Which version of Sql server you are currently using. In sql server 2014 onwards microsoft has introduced In-Memory OLTP where you can create table in memory check this https://www.simple-talk.com/sql/learn-sql-server/introducing-sql-server-in-memory-oltp/ Thanks, Manish

public DataTable GetDataTableFromCacheOrDatabase () { DataTable dataTable = HttpContext . Current . Cache [ "secret key" ] as DataTable ; if ( dataTable == null ) { dataTable = GetDataTableFromDatabase (); HttpContext . Current . Cache [ "secret key" ] = dataTable ; } return dataTable ; } You're going to need some mechanism to flush the data table from the cache if it changes. For example you could use an SqlCacheDependency. As requested, to clear the cache an hour after the table is added you would do: HttpContext . Current . Cache . Insert ( "secret key" , dataTable , null , DateTime . Now . AddHours ( 1 ), System . Web . Caching . Cache . NoSlidingExpiration );
