Term	Kind	Topic	What it is
Open Table Format Apache Iceberg, Delta Lake, Apache Hudi	protocol	Data Lakes & Lakehouses	A metadata layer over files in object storage that supplies ACID transactions, schema evolution and time travel — the thing that turns a data lake into a lakehouse.
Two-Phase Locking 2PL	protocol	Transactions & Isolation	The concurrency control protocol behind serializable isolation — acquire locks in a growing phase, release only in a shrinking phase, never interleaving the two.
