so Paradedb and Hydra are using same codebase or just similar approach ?

ParadeDB and Hydra are completely different. We're tackling the same problem of bringing analytics inside Postgres, but using different approaches.

ParadeDB integrates industry standards like Arrow, Parquet, DataFusion to offer columnar storage + vectorized processing. Hydra is building on top of Citus Columnar.
