volttron-lib-sql-historian 0.1.1a5

None

Generic SQL Historian library that can be used to implement a historian agent with a relational database backend. This library cannot be installed as a VOLTTRON agent as is. Only a concrete database implementation package such as sqlite-historian that depends on this library can be installed as a VOLTTRON agent.

Requirements

• Python >= 3.8

Installation

This library can be installed using pip install volttron-lib-sql-historian. However, this is not necessary. Any historian agent that uses this library will automatically install it as part of its installation. For example, installing SQLiteHistorian will automatically install volttron-lib-sql-historian

Development

Please see the following for contributing guidelines contributing.

Please see the following helpful guide about developing modular VOLTTRON agents

To create a new relational database based historian by extending this library, subclass DBDriver. The subclass should be in a module historian.<database_type>.<database_type>functs.py for it to be dynamically loaded by the base DBDriver. Please refer to SQLiteHistorian as an example
