Kongodb

Kongodb is Hybrid Row-and-Document Oriented datastore leveraging SQL/RDBMS database: SQLite, MySQL, MariaDB, Postgresql

Kongodb is both RDMBS + Document Oriented together.

It supports, regular SQL query along with Document Oriented and Key Value store.

Engine:

• SQLite
• Mariadb
• PostgreSQL
• MySQL

Install

pip install kongodb

Usage

from kongodb import kongodb

# Open the db
db = kongodb("./my.db") 

# Select a collection 
# Collection will be created automatically
collection = db.collection("test")

# Get total items
print(len(collection))

# Add an item. It returns kongodb#Item
item = collection.add({
  "name": "Kongo",
  "type": "DB",
  "version": "1.0.0"
})

# Retrieve item by _id
_id = "9c5e5fbd05544700995c5fa3ca3ef214"
item = collection.get(_id)

# Access properties

item.get("name") # -> fun 
item.get("type") # -> DB
all_item_data = dict(item)

# Update a field
item.set("version", "1.0.1")

# or advance atomic update
item.update({
  "version": "1.0.1",
  "download:$inc": True,
  "ips:$xadd": "0.0.0.0"
})
#
item.get("version") # -> 1.0.1
item.get("download") # -> 1 or last value + 1
item.get("ips") # -> ["0.0.0.0"]

# Delete item
item.delete()

# Search
for item in collection.find():
  print(item.get("name"))

Database

kongodb

#collection

To select a collection in the database

from kongodb import kongodb 

db = kongodb()

users = fun.collection("users")

# all users

all_users = users.find_all()

#Collection

List all the collections in the database

from kongodb import kongodb 

db = kongodb()

users = fun.collection("users")

ColumnTypes For Index:

Type	Column	SQlite	MariaDB	PostgreSQL
Integer	IntegerType	INT	INTEGER	INT
String	StringType	VARCHAR(n)	VARCHAR(n)	VARCHAR(n)
Bool	BoolType	INT(1)	TINYINT(1)	BOOLEAN
Datetime	DatetimeType	TIMESTAMP	DATETIME	TIMESTAMP
Numeric	NumericType	FLOAT	DOUBLE PRECISION	DOUBLE PRECISION

*n = the max number for the char

ColumnType

  types.[columtype](
      name:str,  # str: name of the field
      length:int, # int: length of the type if available 
      index:bool, # bool: to index the field
      unique:bool, # bool: to index and make field unique  
      default:Any # Any: any data to set as default
  )
ie: 

Example

types.StringType(
  name="myFieldName",
  length=125,
  index=True,
  unique=True,
  default="Hello"
)

Add Columns

from kongodb import kongodb, types

COLUMNS = [
  types.IntegerType('count', index=True, default=0),
  types.BoolType('is_active', default=True),
  types.Datetime('created_at', default="NOW()"),
  types.String('full_name'),
  types.NumericType('amount', default=0.00)
]

db = kongodb("sqlite://")

collection = db.collection('test', columns=COLUMNS)
