A Path Hint is a predefined path that is provided to B-tree operations. It’s just a hint that says, “Hey B-tree, instead of starting your binary search with the middle index, start with what I provide you. My path may be wrong, and if so please provide me with the correct path so I get it right the next time.”
|
||||
|
||||
I’ve found using path hints can lead to a little performance increase of 150% - 300%. This is because in real-world cases the items that I’m working with are usually nearby each other in the tree.

## Using a Path Hint
|
||||
|
||||
All of the functions that take in a path hint argument mutate the path hint argument.
|
||||
|
||||
For single-threaded programs, it’s possible to use one shared path hint per B-tree for the life of the program.
|
||||
For multi-threaded programs, I find it best to use one path hint per B-tree , per thread.
|
||||
For server-client programs, one path hint per B-tree, per client should suffice.

### Literals
|
||||
|
||||
Starting with v1.12.0, GJSON added support of json literals, which provides a way for constructing static blocks of json. This is can be particularly useful when constructing a new json document using [multipaths](#multipaths).
|
||||
|
||||
A json literal begins with the '!' declaration character.
|
||||
|
||||
For example, using the given multipath:
|
||||
|
||||
```
|
||||
{name.first,age,"company":!"Happysoft","employed":!true}
|
||||
```
|
||||
|
||||
Here we selected the first name and age. Then add two new fields, "company" and "employed".
|
||||
|
||||
This results in
|
||||
|
||||
```json
|
||||
{"first":"Tom","age":37,"company":"Happysoft","employed":true}
