Specifies the amount of compression that will be used by the compression routines during push and pull operations 指定壓縮例程在推送和提取操作期間將使用的壓縮量。
If the data from the server must be refreshed after a particular push to the server , the application does not allow additional changes to the table until the push and pull operations are both complete 如果在到服務(wù)器的特定推送之后必須刷新來自服務(wù)器的數(shù)據(jù),則在推送和請求操作均完成之前,應(yīng)用程序不允許對表進行其他更改。
Because a pull operation requires that the specific local table not be present at the time of the pull , and the table is created during the process of pulling the data from the server , the table being pulled cannot be accessed until the pull operation is complete 因為請求操作要求在推送時不存在特定本地表,而且該表是在從服務(wù)器請求數(shù)據(jù)的過程中創(chuàng)建的,所以在請求操作完成之前,無法訪問被請求的表。
