gluex-ccdb (Python)

Python bindings around the gluex-ccdb Rust crate. They expose lightweight wrappers for CCDB directories, tables, and columnar payloads without compromising type information.

Installation

uv pip install gluex-ccdb

Example

import gluex_ccdb as ccdb

# Uses CCDB_CONNECTION by default; pass a path to override.
client = ccdb.CCDB()
tables = client.fetch("/PHOTON_BEAM/pair_spectrometer/lumi/trig_live", runs=[55_000, 55_005])

for run, dataset in tables.items():
    print(f"columns: {dataset.column_names()}")
    livetime = float(dataset.column(1).row(0))
    print(f"run {run}: livetime = {livetime:.3f}")
