84c9-429a-be25-ab4657894653", name: "Gwendolyn Ray", age: 70, email: "austin92@example.org", scores: [ 77 ], friends: [], }, ]

### Question. How de fuck I am parsing files to get relationships ?
I dont want to parse them more than 3, best 2, perfect 1
The issue is that, I could do optimization here but I dont have enough yet. I need to start doing something that work then I will see.
So I parse:
- All files that
Now this is where the Radix tree come into place. Because if I get to find one UUID in 50000 files, and I parse all of them, this is meh.
So I need a Radix tree to be able to find all file to parse.
1. Get the list of UUID that need to be parse.
For example if I do "GRAB User [mom] {name = 'Bob'}". I parse one time the file to get all UUID of User that represent mom; the parse that is already done and need to be done. So if I found 3 Bob's mom UUID
2. Then I create a map of Bob's UUID as keys and a Str as value. The Str is the JSON string of the mom. For that I need to parse the file again and write using additional_data
### Radix tree
Ok so new problem. Given a list of UUID, I need a way to find all file index to parse.
And even better if I can get the number of UUID per files, so I can stop parsing them early.
Happy to annonce the v0.2 of my database. New feature include:
- Relationship
- Huge performance increase with multi threading
- Date, time and datetime type
- Linked query
- Compressed binary files
- Logs
All core features of the query language is working, v0.3 will focus on adding things around ot, including:

Query optimization for later:
- If a filter use id to find something, to stop after find it, as I know there is no other struct with the same id

You need to specify all members when adding an entity (default values are coming soon).
