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:[email protected]:5000
or when you want to push a local database to a taps server
$ taps push postgres://dbuser:dbpassword@localhost/dbname http://httpuser:[email protected]:5000
Known Issues
-
Blob data may not transfer properly, I suspect that SQLite3 is modifying some native ruby objects.
-
Foreign Keys get lost in the schema transfer
-
Large tables (>1 million rows with a large number of columns) get slower as the offset gets larger. This is due to it being inefficient having large offset values in queries.
