ASTROIDE is an open source software, distributed under GPL V2 Licence. It was initiated by the DAVID Lab and co-funded by the UVSQ and the CNES. ASTROIDE achieves scalability and efficiency by combining the benefits of distributed processing using Spark with the relevance of an astronomical query optimizer.
ADQL and DataFrame
ASTROIDE supports the data access using DataFrame and the most common astronomical query language ADQL.
HEALPix Partitioning
ASTROIDE combines data partitioning with HEALPix indexing technique.
Query Optimization
ASTROIDE extends the Spark optimizer and exploits partition pruning for astronomical operators.
