HypoPG
A PostgreSQL extension that enables creation and testing of hypothetical indexes without actually building them.
What is HypoPG?
HypoPG is a PostgreSQL extension that enables the creation of hypothetical (virtual) indexes. It allows database administrators and developers to test whether specific indexes would improve query performance without actually creating them, thus avoiding consumption of CPU, disk, or other resources. This helps in making data-driven decisions about index optimization in a risk-free environment.
PostgreSQL database administrators and developers who need to optimize query performance by experimenting with different indexing strategies without impacting production resources.
Developers choose HypoPG because it provides a safe, resource-efficient way to test index effectiveness using standard PostgreSQL syntax, with session isolation ensuring no interference with concurrent connections. Its unique ability to hide existing indexes also allows for testing alternative indexing scenarios without modifying the database.
