A tiny text-based database.

GitHub tag (latest by date) GitHub issues GitHub pull requests License

dbetto is a lightweight Python library that enables seamless access and management of text-based databases (JSON/YAML) scattered across your filesystem. Whether you're handling nested data structures or querying data by validity periods, dbetto simplifies it all with an intuitive interface.

The project was originally developed to efficiently manage metadata for the LEGEND experiment.

Key Features

Access JSON/YAML files like a Python dictionary
Attribute-style access with tab-completion for rapid query
Time-sensitive data querying with validity rules
Data remapping and grouping functionalities

Showcase

Install from PyPI:

pip install dbetto

Access data arbitrarily structured as JSON or YAML files:

>>> from dbetto import TextDB
>>> db = TextDB("/path/to/data/folder")
>>> db["dir1"]["file1.json"]["value"]
1
>>> db.dir1.file1.value
1

Query data valid on a given time period:

>>> from datetime import datetime
>>> db.on(datetime(2023, 1, 10, 9, 53, 0)).value
3

Map data according to alternative keys:

>>> chmap = db["detectors.yaml"]
>>> chmap.V05266A
{'name': 'V05266A',
 'location': {'string': 1, 'position': 4},
 'daq': {'crate': 0,
  'rawid': 1104003,
 ...
>>> chmap.map("daq.rawid")[1104003]
{'name': 'V05266A',
 'location': {'string': 1, 'position': 4},
 'daq': {'crate': 0,
  'rawid': 1104003}}
>>> grouped = chmap.group("electronics.cc4.id")["C3"]
>>> grouped.map("name").keys()
dict_keys(['V02160A', 'V02160B', 'V05261B', 'V05266A', 'V05266B', 'V05268B', 'V05612A'])
