How does LINQ behave when expression trees become too large for provider translation limits?

Large expression trees may fail translation or trigger partial evaluation depending on provider capabilities.

LINQ providers like EF Core parse expression trees recursively. Extremely large trees (deep nesting, multiple joins, long predicate chains) can exceed internal complexity thresholds or lead to inefficient SQL generation. Some providers attempt partial evaluation (executing part in-memory), while others throw runtime exceptions. This creates unpredictable behavior in production systems when query complexity grows organically.
