## Description

Pigsty is a full-stack orchestration suite for deploying, monitoring, and managing high-availability PostgreSQL clusters and their supporting infrastructure. It functions as a cluster management platform and high-availability suite that automates failover, manages virtual IPs, and ensures data consistency through distributed consensus.

The project distinguishes itself by providing a comprehensive database infrastructure-as-code framework and a dedicated observability stack. It incorporates a backup and recovery manager supporting point-in-time recovery via S3-compatible object storage, alongside compatibility layers that allow PostgreSQL to emulate the wire protocols of Oracle, MySQL, and MongoDB.

Its broader capabilities cover database security hardening through role-based access control and traffic encryption, performance tuning for specific workloads, and advanced traffic management via connection pooling and load balancing. The platform also supports the deployment of integrated components such as Redis, Kafka, and vector search for retrieval-augmented generation tasks.

The system uses idempotent playbooks for infrastructure automation and provides a graphical user interface for cluster administration and web-based database exploration.
