Flask-kdb 1.0.0

kdb+ connections within a Flask application.

Flask & KDB (qPython3 | finos)

A repo designed to how to connect your Flask app to a q/KDB+ process using the finos python/kdb library - qPython3

Install

pip install Flask-kdb

Configuration

Thisis just a very basic showcase. Currently these envirnoment variables are used:

KDB_HOST
KDB_PORT

Usage

Import the class FlaskKDB and initialize using by using the constructor:

from flask import Flask
from flask_kdb import FlaskKDB

app = Flask(__name__)
app.config['KDB_HOST'] = 'localhost'
app.config['KDB_PORT'] = 5000
kdb = FlaskKDB(app)

or delayed initialisation (via init_app):

app = Flask(__name__)
app.config['KDB_HOST'] = 'localhost'
app.config['KDB_PORT'] = 5000

kdb = FlaskKDB()
kdb.init_app(app)

The first method is uses a persistant DB connection object that can be imported when required. I implemented this from this answer from toppatopvt on StackOverflow
