Method for distributed table joins in a network
The patent US12032576B2 outlines a method for efficiently performing joins of multiple tables within a computer system. The process begins with the system receiving a query that specifies the tables to be joined. It identifies entries in a first table that meet the criteria outlined in the query and sets flags in an active flag structure to indicate which entries satisfy the criteria. The method further involves identifying foreign keys in a second table that correspond to the identified entries in the first table. These keys are then used to generate multiple requests for the corresponding entries in the second table, with the system determining memory locations for these entries and sending the requests accordingly. The flags in the first active flag structure are updated based on the responses received from the requests.
Additional claims detail specific aspects of the method, such as the inclusion of a "where" component in the query, the use of boolean values for flags, and the potential for remote direct memory access (RDMA) requests. The identifiers for the keys may utilize hash functions, and the responses can indicate the location of the second entries or the status of the flags. The method also allows for the updating of flags based on the responses received, ensuring that the system accurately reflects the current state of the data being processed. Overall, this patent presents a structured approach to managing data joins, enhancing the efficiency and accuracy of database operations.
