libgs.database.PassDb

class libgs.database.PassDb(db='sqlite:///libgs.db', binary_fmt='b64', disk_threshold=1000, disk_path='.', **kwargs)

Interface class to Pass Information Database.

The Pass Information Database is a key/value type database that stores arbitrary data about a pass (pass information). Each key/value pair is associated with the pass id and module from which it was added for easy search.

It sets up a table with the following columns

key	The pass information key
value	The pass information value
pass_id	The pass id associated with the current monitor entry
module	The module that requested the data to be added to the database

Additionally each row is assigned a primary key and a timestamp
