Postgres on NVMe: performance and the convergence of transactions and analytics
AI summary
Ổ cứng NVMe địa phương cải thiện đáng kể hiệu suất transaction trong Postgres, đạt tới 150,000 transaction mỗi giây trong thử nghiệm. Sự cải thiện này đến từ tốc độ đọc ghi nhanh hơn nhiều so với SSD thông thường, giảm độ trễ từ hàng chục mili giây xuống còn dưới 1 mili giết. Tuy nhiên, khi quy mô workload tăng lên, Postgres vẫn bộc lộ hạn chế trong xử lý phân tích so với ClickHouse, chuyên biệt cho analytics workloads. Điều này cho thấy các hệ thống cần kết hợp cả hai công nghệ: Postgres cho transaction và ClickHouse cho analytics.
