How We Solved a Storage Problem in PostgreSQL Without Adding a Single Byte of Storage

Read Original

The article details a real-world PostgreSQL performance problem where nightly ETL deduplication queries consumed excessive temporary disk space due to large sort operations. It explains the diagnosis using execution plans, identifies the `work_mem` parameter's role, and presents a solution: hashing the large binary sort key to drastically reduce its size, thereby eliminating the need for extra storage or configuration changes.
