Memory-Optimized Tables support in SQL Server EF Core Database Provider

Memory-Optimized Tables are a feature of SQL Server where the entire table resides in memory. A second copy of the table data is maintained on disk, but only for durability purposes. Data in memory-optimized tables is only read from disk during database recovery. For example, after a server restart.

Configuring a memory-optimized table

You can specify that the table an entity is mapped to is memory-optimized. When using EF Core to create and maintain a database based on your model (either with migrations or EnsureCreated), a memory-optimized table will be created for these entities.

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Blog>().ToTable(b => b.IsMemoryOptimized());
}
