In plain words
Hydra is an open-source Postgres extension that adds columnar tables for analytical reporting on large datasets. It allows users to run aggregate queries on billions of rows without modifying existing code. The 1.0 release includes aggregate vectorization for faster query performance and support for spatial indexes including gin, gist, spgist, and rum indexes. Hydra is designed for developers and data analysts who need efficient analytics on Postgres without the performance degradation typically caused by long-running queries on large datasets.

Spatial indexes (gin, gist, spgist, and rum indexes) and pg_hint_plan are now enabled for performance optimization. postgres is great, but aggregates can take minutes to hours to return results on large data sets. long-running analytical queries hog database resources and degrade performance. use hydra to run much faster analytics on postgres without changing code. for testing, try the hydra free tier to create a column postgres instance on the cloud. https://dashboard.hydra.so/signup
