TableManager

class felis.tap_schema.TableManager(engine=None, initialize_database=False, schema_name=None, table_name_postfix='')

Bases: object

Manage creation of TAP_SCHEMA tables.

Parameters:

• engine (Engine | None, default: None) – The SQLAlchemy engine for reflecting the TAP_SCHEMA tables from an existing database. If initialize_database is True, this engine will be used to create the tables. If None, an in-memory SQLite database will be used.

• schema_name (str | None, default: None) – The name of the schema to use for the TAP_SCHEMA tables. If None, the standard name of ‘TAP_SCHEMA’ will be used.

• table_name_postfix (str, default: '') – A string which will be appended to each of the standard table names. This needs to be used in a way such that the resultant table names map to tables existing tables within a TAP_SCHEMA database.

• initialize_database (bool, default: False)
