Answer
CHECKPOINT flushes dirty pages to disk to reduce crash recovery time and manage buffer pressure.
Quick Answer
CHECKPOINT flushes dirty pages (modified but not yet written) from the buffer pool to disk. It reduces crash recovery time — SQL Server only needs to replay changes since the last checkpoint instead of replaying the whole log. Automatic checkpoints run periodically; you can also force one manually.
