Table Splitting in Entity Framework allows storing related entities in separate tables while maintaining a one-to-one relationship between them. This is useful for organizing data and improving performance in certain scenarios.

Entity Splitting affects the database schema by reducing redundancy and improving data integrity. By breaking down a single entity into multiple entities mapped to distinct tables, it helps in organizing and maintaining data effectively.

Entity Splitting involves mapping a single entity to multiple tables, which can lead to more complex SQL queries and joins. This complexity can potentially degrade query performance, especially in scenarios where there are frequent joins across multiple tables. Therefore, using Entity Splitting in a complex data model might result in decreased query performance.

Entity Framework automatically updates the entity configuration when changes are made to the database schema in the context of Table Splitting. This means that developers do not need to manually synchronize the entity configuration with the database schema changes, simplifying the maintenance process and reducing the chances of errors.

Entity Splitting and Table Splitting can be used together for a single entity when there is a need to separate related properties into different tables while also mapping some properties to the same table. This allows for greater flexibility in managing the database schema and optimizing data storage, especially in scenarios where certain properties need to be stored in separate tables for performance or normalization reasons.

Entity Splitting involves splitting an entity's properties across multiple tables, which are then connected via a foreign key relationship. This allows mapping different entities to the same table.

Table splitting in Entity Framework requires that both entities sharing the same primary key. This means that both the main entity and the related entity must have the same primary key, allowing Entity Framework to correctly map and split the tables.

Entity splitting in Entity Framework is configured using the Split method in the Fluent API. This method allows you to specify how a single entity in your model maps to multiple tables in the database, effectively splitting the entity's properties across those tables.

In Table Splitting, related entities are typically loaded eagerly. This means that when you fetch an instance of the main entity, Entity Framework also loads the related entity or entities that are mapped to the same underlying table. Eager loading helps in avoiding additional database round trips when accessing related entities.

Eager loading ensures that all related data is loaded at the same time as the main entity. This is particularly useful when dealing with Table Splitting scenarios where all parts of an entity need to be fetched together.
