+# PostgreSQL Partitioning for Zabbix
+
+This directory contains solutions for partitioning a Zabbix database running on PostgreSQL. Partitioning is essential for large Zabbix environments as it eliminates the need for the built-in Zabbix Housekeeper to aggressively delete old data row-by-row, replacing it with instant DDL operations that drop entire daily or monthly chunks.
+
+## Implementations
+
+- **[procedures](procedures/)**: The recommended Declarative (SQL-based) implementation. It uses native PostgreSQL procedures and features like `pg_cron` for entirely self-contained maintenance.
+- **[script](script/)**: External script-based management solution. (Coming soon)
