EFCore Will Not Directly Insert into Database

EF Core does not insert data directly into the database during insertion operations; instead, it first caches the data in memory. Data will only be inserted into the database under the following conditions:

• Explicitly calling the SaveChanges() method
• The context object is disposed
• The configured batch insert quantity of the context is reached

The benefits of EF Core caching data in memory include:

Improved performance: Batch inserting data can enhance the database performance.

Error reduction: Before inserting data into the database, EF Core can validate the data to ensure its validity.

The drawbacks of EF Core caching data in memory include:

Increased memory usage: If the volume of cached data is excessive, it may lead to memory overflow.

Risk of data loss: If the context object is unexpectedly disposed of, the cached data will be lost.

By default, EF Core caches all changes in memory. You can disable automatic change detection by setting the ChangeTracker.AutoDetectChangesEnabled property.
