view=sql-server-ver15&redirectedfrom=MSDN 同步和异步只两个节点之间的数据等待模式,这里每个节点都有一个选项,那么这个同步模式(SYNCHRONOUS_COMMIT)和异步模式(ASYNCHRONOUS_COMMIT)又该如何理解呢? 直接翻译成人话: 1,主节点异步提交模式:如果主要副本配置为“异步提交模式” ,则从节点不管是同步或者异步,主节点提...
Availability Mode: Synchronous Commit vs Asynchronous Commit Connection Mode: Read-only vs None The assessment aggregates all the configuration and performance data and tries to find the best match across various Azure SQL service tiers and configurations and picks a configuration that can match or ex...
A transformation with synchronous outputs processes each input row as it passes through the component. A transformation with asynchronous outputs waits until it has received all input rows to complete its processing. This topic discusses a synchronous transformation. For information about asynchronous ...
Fully durable transaction commits are synchronous and report a commit as successful and return control to the client only after the log records for the transaction are written to disk. Delayed durable transaction commits are asynchronous and report a commit as successful before the log records for ...
PostgreSQL异步提交(Asynchronous Commit)的功能: 这个功能oracle中也是到oracle11g R2才有的功能。因为在很多应用场景中,当宕机时是允许丢失少量数据的,这个功能在这样的场景中就特别合适。在PostgreSQL9.0中把 synchronous_commit设置为false就打开了这个功能。需要注意的是,虽然设置为了异步提交,当主机宕机时,PostgreSQL只...

(the exact amount depends on the amount and type of audit records generated). The choice of asynchronous or synchronous is controlled by the QUEUE_DELAY option of the CREATE AUDIT DDL (explained below); by default, the value is 1000, which indicates that SQL Server Audit will queue the ...
