আমার তুলনামূলকভাবে বড় টেবিল রয়েছে (বর্তমানে ২ মিলিয়ন রেকর্ডস) এবং অ্যাড-হক অনুসন্ধানগুলির জন্য পারফরম্যান্স উন্নত করা সম্ভব কিনা তা জানতে চাই। অ্যাড-হক শব্দটি এখানে মূল কী। সূচকগুলি যুক্ত করা কোনও বিকল্প নয় (কলামগুলিতে ইতিমধ্যে এমন সূচকগুলি রয়েছে যা বেশিরভাগভাবে অনুসন্ধান করা হয়)।
সর্বাধিক আপডেট হওয়া 100 টি রেকর্ড ফেরত দিতে একটি সাধারণ ক্যোয়ারী চালানো:
select top 100 * from ER101_ACCT_ORDER_DTL order by er101_upd_date_iso desc
কয়েক মিনিট সময় নেয়। নীচে বাস্তবায়ন পরিকল্পনা দেখুন:
টেবিল স্ক্যান থেকে অতিরিক্ত বিশদ:
SQL Server Execution Times:
CPU time = 3945 ms, elapsed time = 148524 ms.
সার্ভারটি বেশ শক্তিশালী (মেমরির 48 গিগাবাইট র্যাম, 24 কোর প্রসেসর থেকে) এসকিএল সার্ভারে চালিত 2008 আর 2 এক্স 64।
হালনাগাদ
আমি এই কোডটি 1,000,000 রেকর্ড সহ একটি টেবিল তৈরি করতে পেয়েছি। আমি ভেবেছিলাম যে SELECT TOP 100 * FROM testEnvironment ORDER BY mailAddress DESC
সার্ভারে আমার ডিস্ক অ্যাক্সেসের গতি খুব কম কিনা তা জানতে আমি কয়েকটি আলাদা সার্ভারে চালিত করতে পারি ।

তবে তিনটি পরীক্ষার সার্ভারে ক্যোয়ারী প্রায় তাত্ক্ষণিকভাবে চলেছিল। কেউ কি এই ব্যাখ্যা করতে পারেন?

মন্তব্যের জন্য আপনাকে ধন্যবাদ - দয়া করে তাদের আগত রাখুন ... তারা আমাকে ক্লাস্টারবিহীন থেকে ক্লাস্টার না করে বরং আকর্ষণীয় (এবং অপ্রত্যাশিত?) ফলাফলের সাথে প্রাথমিক কী সূচকটি পরিবর্তন করার চেষ্টা করেছিল।
ক্লাস্টারবিহীন:
SQL Server Execution Times:
CPU time = 3634 ms, elapsed time = 154179 ms.
ক্লাস্টার্ড:
SQL Server Execution Times:
CPU time = 2650 ms, elapsed time = 52177 ms.
এটা কিভাবে সম্ভব? Er101_upd_date_iso কলামে একটি সূচি ছাড়া একটি ক্লাস্টারড ইনডেক্স স্ক্যানটি কীভাবে ব্যবহার করা যেতে পারে?
