मेरे पास अपेक्षाकृत बड़ी तालिका है (वर्तमान में 2 मिलियन रिकॉर्ड) और जानना चाहूंगा कि क्या यह तदर्थ प्रश्नों के लिए प्रदर्शन में सुधार करना संभव है। शब्द तदर्थ यहाँ महत्वपूर्ण है। अनुक्रमणिका जोड़ना एक विकल्प नहीं है (स्तंभों पर पहले से ही अनुक्रमित हैं जो सबसे अधिक सामान्य रूप से उद्धृत हैं)।
100 सबसे हाल ही में अपडेट किए गए रिकॉर्ड को वापस करने के लिए एक सरल क्वेरी चल रही है:
select top 100 * from ER101_ACCT_ORDER_DTL order by er101_upd_date_iso desc
कई मिनट लगते हैं। नीचे निष्पादन योजना देखें:
तालिका स्कैन से अतिरिक्त विवरण:
SQL Server Execution Times:
CPU time = 3945 ms, elapsed time = 148524 ms.
सर्वर बहुत शक्तिशाली है (मेमोरी 48 जीबी रैम, 24 कोर प्रोसेसर से) एसक्यूएल सर्वर 2008 आर 2 एक्स 64 चला रहा है।

मुझे 1,000,000 कोड वाली तालिका बनाने के लिए यह कोड मिला। मुझे लगा कि मैं SELECT TOP 100 * FROM testEnvironment ORDER BY mailAddress DESC
कुछ अलग सर्वरों पर चला सकता हूं ताकि पता लगाया जा सके कि सर्वर पर मेरी डिस्क एक्सेस स्पीड खराब थी या नहीं।

लेकिन तीन परीक्षण सर्वरों पर क्वेरी लगभग तुरंत चली। क्या कोई इसे समझा सकता है?
अपडेट २
टिप्पणियों के लिए धन्यवाद- कृपया उन्हें आते रहें ... उन्होंने मुझे गैर-संकुल से प्राथमिक कुंजी सूचकांक को बदलने की कोशिश की, बजाय दिलचस्प (और अप्रत्याशित?) परिणामों के साथ।
गैर-संकुल:
SQL Server Execution Times:
CPU time = 3634 ms, elapsed time = 154179 ms.
क्लस्टर किया गया:
SQL Server Execution Times:
CPU time = 2650 ms, elapsed time = 52177 ms.
यह कैसे संभव है? Er101_upd_date_iso कॉलम पर एक इंडेक्स के बिना क्लस्टर इंडेक्स स्कैन का उपयोग कैसे किया जा सकता है?
