LSDB#
LSDB (Large Survey DataBase) is a python framework that enables simple, fast spatial analysis of extremely large astronomical catalogs (e.g. querying and crossmatching ~10⁹ sources). It aims to address large-scale data processing challenges, in particular those brought up by LSST.
Built on top of Dask to efficiently scale and parallelize operations across multiple distributed workers, it uses the HATS data format to efficiently perform spatial operations.
