Introduction
This project implements an abstraction of objects that can have access to a variety of data stores, implementing read/write functions associated and specific to the data-sources. The classes implement functionalities against :
- Rabbitmq-server
- Couchdb-server
- Http Session : {csv,tab,pipe,sql}
- Disk{Reader|Writer} : csv, tab, pipe, sql on disk
Usage
The basic usage revolves around a factory class (to be a singleton)
import transport
from transport import factory
#
# importing a mongo reader
args = {"host":"<host>:<port>","dbname":"<database>","doc":"<doc_id>",["username":"<username>","password":"<password>"]}
mreader = factory.instance(type='mongo.MonoReader',args=args)
#
# reading a document and executing a view
#
document = mreader.read()
result = mreader.view(name)
#
# importing a couchdb reader
args = {"url":"<http://host>:<port>","dbname":"<database>","doc":"<doc_id>","username":"<username>","password":"<password>"}
creader = factory.instance(type='couch.CouchReader',args=args)
#
# Reading a document and executing a view
#
document = dreader.read()
result = couchdb.view(id='<design_doc_id>',view_name=<view_name',<key=value|keys=values>)
