1. 解释什么是transient in-memory database(瞬时内存数据库) 瞬时内存数据库(Transient In-Memory Database)是一种数据库系统,它在运行时将所有数据存储在计算机的主内存中,而不是持久化到磁盘上。这意味着当数据库系统关闭或崩溃时,存储在内存中的数据将会丢失。SQLite 和 DuckDB 等数据库系统都支持这种模式。
Loading of table metadata into memory of an in-memory database is initiated. The table metadata is persisted across pages in a page chain. Thereafter, a plurality of metadata objects are materialized into memory that each include an object handle pinning an underlying persisted page in the page...
In subject area:Computer Science Transient memory in the context of Computer Science refers to a type of memory that is continually perishing and temporary, similar to how oral historical memories are built up and fade away over time through oral transmission across generations. ...
Perform retry operations only when the faults are transient (typically indicated by the nature of the error) and when there's at least some likelihood that the operation will succeed when retried. There's no point in retrying operations that attempt an invalid operation, like a database update...
If your client program connects to your database in Azure SQL Database by using the .NET Framework class System.Data.SqlClient.SqlConnection, use .NET 4.6.1 or a later version (or .NET Core) so that you can use its connection retry feature. For more information about this feature, see...

Sleep has long been considered as a state of behavioral disconnection from the environment, without reactivity to external stimuli. Here we questioned this ‘sleep disconnection’ dogma by directly investigating behavioral responsiveness in 49 napping pa
