precomputed 中文意思是什麼

precomputed 解釋
預先計算的
  1. Since summary data is precomputed in the mqts, db2 optimizer may rewrite a specific query to access an mqt instead of based tables because the optimizer can recognize if result sets can be derived from an mqt with less predicted cost

    因為匯總數據在mqt中預先計算，所以db2優化器可以改寫特定查詢來訪問mqt ，而不是基礎表，因為優化器可以識別是否能以較少的預計成本從mqt得到結果集。
  2. Not using the precomputed partitions optimization

    沒有使用預計算分區優化。
  3. Precomputed partitions for filtered merge publications

    已篩選合併發布的預計算分區
  4. Use the precomputed partitions optimization if possible

    請盡可能使用預計算分區優化。
  5. Requirements for using precomputed partitions

    使用預計算分區的要求
  6. Performance of precomputed partitions

    預計算分區的性能
  7. Optimizing parameterized filter performance with precomputed partitions

    >使用預計算分區優化參數化篩選器的性能
  8. Precomputed partitions is also a requirement for using logical records on filtered publications

    預計算分區也是在已篩選的發布上使用邏輯記錄的一項要求。
  9. Precomputed partitions is a performance optimization that can be used with filtered merge publications

    預計算分區是一種性能優化方法，可用於已篩選的合併發布。
  10. If a publication does not meet the requirements, it can be changed, and then precomputed partitions can be enabled

    如果發布不滿足下列要求，可對其先進行更改，然後即可啟用預計算分區。
  11. The rank that is precomputed and stored in the full - text catalog when the

    當使用預計算排名數據時，請記住由
  12. Use precomputed rank data stored in the full - text catalogs

    的freetexttable查詢使用存儲在全文目錄中的預計算排名數據。
  13. Without precomputed partitions, partition evaluation must be performed for each change made to a filtered column at the publisher since the last time the merge agent ran for a specific subscriber, and this process has to be repeated for every subscriber that synchronizes with the publisher

    如果沒有預計算分區，那麼，自上次為特定訂閱服務器運行合併代理之後，對發布服務器上已篩選列每進行一次更改都必須執行分區計算，而且對與該發布服務器同步的每個訂閱服務器都要重復這一過程。
  14. There is a small performance cost with precomputed partitions when changes are uploaded from the subscriber to the publisher, but the bulk of merge processing time is spent evaluating partitions and downloading changes from the publisher to the subscriber, so the net gain can still be significant

    在將更改從訂閱服務器上載到發布服務器時，盡管使用預計算分區會產生少量的性能開銷，但大部分合併處理時間用於計算分區以及將更改從發布服務器下載到訂閱服務器上，所以凈的性能收益仍然很顯著。
  15. This stored procedure returns information about the supplied filter, including whether or not the filter qualifies for use with precomputed partitions

    此存儲過程返回所提供的篩選器的相關信息，包括篩選器是否適合用於預計算分區。
  16. The use of precomputed partitions is a new performance optimization for merge publications that use parameterized filters referred to as " dynamic filters " in previous versions

    預計算分區的使用是對使用參數化篩選（在早期版本中稱為「動態篩選器」 ）的合併發布的新的性能優化。
  17. Used a precomputed endgame database defining perfect play for all positions involving 8 or fewer pieces on the board, a total of 444 billion positions

    當棋盤上僅剩下8個或更少的旗子時，它使用一個預先計算好的殘局數據庫在共計444 ， 000 ， 000 ， 000個節點里選出最完美的走法。
