Documentation

Full Documentation. Below are the basics:

Create collection

from rockydb import RockyDB

db = RockyDB(path="database/")
news = db.collection("news")

Insert document

Supported data types: str, int, float, bool and list. Will support more later.

doc_id = news.insert({
  "title": "Can store strings",
  "year": 2022,
  "people": ["lists", "are", "fine", "too"],
  "pi": 3.14,
  "real": True
})

The insert method will return a unique document _id. _id will be created if document does not contain it.

Get document

news.get(doc_id)

Delete document

news.delete(doc_id)

Query

news.find({"pi?lt": 3.14, "real": True}, limit=10)

The limit arg is optional, default is 10. Supports exact, lte, lt, gt and gte queries.
