pyhera

Introduction

pyhera is a lightweight in-memory database management module written in python. An optimized NoSQL database which is fast. Data are stored in JSON format (key-value) thus created databases can be analyzed by other applications in different platforms.

Features

  • Ease of use.No complicated syntax
  • Fast because ofmultithreading implementation
  • It's secure.Database is not modifiable from outside
  • Reliable.pyhera automatically takes back-up

Easy Installition

pip install pyhera

Quick start

A very basic instance:

importpyhera# Import pyhera moduleh=pyhera.Pool('mydb')# Create database objecth.set('foo','bar')result=h.get('foo')print(result)# Print 'bar'

To use it in temp mode:

importpyherat=pyhera.Pool('mydb',temp=True)# Create temp database objecth.lmls('foo', [1,2,3])# Won't be saved in database fileresult=h.lret('foo')# Only stored in memoryprint(result)# Print '[1, 2, 3]'

Code samples

To compare X and pyhera:

#X (a key-value series database)r=connection()r.dset('foo','bar1',1)r.dset('foo','bar2',2)r.dset('foo','bar3',3)d1=r.dget('foo','bar1')d2=r.dget('foo','bar2')d3=r.dget('foo','bar3')print(d1+d2+d3)# 6#pyhera (Above method is also possible in pyhera)h=pyhera.Pool('mydb')h.dmls('foo', {'bar1':1,'bar2':2,'bar3':3})d,sum=h.dmlg('foo'),0fork,vind.items():sum+=vprint(sum)# 6

Documentation

Documentation of pyhera project will be released as soon as possible.
