Taps – simple database import/export app

A simple database agnostic import/export app to transfer data to/from a remote database.

Usage: Server

Here's how you start a taps server

$ taps server postgres://localdbuser:localdbpass@localhost/dbname httpuser httppassword

You can also specify an encoding in the database url

$ taps server mysql://localdbuser:localdbpass@localhost/dbname?encoding=latin1 httpuser httppassword

Usage: Client

When you want to pull down a database from a taps server

$ taps pull postgres://dbuser:dbpassword@localhost/dbname http://httpuser:httppassword@example.com:5000

or when you want to push a local database to a taps server

$ taps push postgres://dbuser:dbpassword@localhost/dbname http://httpuser:httppassword@example.com:5000

or when you want to transfer a list of tables

$ taps push postgres://dbuser:dbpassword@localhost/dbname http://httpuser:httppassword@example.com:5000 --tables logs,tags

or when you want to transfer tables that start with a word

$ taps push postgres://dbuser:dbpassword@localhost/dbname http://httpuser:httppassword@example.com:5000 --filter '^log_'

Known Issues

• Foreign key constraints get lost in the schema transfer

• Tables without primary keys will be incredibly slow to transfer. This is due to it being inefficient having large offset values in queries.

• Multiple schemas are currently not supported
