Described are techniques for identifying primary and foreign keys to build a schema. A primary key of a query table of a data lakehouse, which may consist of multiple columns, is identified. The top n-similar columns of the tables of the data lakehouse are then identified to identify the joinable tables using the primary key as a query using column embeddings. A list of candidate joinable tables is then identified based on the identified top n-similar columns of tables of the data lakehouse. Joinable tables from the list of candidate joinable tables are selected that satisfy an inclusion dependency constraint. The foreign keys having full containment with the primary key of the query table are then identified from the selected joinable tables. Such identified primary and foreign keys are utilized to build / discover the schema, such as a relational schema, of the data lakehouse.

This invention relates to a firewall data processing method based on endpoint security protection. It establishes an endpoint connection management mechanism, maintains an active connection table and a state hook mapping table, and associates outbound connections with process identifiers, user identities, data payload summaries, and creation times to form state hooks. Hook verification is triggered when the endpoint state changes. If sensitive privilege escalation or behavior deviating from the initial digest is detected, the connection priority is dynamically adjusted, and rate limiting, blocking, or transition to observation mode is implemented. Access path consistency verification is performed on outbound connections, comparing DNS requests, process calls, and actual packet paths. If unexplained path offsets exist, the source is traced and the path is reconstructed. Connection behavior is periodically split according to operating system event granularity, and concurrent or abrupt behavior is logically redefined into multiple sub-sessions with corresponding policies applied. Transmission delays are applied to reversible connection operations, and action chain tracing is activated to determine whether to restore or terminate the connection.
