Tenho uma tabela relativamente grande (atualmente 2 milhões de registros) e gostaria de saber se é possível melhorar o desempenho para consultas ad-hoc. A palavra ad-hoc é a chave aqui. Adicionar índices não é uma opção (já existem índices nas colunas que são consultados com mais freqüência).
Executar uma consulta simples para retornar os 100 registros atualizados mais recentemente:
select top 100 * from ER101_ACCT_ORDER_DTL order by er101_upd_date_iso desc
Demora vários minutos. Veja o plano de execução abaixo:
Detalhes adicionais da verificação da tabela:
SQL Server Execution Times:
CPU time = 3945 ms, elapsed time = 148524 ms.
O servidor é muito poderoso (de memória RAM de 48 GB, processador de 24 núcleos) rodando sql server 2008 r2 x64.

Eu encontrei este código para criar uma tabela com 1.000.000 de registros. Pensei que poderia rodar SELECT TOP 100 * FROM testEnvironment ORDER BY mailAddress DESC
em alguns servidores diferentes para descobrir se a velocidade de acesso ao meu disco era baixa no servidor.
WITH t1(N) AS (SELECT 1 UNION ALL SELECT 1),
t2(N) AS (SELECT 1 FROM t1 x, t1 y),
t3(N) AS (SELECT 1 FROM t2 x, t2 y),
Tally(N) AS (SELECT TOP 98 ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM t3 x, t3 y),
Tally2(N) AS (SELECT TOP 5 ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM t3 x, t3 y),
Combinations(N) AS (SELECT DISTINCT LTRIM(RTRIM(RTRIM(SUBSTRING(poss,a.N,2)) + SUBSTRING(vowels,b.N,1)))
FROM Tally a
CROSS JOIN Tally2 b
CROSS APPLY (SELECT 'B C D F G H J K L M N P R S T V W Z SCSKKNSNSPSTBLCLFLGLPLSLBRCRDRFRGRPRTRVRSHSMGHCHPHRHWHBWCWSWTW') d(poss)
CROSS APPLY (SELECT 'AEIOU') e(vowels))
SELECT IDENTITY(INT,1,1) AS ID, a.N + b.N AS N
INTO #testNames
FROM Combinations a
CROSS JOIN Combinations b;
SELECT IDENTITY(INT,1,1) AS ID, firstName, secondName
INTO #testNames2
FROM (SELECT firstName, secondName
FROM (SELECT TOP 1000 --1000 * 1000 = 1,000,000 rows
N AS firstName
FROM #testNames
ORDER BY NEWID()) a
CROSS JOIN (SELECT TOP 1000 --1000 * 1000 = 1,000,000 rows
N AS secondName
FROM #testNames
ORDER BY NEWID()) b) innerQ;
SELECT firstName, secondName,
firstName + '.' + secondName + '@fake.com' AS eMail,
CAST((ABS(CHECKSUM(NEWID())) % 250) + 1 AS VARCHAR(3)) + ' ' AS mailAddress,
(ABS(CHECKSUM(NEWID())) % 152100) + 1 AS jID,
IDENTITY(INT,1,1) AS ID
INTO #testNames3
FROM #testNames2
SELECT IDENTITY(INT,1,1) AS ID, firstName, secondName, eMail,
mailAddress + b.N + b.N AS mailAddress
INTO testEnvironment
FROM #testNames3 a
INNER JOIN #testNames b ON a.jID = b.ID;
--CLEAN UP USELESS TABLES
DROP TABLE #testNames;
DROP TABLE #testNames2;
DROP TABLE #testNames3;
Mas nos três servidores de teste a consulta foi executada quase que instantaneamente. Alguém pode explicar isso?
Atualização 2
Obrigado pelos comentários - por favor, continuem vindo ... eles me levaram a tentar alterar o índice de chave primária de não agrupado para agrupado com resultados bastante interessantes (e inesperados?).
Não agrupado:
SQL Server Execution Times:
CPU time = 3634 ms, elapsed time = 154179 ms.
Agrupado:
SQL Server Execution Times:
CPU time = 2650 ms, elapsed time = 52177 ms.
Como isso é possível? Sem um índice na coluna er101_upd_date_iso, como uma varredura de índice clusterizado pode ser usada?
