একটি অনুসন্ধান কার্যকারিতার জন্য আমি এমন একটি ভিউ ব্যবহার করছি যাতে আমার সন্ধান করা দরকার এমন সমস্ত টেবিলের রেকর্ড রয়েছে। দৃশ্যটির প্রায় 20 মিলিয়ন রেকর্ড রয়েছে। এই মতামতের বিরুদ্ধে অনুসন্ধানগুলি খুব বেশি সময় নিচ্ছে।
এই দৃশ্যের কর্মক্ষমতা উন্নত করার জন্য আমার কোথায় নজর দেওয়া উচিত?
দেখার জন্য রুক্ষ সংজ্ঞাটি নীচে is এটিতে তেরটি সারণী এবং ত্রিশটি ক্ষেত্র অন্তর্ভুক্ত রয়েছে।
